Many of the WowWee robots are ideal for hacking. The RoboSapien Version 1.0 is very complex inside and simple at the same time. Doing a simple motor and switch count though yeilds 9 Motors and 8 Switches. Assuming you want both forward and reverse on each motor you would need on the order or 26 digital/analog IO pins.
So a “Wedge” implementation seemed the best choice. The concept of the software “Wedge” has been around for a while. Basically it is a program that does nothing most of the time but then can be activated on a special sequence. Wedges have other names like hooks (as in Kernel Hooks), Terminate and Stay Resident, or call back. This approach allows me to still use the RoboSapien as normal but also take complete control…
And here’s a couple video of other hacks…
These bots are super cheap now and fun to hack.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
