Introduction: R/C ARACHNOID BARBIE STROGG

About: I'm Mario Caicedo Langer (M.C. for short), a Colombian STEAM educator living in Azerbaijan, BSc in Naval Sciences, Master in Toy Design, and former Navy officer. I am a CAD and 3D Printing enthusiast and an ar…
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:

For the upper body:
  • Half Barbie
  • Various plasctic pieces (acoholometer mouth pieces, fax machine gears, etc)
For the lower body:
  • Cordless phone base
  • Plastic case
  • Plastic pieces of your choice
For the legs:
  • plastic compasses
  • pantograph
  • wipers
For the electromechanics:
  • R/C from a toy car
  • 2 small electric screwdrivers
  • 2 plastic wheels
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.
