TARS from "Interstellar"

If you haven't seen it yet, the new Christopher Nolan film "Interstellar" features three robots that look like a cross between HAL and a ninja throwing star. _1412189530.jpg They're pretty clumsy puppets.

Obstructions on the field

Hello LMRians,

A week from now, a huge covered hall will be overtaken by an army of robots - over 60. My robots will basically be a bluetooth controlled robot and a transmitter (2.4GHz) controlled robot.

There will be other robots running on Bluetooth, Wifi, RF Modules, etc. I am curious about the major obstructions (frequency variations, data collisions, etc.) among/between robots,

I'm working on a project for a robotic (duh, right?) arm with a minimum of 6 DOF and needs (would prefer) to support a max load weight of about approximately 50 lbs, when fully extended to a length of about 2 meters/6ft, give or take depending on the final hardware selection.
