This is a 3D versión of BeetleBot by robomaniac.

The operation is very simple, as you can see in the electrical connection of the previous image, when you press the corresponding limit switch, you can change the direction of rotation of each motor. This way when, for example, if BichoBot collides with the left antenna (right side), the left motor rotates back and the right continues to rotate forward, getting the robot to turn on itself and change its path.

Material list:

2x 1,5V dc motor

2x Limit switch No-Nc

2x AAA

1x AAA battery holder

10x 2x10mm screws

Wire an tin.

To improve the slip of BichoBot, I recommend putting heat shrink around the "feet" and a piece of felt in the back as seen in the image.
For more fun, you can print several diameters of "feet" and go testing, with larger diameters get a higher speed and if you swap between feet, you can get circular trajectories.

For the 3d impression of the lower support, the antennas, the "feet" and the support of the motors, it is not necessary to print with quality, to activate supports or to put raft. However for the case, I recommend defining supports in Zigzag to 5% minimum and a 6mm raft to ensure a good impression.
