In the latest issue of MAKE, Volume 27, the always-awesome Howtoons project column shows you how to build a wobbly little walker using two servomotors and some plastic coat hanger hooks for eccentric wheegs. While this is not really a robot, it’s a fun project for teaching kids some bot basics, like the important robot-building technique of hacking servos for continuous rotation and using Tupperware as a bot body (very handy). Here’s a free PDF download of the two-page spread from the magazine.

    Why not skip a step and just use DC motors by themselves, rather than spend money on a servo just to simply rip it apart?

    1. Anonymous says:

      Because you’d likely want to gear the motors and a servo sans electronics is basically a gearmotor. And servos are now pretty cheap, and you can get them sans control electronics, which basically makes it a gearmotor right out of the box.

  2. It doesnt really say you have to remove the end stops in the servo first, just running a non modded servo without doing that will most likely break a gear or two.

    I’m disappointed.  I thought this was going to be an article about how to make a center finding device for the lathe and drill press.
