Facilitating Robot Learning - 0 views

  •  
    In our own work, we pursue an experimental approach in two highly uncertain, dynamic, and high-dimensional domains: multi-robot learning, and learning by imitation. Both force us to deal with perceptual and action uncertainty, non-stationarity, and real-t

Intermediate Robot Building - 0 views

  • This book provides far more detail on the hardware aspects of robot building than any other I have seen to date and is worth picking up.
  • "Intermediate Robot Building" offers the kind of real-world knowledge that only an experienced robot builder can offer--the kind of knowledge beginners usually have to learn through mistakes. In this book, you'll learn the value of a robot heartbeat and the purpose of the wavy lines in photocells.
  •  
    Intermediate Robot Building by David Cook covers all aspects of robot building, from mechanical, to electronics, to microcontroller selection.

How I Got Over My Cheating Husband - 4 views

When I learned that my hubby was cheating on me, I was so angry that if looks could kill he would be already lying lifeless on the floor. But then, when I took a time off, I felt insecure. I knew t...

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.
  • 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.
  • 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.
  •  
    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.

Behavior-Based Control: A Brief Primer - 0 views

  • Note that behaviors themselves can have state, and can form representations when networked together. Thus, unlike reactive systems, behavior-based systems are not limited in their expressive and learning capabilities.
  •  
    Behavior-based controllers consist of a collection of behaviors. Behaviors are processes or control laws that achieve and/or maintain goals.

Basis Behaviors - 0 views

  • The basis behavior set of a system provides elements that are not further reducible to each other and that, when composed by sequential or concurrent execution, produce the complete behavior repertoire for the system.
  • Such basis behaviors are constructed, learned, or evolved from stable, robust interaction dynamics between the agent/robot and its environment, and serve as a substrate for the system's more complex behaviors.
  • My work generalized the notion of basis behaviors to multi-robot interactions, and demonstrated how a small set of basis behaviors per robot can be used to demonstrate a rich repertoire of individual and group-level behaviors, including following, flocking, homing, herding, aggregation, dispersion, and formations.
  •  
    In 1991 I introduced the notion of basis behaviors, a means for facilitating principled behavior synthesis and analysis in behavior-based systems.
