A rotting vision of the future

There's no doubt that autonomous robots fitted out with vision systems can perform some pretty useful tasks. For the military, such robots can help prevent injuries in the battlefield by providing soldiers with a remote insight into the nefarious misdoings of the enemy.  On civvy-street, they can be used for the equally important purposes of improving the environment or keeping the borders of countries safe.

But these conventional robots are predominantly made of rigid resilient materials, many of which are non-biodegradable and have a negative impact on the natural ecology.

That means that any robot deployed in the environment must be continually tracked and, once it has reached the end of its useable life, must be recovered, dismantled, and made safe. But there is also the risk that the robot will be irrecoverable with consequent damage to the eco-system.

Now one might think that there's not a lot that can be done about this. After all, the computers, power sources and imagers used in such robotic devices are all man-made, and many of them are composed of some pretty toxic substances. And there doesn’t appear to be any alternative to using them.

But apparently, the academic folks at the University of Bristol (Bristol, UK) think differently. They believe that it might be possible to build robots that decompose once they have reached the end of their mission. While it all might sound a bit far-fetched, the idea has won Dr. Jonathan Rossiter, Senior Lecturer in the University of Bristol’s Department of Engineering Mathematics, a two-year grant of over £200,000 from the Leverhulme Trust (London, UK) to work on developing robots that rot.

That's right. Dr. Rossiter, together with Dr. Ioannis Ieropoulos, Senior Research Fellow at the Department of Engineering, Design and Mathematics at the University of the West of England (UWE, Bristol, UK), aim to show that autonomous soft robotic artificial organisms can exhibit an important characteristic of biological organisms -- graceful decomposition after death.

Since there will no longer be the need to track and then recover such robots, the deployment of large numbers of biodegradable robots in the environment will become inherently safe. Hundreds or thousands of robots could therefore potentially be deployed, safe in the knowledge that there will be no environmental impact.

Now I'm sure that there are some among you who believe that Dr. Rossiter plans are all a bit pie in the sky. But I'm not one of them. This year, for example, we have already seen the development of micro lens arrays produced by a mineral precipitation by researchers at the Max Planck Institute of Colloids and Interfaces (Potsdam, Germany).

Nevertheless, I'm going to be very interested to see if and how those UK researchers can build an entire robot that is totally biodegradable. I guess we'll just have to wait a couple more years to find out.

As clear as daylight

This month, a leading engineering integrator of robotic and machine vision systems and a fastening technology company announced they had joined forces to introduce robotic capabilities uniquely engineered for a fastener installation press.

According to a statement issued on behalf of the two companies, the partnership 'provides an unprecedented marketplace opportunity for completely hands-off installation of self-clinching fasteners using the newly developed robotic system.'

The statement goes on to say, that 'the robotic system developed for the fastening technology company is equipped to pick up, move, and position a work piece for alignment with holes where fasteners will be installed automatically by the press. After fastener installation, the robot removes the finished work piece and advances to the next job.'

The system -- apparently -- is offered in two standard packages to accommodate various work piece sizes. The turnkey system integrates a conveyor with locator, output conveyor, gripper, robot, and a basic sequence program to interface with the press. Among available robot options, a robot slide can be supplied to expand work cells for multiple presses.

The robotic system sounds like a step in the right direction for both companies. However, there's only one slight hitch. When Vision Systems Design contacted the leading engineering integrator of robotic and machine vision systems to discover whether or not the system had incorporated any interesting vision systems, we were informed that the system had not been built yet.

Clearly then, this is yet another of those common instances where overeager companies and their public relations firms have forgotten how to use the future tense, leaving their customers somewhat disappointed that they cannot obtain a system that they may believe has already been completed.
