Accerion Triton - White paper



Accerion Navigation Systems White Paper:
 
 
Accerion systems effectively “map” the ground using sophisticated optical technology to provide absolute positioning.

USP’s

Provides sub-mm positioning
Requires no infrastructure/landmark features

Limitations:

No dynamic awareness 

Niche applications:

Automated / Semi-Automated vehicles which require high accuracy  positioning:

These include:
 
Precision docking (for goods transfer or vehicle charging) where other technologies such as Lidar cannot provide the required level of positional accuracy.
 
Narrow aisle warehousing where positional accuracy of the forklift is critical.

Automation in feature devoid environments

Block stacking type applications:
 
Many “tidal” distribution centres (such as dairy or postal) utilise block-stacking techniques where an empty featureless warehouse is progressively populated and depopulated with pallets or stillages. 
 
This type of environment is a nightmare for traditional navigation technologies because there are no visible permanent features to determine position against and triangulation techniques are impossible due to stack height.
 
Here the floor or ceiling is the only fixed features to navigate against.

Swarm robot (Keva type) environments

Often these are large featureless or repetitive non-unique feature environments.
 
Most importantly they are devoid of extraneous vehicles/objects.
 
Each AGV / mobile robot equipped with the Triton system will be controlled by a central computer which will precisely map position, thus without the need for dynamic awareness sensors AGVs / mobile robots can move autonomously, without the threat of collision.

Exclusions / considerations

Accerion technology enables precise positioning.
 
Therefore in a strictly regulated and controlled environment (such as the Swarm robot case above), no other sensors are necessary. This approach would, therefore, provide a cost-effective solution.
 
Unfortunately, most factory environments are populated by people and or by other non-system controlled moving or stationary objects (think of the pallet truck that somebody has left at the side of the aisle) In this environment any moving AGV requires some form of dynamic awareness (with or without safety certification). 
 
The upside is that fusion of the output information from the dynamic awareness sensor (LiDAR, Camera, Radar, Ultrasonic) combined with that from the Accerion system is richer (effectively combining two perspectives). 
 
A combination solution is often more effective and less expensive than a  LiDAR (only) solution where multiple LiDARs are needed to facilitate efficient SLAM localisation.

Can humans and robots work together?



How AI will transform the workplace
 
AI refers to computer systems that can sense their environment, think, learn and then take action as a result. This ability to respond to the environment stands artificial intelligence apart from the automation of routine tasks. Machine learning algorithms and chatbots are examples of AI that are already used by businesses today.
 
Humans working alongside robots isn’t a new idea. It’s been part of manufacturing, for example, for many years. However, as the AI becomes more advanced, the number of tasks which robots will be able to complete will increase. This will change the relationship between humans and robots.
 
Robots today and tomorrow
 
Often when we see robots on car production lines, it’s in a fixed place and carrying out a single task. The emerging vision, however, features smaller, lighter, nimbler robots. They’ll be able to move around, learn and generate real-time data that will enable them to make basic decisions about their tasks and motions in milliseconds.
 
Also, these robots are designed to safely share the workspace with humans, aiding in and collaborating on a variety of tasks, from inserting shock absorbers, to packaging medical supplies.
 
Studies have shown that productivity is at its highest when robots and humans are working together, rather than either working on their own. But what challenges does coworking bring? What are the benefits and which industries will benefit the most?
 
Challenges
 
One of the main challenges of a hybrid working environment is the potential job losses. In a study by the consultancy firm Oxford Economics, the rapidly growing use of robots is expected to have a profound impact on jobs across the world, resulting in up to 20 million manufacturing job losses by 2030.
 
The global analysis of 29 advanced economies found that each new industrial robot eliminated as many as 1.6 manufacturing jobs on average.
 
Another challenge is that much of the technology is untested. Take the driverless car, for example. A woman in Arizona lost her life when she was struck by a driverless car in 2017. Although there was someone inside the car, they weren’t able to react to the situation and prevent it.
 
If humans can’t trust the robots and technology they’re working alongside, there will be trouble ahead. The possibilities may seem endless, but if robots don’t make the world around us safer, it’s going to be a difficult sell.
 
They’re not like us
 
Can humans work well in collaboration with something which they don’t associate with? Some researchers believe that we’ll need to humanise robots more, perhaps even let them make mistakes, as humans do. However, if this were to happen, it would erase one of the main advantages that robots have over humans, in that they don’t make as many (if any) mistakes.
 
Benefits
 
Built with embedded cameras, lasers and sensors, as well as limited cognition and self-programming capabilities, many robots can take in ambient data — temperature, humidity, speed of the line, etc — and make decisions about their next course of action in a millisecond or less.
 
