In addition to the solenoid that we had to order for the most critical module, we purchased 1/4'' aluminum plate for the body. We also plan on ordering chains for driving the wheels, as well as bearings to keep them in place.
We encountered a few problems throughout this process including aligning the motors properly with the shafts, and designing the sprockets to stay within our budget and to be made out of material provided in the kit. Since the motors were not tall enough to align with the shafts, we decided to cut out sections in the bottom of the main plate, or body, that could fit blocks made of 3/8'' aluminum square stock that would elevate the motor to the proper height (shown below). We also decided to make the sprockets out of 1/4'' aluminum plate that is provided by the kit, in order to stay within our budget. Besides these minor problems, the project is going smoothly. We plan on manufacturing the remaining parts and assembling them into our final machine by the middle of next week.
