A 12 year old built the car and I checked it, seems correctly assembled. Uploaded the basic sketches to make sure the wheels turned.
Adjusted the Avoidance sketch from the CD for a different Pin and uploaded successfully (attached)
The car moves forward - stops at a an obstacle - looks around - backups up a bit and then just sits there looking around.
Any suggestions would be appreciated.
Thanks.