Robots can be put to work in dangerous environments, such as natural disasters, the front line and on construction sites.
 
In extremely busy periods, a robot can work 24 hours a day, without becoming fatigued or stressed. This would stop the staff being overworked and would protect peoples’ wellbeing at work.
 
Far from taking jobs away, robots can actually create jobs. The more that robots are used in the workplace the greater need we’ll have for people skilled in engineering and technology.
 
To get to the optimum performance, it will take time and there will need to be an investment from companies to reap the full benefits of robotics.
 
Which industries will benefit the most from robotics?
 
Healthcare
The healthcare sector is already using AI to find links to disease, diagnosis and treatment. And it seems it’s an industry which can benefit even further.  The BBC reported that machine learning is able to spot the signs of heart disease in the scans of patients more accurately than doctors alone.
 
Automotive
Completely driverless cars may still be a way off, but robotics will have a huge impact on the automotive industry. Robots co-working with people will make production more efficient and the end product will include more technology which will make our driving experience safer and easier.
 
Ecommerce
Ecommerce is making good use of robotics, especially within customer care. Many websites now have chatbots, available to us if we have any questions about our purchase. AI also enables retailers to manage and interpret customer data. They can then push products based on a customer’s previous sales, which is a great way to increase your revenue.
 
And the huge warehouses which pick our purchases for us have also benefited from robotics. Having robots which can learn a number of routes to fetch certain products is making online shopping even quicker.
 
Making it work
 
For humans and robots to really work in harmony, businesses must consult with their workforce. According to the commission on workers and technology, run by the Fabian Society and the Community trade union, almost six in 10 employees across Britain in a poll said their employers didn’t give them a say on the use of new technologies.

New products, more news and more exhibitions for 2019
 
 



Last year was very busy for us here at Sentek. We launched the new Accerion Jupiter and Hokuyo YVT 35LX, we went to LogiMAT, SPS and the Liverpool Robotics Showcase. And we also helped a German University to win the RoboRace 2018!
                              
You can read about all of the last years activities in our blogs

Here are some of our personal highlights....
 
LogiMAT 2018
 
Held in Stuttgart, in March, LogiMAT is the biggest exhibition in Europe for warehouse logistics.
 
We showcased the Hokuyo UAM-05LP Safety Laser Scanner, which is made for the European AGV market, and is the smallest scanner of its kind available.
 
LogiMAT was also a chance for us to launch the new Accerion Jupiter module which got a lot of interest. The Jupiter delivers accurate positioning, inside or out, without infrastructure, and it can be integrated into new and existing vehicles.

We also went to Nuremberg in November for the SPS IPC Drives show. We've just been back to LogiMAT for the 2 019 show and we will be back at SPS in November. 
 
3D LiDAR scanner – YVT 35LX
 
Another exciting new product for 2018 was the YVT-35LX. Instead of using multiple Hokuyo LiDARs, computing power & external devices like ‘pan tilts’, the Hokuyo YVT-35LX can provide point cloud data all by itself.
 
With a wide field of view, the YVT-35LX gives you a 210° horizontal and a 40° vertical scanning angle. And the detectable range is 35m to the front and 14m to the sides.

The Hokuyo YVT-35LX 
 
Here are just some of the applications for the Hokuyo YVT-35LX 3D LiDAR scanner:
 
  • Detecting surroundings for robots.
  • Container profiling and positioning at busy ports.
  • Obstacle detection and pallet shape on forklift trucks.
  • Smart farming and agriculture.
  • Depth measurement in the construction industry.
  • GEO mapping.
  • Counting people at building entrances/exits.
 
With this scanner’s capabilities, we believe it can provide a range of industries with new ways of working.
 
Over the line first at RoboRace
 
We were approached by Johannes Betz, a post-doc researcher from the Technical University of Munich and the Chair of Automotive Technologies. With his team, he was preparing to undertake an exciting research project in the area of autonomous and self-driving vehicles with the aim of taking part in the RoboRace.

They needed a Hokuyo LiDAR device and we were happy to help.
 
The LiDAR device attached to the car.
 
The team said that compared to other LiDAR devices, the Hokuyo performed the best by far. It’s data performance regarding LiDAR points, velocities and distance data are far more accurate and consistent. On top of its performance, the Hokuyo LiDAR is also much more robust than similar devices. The Hokuyo LiDAR was crucial in helping complete the project successfully.
 
And this year?
 
We’re not resting on our laurels for 2019, we've already been to LogiMAT 2019. You can read more about that below.

 You’ll be able to find us at some new shows, as well as SPS. We’ll be launching some more new products too.
 
Our blogs will keep you up-to-date with everything we’re doing, so make sure you check-in each month. You’ll find out more about cleaning robots, how humans are working alongside robots, how robots are helping the agricultural industry, and you’ll hear from some of our customers too.
 
