Car Frame 2 (Robot car experimenting)

Penlight version. This design is the frame of a robot car, which can be used for experiments. The foto's should give an impression of the used motors, wheels and IR sensors and HC04 distance sensors. This is the very common hardware which you can buy everywhere. The battery pack which fits this frame is a holder for 4x Penlight AA.

The four holes in front of the battery holder is meant to mount your experiment print with the controller of your liking. I use a Arduino Nano to control the motors and sensors.
