Inside The Ugobe Pleo - Organic Robot Life - 0 views

  • CALEB CHUNG: Of course we could have used micro-servo motors to accomplish the motion of Pleo, but we aren’t able to use expensive motors. So we had to engineer it with a high-speed motor with high gearing and no backlash for control purposes and have it all fit within the muscle envelope of Pleo.
  • So what we did was go after a lot of ethology research. How do animals really handle the complexity of their environment? We built a virtual brain—a whole system that decides how Pleo will react in various situations.
  • CALEB CHUNG: Pleo will reset thresholds and adjust his idea of what he thinks is normal. Let’s say you get Pleo and you take him home to your shag carpet. When Pleo walks, the carpet will drag on his feet. So his force feedback sensors will realize that he is spending too much energy to walk around. Pleo will try different things to reduce the energy spent. Eventually, he will have the idea to step higher. Your Pleo compared to my Pleo will walk with a higher step.
  • ...8 more annotations...
  • Eventually, we got to the point where we don’t know what Pleo will do next because he learns. If Caleb and I went to your house to see your Pleo, we couldn’t predict a lot of the things he would do, even though we know everything we put in him. Pleo has the ability to change and figure things out on his own.
  • Consumers will be able to download and customize Pleo later this year or early next year. We want to give the user the ability to change Pleo’s personality, animations and tricks. We also want to allow developers and hobbyists to take the SDK and motion system and behavior system and choreograph advanced features and animations for new AI functionality.
  • We didn’t include a camera (or voice recognition) in Pleo because of the price point for the product. Pleo is probably a good hack for a CMU camera, and we want people to develop these sorts of things.
  • The only way you can create life is to give it choice. Life is very complex, and it has to evolve, otherwise it is a robot. The only way to get complex systems to work is to let them chose for themselves.

    Pleo is UGOBE's first designer Life Form and is based on the Camarasaurus dinosaur. He is made up of an amazing array of sensors, motors  (14!), and distributed computing with an ARM-7 processor commanding it all.

  • Motor drivers are essentially little current amplifiers
  • the control signal is likely on the order of 10 mA, and the motor may require 100's of mA to make it turn

    There are several websites documenting the original Furby circuit board. I decided to replace the original circuit entirely and replace it with a PIC based controller.

    Three motor designs are much more able walkers with longer strides and very tall steps. They are also a huge jump in construction complexity from a two motor walker. Walker Ver3.0 is controlled by a six-neuron nervous net. I opted not to go with the 4 neu
