Building the force sensor attachment

1. Before we add the force sensor, the robot needs to be lifted up with wheels and the plastic caster ball element using the following steps:

2. To begin this process, connect a gray 3x5 H-shaped beam to the azure caster ball frame using two black connector pins:

3. On the top of these two elements, add a purple biscuit element using two blue connector pins:

4. This sub-model will attach to the underside of the robot body to the purple 7x11 open frame. This element is placed opposite to the color sensor:

5. Next, turn the sumobot back to the original position. You will add a wheel to each of the medium motors. Attach a wheel using two black connector pins and one yellow 3L axle:
