Learning to walk, a tutorial on making bipeds walk

[Robert Lam] has produced a number of video tutorials, his latest being a tutorial on how to make a biped robot walk. He is mainly covering the individual motions and actions. He doesn’t go into any specific programming, but rather breaks down the act of walking into several motions and discusses the reason you need them as well as some variations. For some this will seem like obvious observations, but we’ve seen plenty of biped robots that attempt to walk without shifting their weight.You can watch this video after the break, but be sure to dig around in some of his other tutorials for plenty of good stuff.

Score online with robot soccer

robot-soccer

[Erik] and [Heni] have been using soccer as a way to improve code development techniques in robotics. Their soccer playing robots won first prize in the development competition at the 2007 RoboCup competition. They are using a teaching method they call Kinesthetic Bootstrapping to program the motions of the Bioloid robotic platform. The robots are moved by hand and those motions are recorded twenty times per second. The recorded data is then optimized in software and ready for playback in the robot.

After the break you’ll see a video of the robots playing soccer against each other. They receive commands from a computer via zig-bee with Nintendo Wii remotes as the user interface. That’s all fine and dandy, but perhaps you should try your own hand at a game. [Erik] and [Heni] developed a web interface that allows you to control the bots over the internet. We tried it out yesterday and had quite a bit of fun. We set the video stream to “Spectator” and “Jpeg Server Push” to get an image. You’ll have to wait until next week to play because the bots need someone to pick then up when they fall over. Live play is scheduled for Mondays and Wednesdays from 4-6pm GMT+2. That should give you plenty of time to program your Arduino to say “Gooooooooooaaaaaaaaaaaaaalllllllllll!!!” when you score. [Read more...]

Bioloid hacking with Johnny Lee

bioloid

Though we usually think of Wii projects when we see him, [Johnny Lee] is showing us some Bioloid fun. He’s decided to pick one up to play with, wanting to write his own control programs for it. Unfortunately what he found was that it doesn’t do wireless communication for control. Even after installing a bluetooth module, he found it was only used to trigger different predetermined motions. After some research, he found how to connect the bluetooth module to the main PC link which allows him direct control of the Bioloid via the PC. Unfortunately, the communication speed leaves a lot to be desired, but it’s a good start. We’ll keep our eye on this one.
