R/C ARACHNOID BARBIE STROGG

Meet Barbie Strogg, a tortured doll found in the garbage. I cut her arms and body below the waist, and replaced the limbs with cybernetics: Her arms are plasma guns, and she walks thanks to six R/C controlled arachnoid legs. Now, she's rabid and hungry for blood!!!

Yes, too much "Mortal Kombat" is perjudicial for the health :-)

The reused materials:

Plastic case
Plastic pieces of your choice

For the legs:

For the electromechanics:

2 small electric screwdrivers

You will need nuts and bolts, spray paint and wires. Some epoxic will be required.

Tools: the usual. Dremel, screwdrivers, pliers and soldering iron.

The electromechanics:

Our fellow maker Rpantaleo have a great CAD image of the basic mechanics of a six legged robot:

I used a R/C from an old toy vehicle. You will need the kind of toy R/C how moves like a battle tank (you know: two motors, one beside the other. For turning, one of the motors spins faster than the other). For more torque, I replaced the toy motors for small electric screwdrivers.
