Cool four-legged walking robot controlled by Wii Nunchucks

By andy

Check out this little fellow, a “walking machine” (he/she/it doesn’t have a name) designed, built and in ongoing development by Drew.

“Created for entertainment purposes. It is made to dance and entertain people at conventions and parties.”

It’s a radially symmetrical four-legged robot that’s operated from two modified Wii Nunchucks. It has taken two years of “hobby” time to get to this point and probably cost around $1,000 in parts/replacements.

It’s made from some custom-cut steel plate, copper, aluminum tubing, brass, a 7.4V 1100mAh lithium-polymer battery, a pair of XBee radio modules for communication (has a range of around 20 feet), Pololu micro SSC board and eight HX12K servos.

I’d kind of hoped that the robot had some of its own sensors on board so that it would avoid objects, but to be honest the level of control Drew has over it makes up for that. Next project perhaps?
