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...

5star anti-interference electronics motor noise

  • This is the 3 capacitor method.  I used this one in all my RC cars and many of the RC toys that I have taken apart use this method.
  • One of the easiest and most overlooked technique that can be done to lower motor noise is the twist your motor and motor power wires.  This in affect forces the magnetic fields to cancel each other out.
  • By placing a metal shield between your motors and radio can do wonders.  Also keep in mind that some metals shield better than others.   Carbon Steel shields several hundred times better than aluminum.  Dont use this shielding as a conductor or you may compound the problem.

  • Place your high current wires away from sensitive areas and antennas.  Don't run the wire parallel with wires that are used as signaling in your micro controller.  If you must its best to have them cross at 90 degrees.

    In the past when I built a Bot I would just slap it together and hope for the best. However when I started to use RC receivers to aid in the control of my bots the results left a lot to be desired.

mechanics robot tutorial wheel

shared by York Jong on 31 May 07 - Cached
  • Large diameter wheels give your robot low torque but high velocity. So if you already have a very strong motor, then you can use wheels with larger diameters.
  • But if your motor is weak (such as if it does not have any gearing), you want to use a much smaller diameter wheel. This will make your robot slower, but at least it has enough torque to go up a hill!
  • Wheel width. You do not want it too wide as it causes increased resistance to rotating the wheel on a surface.

  • Make sure you get a motor which already has a gear box attached, as it makes your robot much better controlled, more efficient, and stronger.

    This robot tutorial should help you with the mechanical aspect of building your very first robot. You should have already read my build your first robot tutorial before moving on to this tutorial.

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.

  • 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.

Basis Behaviors - 0 views

5star behavior-based delicious imported robot theory

shared by York Jong on 26 May 07 - Cached
  • 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.
