Jake posted up an Instructable for our mousebot “Mousebot from Make vol 2 is a fun introduction to robotics. So fun that I’ve created this expanded documentation of a Mousey build from start to finish, with a few extra little tips you won’t find in the mag. This how-to is best understood after reading the original article from page 100 of Make vol 2 however it is probably not required. Mousebot is a simple bot that uses two “eyes” to sense light and then turns towards the light. A single large “whisker” is mounted on the front of the mouse to detect collisions.” Link.