It’s shaping up to be another exciting year at Sentek.

LogiMAT 2019

We are back in the office after a very busy last week at LogiMAT 2019. 

As always the stand was filled with people interested in the vast capabilities of our LiDAR scanners and Radar units. 


 

The Sentek stand at LogiMAT 2019

Alongside the normal demonstrations of our Hokuyo UAM-05LP Safety Laser Scanner and PPT Radar Ranger collision avoidance units we had a brand new scanner on display. 

The Hokuyo URM-40LC-EW is a hybrid scanner with area setting and data output functions. With its 40m range and IP67 rating, it's a great solution for many applications in the outdoor environment.

The future of Robotics and Automation




We may not yet be travelling in driverless cars and have robot butlers at home, but in the past few decades, Robotics and Automation have evolved and grown dramatically (hopefully in some part due to Sentek Solutions!).
 
Reducing costs and improving productivity are increasingly important in today’s ever more competitive environment. Needless to say, Robotics and Automation can eliminate the tedium and improve the efficiency of many processes with the knock-on benefit of reducing running costs and improving profitability.
 
What do Robotics and Automation actually mean? We’ll walk you through the differences and outline ways they can help to improve operational processes. This is probably best addressed by turning things around.
 
What do we mean by Automation?
 
The definition of Automation is - the use of machines and technology to make processes run on their own without human input. For example, a car production line.
 
What do we mean by Robotics?
 
Essentially robotics covers the many different machines designed and built to enable Automation.
 
Really, Automation and Robotics go hand in hand. Returning to the car assembly line example; robots fulfil jobs that may have previously been carried out by people.
 
As well as completing tasks which would be considered dangerous, Robotic and Automated applications are cheaper, more efficient, make fewer mistakes and can run for 24 hours every day.
 
Also, we should not forget that robots can also carry out “superhuman” tasks impossible for mere flesh and blood. After all, how many people can pick up a car and move it with submillimetre precision or work in toxic inhospitable environments?
 
How can these technological developments help to grow my business?
 
If a task is routine, repetitive and uses the same components it can be easily automated. Clearly as with all such projects the business case needs to be justified (capital expenditure against operating costs savings) and payback period determined.
 
Other tasks which have elements of variability in the process, location or components need to use cleverer (autonomous /semi-autonomous) robots and of course, this increases the capital cost.
 
Critically this type of robot needs to be aware of its environment and/or communicate with other production line equipment so that it can alter its behaviour according to circumstances. This is where Sentek Solutions products come in.

Seeing what’s around
 
Our comprehensive range of LiDARs from Safety Laser Scanners to 3D devices like the Hokuyo YVT-35LX allow the host robot to understand the surrounding environment and even determine what component it will be working with.
 
This can be used to:
 
  • Determine location SLAM
  • If mobile; safely and efficiently avoid obstacles
  • Allow correct recognition and handling of a component, machine or person
  • Ascertain and execute the appropriate operation process


The Hokuyo UTM-30LX-EW is just one of many compact and powerful Hokuyo LiDAR scanners
30m range
Indoor/ Outdoor use
Ethernet connectivity
270º scanning window
0.25º resolution 
IP67 protection category
25ms scan speed
 
 
Knowing exactly where you are
 
Accerion’s Jupiter localisation system enable sub-millimetre positional accuracy, so an AGV/mobile robot can determine exactly where it is.
 
In an ideal world where everything is where it is supposed to be this allows the robot to identify and move to key locations where it can perform its required task. For instance, this can be used for returning the robot consistently to a loading point or a charging station.
 
Unfortunately, neither robots nor humans live in an ideal world. In these cases, this information can be used in conjunction with a LiDAR / Safety Laser Scanner which provides real-time information as to the AGV/ robot’s surroundings.

Communicating with the outside world
 
Hokuyo data transmission devices have been developed specifically for use in fully automated environments.
 
The shorter-range parallel devices are used extensively in semiconductor manufacture where they facilitate communication between material handling robots and/or static “hand over” stations.
 
Longer range serial devices can communicate over distances of up to 200m with up to 100MB bandwidth. This type of device tends to be used in automated warehouses and logistic centres.

Up to 400m range

Multiple interface versions available

What’s holding Robotics and Automation back?
 
Initial set up costs for automating projects can be high which may put off some businesses from making the initial investment. Luckily, our products are competitively priced and payback periods can be shorter than one would think.
 
People often believe that Robotics and Automation can only be used in the manufacturing and logistics sectors. This is not the case many different categories of robots have been developed from health care to public service and disaster management. At Sentek Solutions we have many customers who have applications in a wide variety of industries. For Robotics and Automation to proliferate companies need to be innovative and “think out of the box”.

