Safe human-robot co-working through formal methods

Strict international standards govern the interaction between humans and machines in the workplace. For example, robots must often be separated from humans with cages or light curtains, and cannot operate when humans are inside their workspace.

If a control strategy can guarantee that robots and humans can work together safely, this is an important step towards allowing humans and machines to share a collaborative workspace in industrial settings.

Equipment Used

Vicon Vantage

Vantage is Vicon’s flagship range of cameras. The sensors have resolutions of 5, 8 and 16 megapixels, with sample rates up to 2000Hz – this allows you to capture fast movements with very high accuracy. The cameras also have built-in temperature and bump sensors, as well as a clear display, to warn you if cameras have moved physically or due to thermal expansion. High-powered LEDs and sunlight filters mean that the Vantage is also the best choice for outdoor use and large volumes.

Vero

The compact Vero cameras have sensor resolutions of either 1.3 or 2.2 megapixels. The camera has a variable zoom lens, which makes it especially suited for smaller capture volumes where it is especially important to have an optimum field of view. The Vero’s attractive price combined with its light weight and small size makes it a great choice for smaller labs and studios.

Tracker

Tracker has been designed for the requirements and workflow of Engineering users wanting to track the position and orientation of objects with as little effort and as low latency as possible. Perfect for many applications in robotics, UAV tracking, VR and human-machine interaction, Tracker lets you define what you want to track with a couple of mouse clicks – and then you can just leave in the background tracking. A simple SDK lets you connect the output data stream to your own software.

Human-Robot-Interaction

We often use machines because they can carrying heavy things and they never need to rest. But people can also do things that machines can’t. We can use our eyes, fingers, and senses better than machines, and different from what you might see in films, machines still can’t think well.

So we often want machines and people to work together. The most important thing here is safety. With our 6x Vicon Vero v1.3 cameras, we are able to analyse this interaction and improve the control algorithm of the robot.
