Figure 3. Motor Mounts2.2 PCB MountsIn the original design, the PCBs were to be mounted in layers using screws andspacers at each corner. However, after looking at the design carefully, we foundthis mounting method to be inconvenient in terms of accessing and debugging thePCBs. Therefore, we decided to switch to the wooden slots that we are currentlyusing. This mounting mechanism enables us to slide each of the layers in and outindividually for debugging. Just like the motors, the wooden PCB mounts areattached to the main body using an aluminum corner. (See Figure 4)Figure 4. PCB Mount2.3 BodyThe chassis body, as shown in Figure 5, is actually quite simple; it consists of a10cm x 10cm aluminum plate, two standing casters in the front, and two ball3
