03/07:

We discovered that the aluminium profiles require a specific 20mm x 20mm aluminium bracket so the surface change of our 3d models have to be tweaked. The grooves on the back of the 20mm x 20mm aluminium bracket was measured and taken into consideration so it can fit on our 3d printed models

– Changed dev mode to 2

– Got the giga to control the motor (Pam too fast for motor)

– Got PCA9685 to control motor

– Tony suggested using PCA9685 to control all pins for DRV8874

04/07: We printed the 3D parts that connects the aluminium profiles on the side and the part that connects the wheels to the body (joint). We also printed the servo housing and legs We also that the 3D model of the differentiator is too big (40cm+) for the lab’s 3D printer as it can only print a dimension up to 20x20x20cm. As such we broke the differentiator model into 3 parts, using the tongue and groove method and screws to secure the pieces tightly together. We changes the 3D printed piece below the differentiator into an AP for more strength, it has its own 3D model design and print to connect those 2 pieces together.
