R.O.B has three motors to control his movements. He was instructed to move based on commands flashed onto a CRT (tube) television. Those commands are not documented and we don’t have an old TV to cart around so we’ll be looking to hack the circuit board or just hack the DC motors directly. The driver ICs are Sharp IR2C25 and the TV receiver is Nintendo RFC-CPU10.
We’ll be scouring the Interwebs for information. Schematics seem elusive. There are some hacks but not alot of documentation – links to other R.O.B. hacks are in the previous post.
If you want to follow along, post in the comments!
And don’t spread the news too much, so the prices on eBay don’t skyrocket, shhhhh.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Battery – Red and Black
Spin – Yellow and White
Claws – Red and Brown
Up/Down – Orange and Yellow
this leaves blue and green for the optical sensor
Oooops, blue/green on rainbow ribbon cable are probably a limit switch as there is a 4 conductor white ribbon cable from the board up through the center to the head. That cable: V=BAT, G=GND, S to RFC-CPU10 pin 1 (Guess light sensor), L through 1K ohm to RFC-CPU10 pin 4 (guess Red LED).
