Robot Piloted by a Slime Mold

TeknoHog writes "Robotics researchers from the UK and Japan have linked up a slime mold to remotely control a six-legged robot. The mold, which is naturally light-sensitive, is able to hide the robot in dark corners, and the scientists expect to further this technology for use in smaller, autonomous units. There is also a preprint of the research paper available from the University of Southampton."

  1. Living brain controls flight simulator by Anonymous Coward · · Score: 5, Interesting

    Similar study last year. Experimental "brain" (25,000 living neurons, taken from a rat's brain and cultured inside a glass dish) interacts with an F-22 fighter jet flight simulator through a specially designed multi-electrode array and a desktop computer

  2. Biological sensors are and are not new... by zappepcs · · Score: 4, Interesting

    The news is that people are able to now work with them. Light sensors based on silicon and other materials simple take advantage of the light sensitive properties of the material. Using a biological material is no different, other than the need to 'feed' the sensor. As this story and experiment play out, there is no ready made practical application waiting for its development. The real advance here is working with biological sensors. Such work will hopefully lead to sensors that are sensitive enough to detect humans in the wreckage of a bombed building, or cancers (as some dogs can with smell) or other such sensitivities that simply don't seem possible with non-organic materials. This probably isn't going to lead to a bio-brain for robotics, but will make them much more sensitive in the sensor domain. Imagine if a robot could see or smell the way that some insects do? This would lead to robots that are much more capable, and much more useful for all sorts of dangerous work. Imagine a robot that works in water that can find even the tiniest of leaks on an oil tanker? Perhaps a robot that can sniff out drugs in cargo planes etc. The reason for sensors that are orders of magnitude better than what is available today goes without saying, more or less. This type of work will help make it more achievable, hopefully.

    Already, they are training bees (in minutes) to sense out things that takes months of training for dogs. This type of bio-sensor systems will hopefully make such work even easier to achieve. I can see that one day, a search and rescue helicopter can drop a truck load of independent water robots that seek out and locate humans in the middle of the ocean, saving lives by finding them faster than current methods, and bio-sensors may be the ticket to such advances.

    That's my take...

      Wouldn't such technologies suffer the same problems that people/animals face in hazardous/hostile environments?

      What happens when a bio-sensor based robot walks into a cloud of chlorine gas? (e.g. chemical plant explosion/fire).

      What about high-temperature environments?

      What about cold/icy ones (e.g. avalanche)?

      Radioactive areas? (e.g. dirty-bomb explosion)

      Biological agents (viruses, pollen, etc)?

      Wouldn't it also be difficult to maintain live cells in a machine? (e.g. what about food, water, oxygen, etc)?

      Cockroaches are immune to the effects of radiation, unlike most microprocessors. Using a cockroach to control a robot means you can use much chunkier (physically), and therefore more radiation-resistant electronics because they don't have to do any 'thinking'.

      Can't think of a use right now, but a trained cockroach perhaps?

  3. Re:is there some reason that... by nick_davison · · Score: 3, Interesting

    a photocapacitor or some other light sensitive electronics wouldn't suffice?

    Simple:

    "Robot controlled by light sensitive electronics seeks corner" gets a quick nod before someone realises eight year olds have been doing it with the basic Lego Mindstorms kit for years.

    "Slime mold remotely controls six legged robot" gets the quirky and weird headlines. Quirky and weird headlines can be claimed as public interest. Public interest can be parlayed in to additional funding for your otherwise unfundable project.

    So, whilst it's not really any more exciting, it does get the trivia audience - which gets the funding. Thus, for PhDs who can't get Google to hire them, it's essential to use a cockroach or slime mold or something similarly quirky to keep you in tweed jackets and leather elbow patches.

    A Dalek would work. I was moreso thinking Kang from the TMNT series(I think in the original comics the "kang" race were good guys). Ie that brain-shaped creature inside the big humanoid robot body to walk around in.
