Summary

Walker I

 

    <h3></h3>

Walker I - a walking, turning robot. This robot walks until a touch sensor is pushed (like on a bumper). It then plays a sound, backs up until the outer leg is off the ground, which triggers a touch sensor, and then turns by rotating the inner leg. Then it walks forward until it bumps something again, repeating the process.

The cad file has some parts not aligned quite right - it was my first time using MLCAD and I didn't notice the misalignment. The next robot will have a better cad file.
