When Insecure is put down in an open area, the right wheel only will be moving forward, and the NeuroBuggy will be driving in counterclockwise circles.
If it is put down with a wall on its left however, the NeuroBuggy will move forward and left, bumping into the wall.
This will activate the Touch Sensory Neuron on the left front of NeuroBuggy, which will activate the left Motor Neuron, and cause the left wheel to rotate forward. This will move the NeuroBuggy slightly away from the wall, deactivating the Touch Sensory Neuron, and the cycle begins again.
