This weekend I finally convinced Jules that we should take his robot apart. Admittedly, he might have been less enthusiastic if Agent Bingo didn’t already need surgery — one of the DC motors in her legs had stopped working, so the poor thing could only walk around in circles. “Don’t worry,” I promised, “We can fix this.”

If only he knew that my idea of “fix” was a brain transplant…

With the shell open, and Jules starting to get bored, I sketched out what I thought was our best option:

  • resolder her leg motor (!!)
  • take everything out of her cybernetic skull: controller board, “eyes”, IR sensor.
  • leave her body mechanics alone (it’s a hard plastic gearbox surrounding a single DC motor, which makes her arms and head move)
  • replace her controller with an Arduino, her eyes with ultrasonic distance sensors, and maybe a display on her chest

So I’ve ordered the parts, but still haven’t resoldered the poor ‘bots leg — tonight I’ll do that, reassemble her in her “original” condition/capability-matrix, and let my son have his toy back.

For a little while.
