Limpy the robot

“Limpy” is a “robot” that I came up with the other night.  I hate to even call it a robot, more of a remote-control abomination.  It’s what happens when one arbitrarily combines a remote control from a cheap toy, two Glade automatic air fresheners, and a pencil.  This little beastie took very little time and pretty basic tools to make, so it would probably be a good beginner project.  I think the only tools that you would really need are: a soldering iron, a set of screwdrivers, and a drill or drill-press.future robot body

I have taken apart both the air freshener, and the remote control device required in previous posts, so check those out if you want to build this.  One thing that I thought was cool about this little “robot”, was that it actually used part of the plastic air freshener housing as the robot’s body.  It always seemed a shame to buy these just for the internals and throw the rest away.

This was accomplished by laying it in the chassis and taping it down with electrical tape. Each motor output from the remote control was wired to each “leg” motor.  Both outputs were originally designed to run 3 VDC motors, so there didn’t seem to be any problem controlling the new motors.  This setup gave independent control of each motor to each axis on the remote control joysticks, allowing for independent limping around on both legs.

Not the most useful robot in the world, but an easy project to try.  For another interesting project involving an air freshener motor, check out this radial engine model that I made!
