The Breadboard Monster
The biggest design flaw on our OTV was having to attach the breadboard upside down on to the acrylic shelf instead of on to the chassis. This allowed the wires to fall out sometimes and made it harder to plug the wires back in to where they came from. We also couldn't detach our shelf after the breadboard was attached to the shelf because the sensors are attached to the other parts of the OTV and if we did, the wires would fall out. This created major difficulty in attaching more components onto the OTV after the application. This problem was created due to the lack of designing where all of the components on the chassis would have been placed. When we began building, the placement of the motor controllers interfered with the Arduino and breadboard. Because of this, we moved around the motor controllers and the Arduino to be able to fit onto the chassis but there was no room for the breadboard. Therefore it had to be moved upside down onto the acrylic shelf.
Fortunately, we were able to solve this issue (to some extent) by securing the wires as well as possible with electrical tape. While it is not the prettiest of fastening methods, it is permanent enough to keep the wires in while the OTV moves and completes our mission, it is not so permanent that we could not remove and replace any wire or component if something were to malfunction. Overall, we are just happy that we were able to quickly adapt and find a solution for our breadboard placement issue.
