2 & 3/8: Receive of PCB and soldering of it was done. 3D designing and printing of motor + servo housing to give it more support and make it longer so that it can navigate over rockier terrains. All of the motor was wired up and attached to PCB, and is able to run!
4/8: The hinge used to connect the legs have too much rotational force on it due to the compression on the metal hinge which causes the legs to bent in an outward angle when the wheels are rotating. We tried to use spacers such as nuts and washers to reduce the compression but it was ineffective. As such, further exploration on the types of hinges are available needs to be done to remove or reduce the rotational force.
