I'm not proud of the design of this. It's rather ugly. But I thought I'd still upload it to see if it could inspire someone else to make a nicer version. I hope maybe someone find the simplicity of it quite cute. It's a common design of a 4 servo biped walker. It can be controlled with an RF remote, an Arduino, an MSP430 Launchpad or similar. It walks, dances... well moves around. I've posted a video here:http://lars.roland.bz/2011/09/08/3d-printed-simple-biped-with-4-servos/I haven't included an upper body yet. I'm just using a Lego plate on the video, but I'm planning to build a proper body for it. I thought I might add some arms and some mini-servos to control those also... Glue 4 servos (two into each leg), as shown on the picture. Attach the foot to the lower servo using screws. The servos are from HobbyKing, but you can of course use any other standard ones.
