Challenges That Need Solutions

When I built Mark 1, there were only three problems. Firstly the wheels were falling out and they were not aligned.

So to solve that I used many axle bushings to prevent my wheels from sliding along the axle.

For the alignment, I used my line of sight and math to align the wheels.

But there is still the final problem which is that the clearance under the brick (i.e. the distance from the bottom of the car to the floor) was only about a cm.So to increase the clearance, I flipped the brick around so that the buttons will be at the bottom and there is more clearance.
