YouTube user [onefivefour] posted a video of his hacked up toy robot hand. These cheap robot hands usually only use one wire to move all five fingers. [onefivefour] improved upon the design and added five servos to allow independent control of each digit.
The servos are controlled by a PICAXE microcontroller, and [onefivefour] is willing to share the code. A few pressure sensors in the fingertips would turn this build into a great test bed for future development. It would also be great for an [Anakin Skywalker] Halloween costume if anyone on the planet ever wanted that specific costume.
[onefivefour] says he only spent $6 on his and while there’s more money sunk into the servos, it was probably a good investment. We love seeing hacked up pieces of plastic like the fully functional Wall-E or the dancing Androids. If you’ve got a toy hack in the works, drop us a line on our tip form.
