This was done by Out-of-Plane Labs as a demo project for our Pegasus servo controller (you can just barely see the board underneath the mass of cables in the top center of the picture). The Pegasus provided commands to the 8 servos making up the legs (2 each) and was connected to an Xbee wireless module for communication with the user controller. The second picture is all of the spider's body pieces pre-assembly. All of the design and manufacturing was done by Out-of-Plane Labs.
One of the eventual goals for this project was to add an accelerometer for gravity sensing - if the spider was flipped on it's back, it should be able to sense that and flip the legs down in order to continue moving.
Enjoy this project?