Using a Hokuyo LiDAR to win the RoboRace!



At the end of 2017, we were approached by Johannes Betz, a post-doc researcher from the Technical University of Munich and the Chair of Automotive Technologies. He and his team were preparing to undertake an exciting research project in the area of autonomous and self-driving vehicles with the ultimate aim of taking part in the RoboRace (roborace.com).

In order to help with the project, the team needed a Hokuyo LiDAR device and reached out to Sentek for support. As it was such an exciting project and Sentek have a long stand relationship with TUM and their spin-off companies, we were happy to give our support to the help.

Here is what Johannes had to say when we asked him about the project and how the Hokuyo LiDAR performed and aided the project….        
 


Our team consists of 2 Professors, 6 PHD students, and 25 normal students. We had 3 sub-teams working together on the project. One team for Planning, one team for Perception and one team for Control. These are all key processes in autonomous driving.


The team at the RoboRace event.

Our goal was to develop and evaluate algorithms for those three parts of autonomous driving. In addition, we planned to develop and evaluate additional specific algorithms like a prediction of the adhesion factor, detection of obstacles and planning / implementing a complete and successful race strategy.

Preparing for the RoboRace:

We began with the development of the software in December 2017, our first competition with Roborace was in May 2018 at the Formula E Event in Berlin so we had plenty of time to prepare.

The development was split into three parts:

1: Simulation of the race environment: We used the Roborace simulator

2: Real world testing with the RoboRace DevBot vehicle at the race headquarters in Banbury. England: We did this testing every month and although it was crucial for the development and evaluation it took up a lot of our time and budget.

3: Smart (small) scale testing at the University: This important stage is where we built an autonomous remote controlled car which featured the Hokuyo LiDAR.

The autonomous RC car: In cooperation with some students we built an autonomous RC Car.

This autonomous RC car was a 1:10 scale of a full-sized electric car. Ultrasonic sensors, a stereovision camera and the Hokuyo UST-20LX LiDAR were used to convert the car into a fully autonomous vehicle.


The autonomous remote controlled car featuring the Hokuyo LiDAR.

We used the LiDAR on the remote-controlled car to test our SLAM and Mapping algorithms that we planned to use on the full-sized car. During the project, students used the Hokuyo LiDAR for research. We had 10 Students working with the LiDAR and some are still working with it (Bachelors, Masters, Semester Thesis). Here are some of the projects students are undertaking:

a) Evaluating the performance of different SLAM algorithms and different LiDAR devices.

b) Controlling the car just on range (distance) detections with the LiDAR.

c) Writing SLAM algorithms that process the LiDAR information with GPU power based on the Nvidia Jetson.

d) Writing a sensor fusion algorithm for combining LiDAR and camera information.

e) Writing a sensor fusion algorithm for combining LiDAR and ultrasonic information.

f) Writing a simple scan matcher with LiDAR data only.

g) Writing an algorithm for object detection based on LiDAR and camera data.


LiDAR and camera data.

h) Writing an algorithm for object movement predictions based on LiDAR data.

While using the LiDAR we discovered that when compared to other LiDAR devices we have used the Hokuyo performed the best by far. It’s data performance regarding LiDAR points, velocities and distance data are far more accurate and consistent. On top of its performance, the Hokuyo LiDAR is also much more robust than similar devices. The Hokuyo LiDAR was crucial in helping us complete the project successfully. The LiDAR enabled us to develop a platform for autonomous driving and aid with learning development for PHD students and undergraduate students. It also helped with the acceleration of the complete LiDAR environment development e.g. Mapping, SLAM algorithms and object detection. The LiDAR was crucial for support with the development of software for the RoboRace using the full-sized car.

The RoboRace Event:

In the RoboRace event, we were competing against a team from the University of Pisa. Both teams had to drive the Robo-car around the track three times around the 2km track with a human at the wheel and another three times using only software and no human driver. The time of the second lap of each round is averaged and the team who had the fastest average time won the event. All of our time spent using the LiDAR, doing research, producing algorithms and testing with the autonomous remote-controlled car paid off. We won the RoboRace! Our average lap time was 91.59 seconds which was nearly four seconds faster than the University of Pisa’s time.
 
Alongside the completion of the Roborace project, we have started a brand-new course at the University. It’s called Artificial Intelligence in Automotive Technology. It’s a practical and theoretical course which gives students the opportunity to learn everything about self-driving cars and deep learning. In addition, they are going to code everything on their laptops. At the end of the course, the students are tasked with programming the code for a self-driving “remote controlled” car. The Hokuyo LiDAR is used throughout this course.
