After learning basic skills about electrical, such as stripping and crimping wires, Timmy followed the Power Distribution Diagram to form the electrical board. He then assembled the power distribution block and branched out the 6AWG wire to main electrical components such as the circuit breaker panels, battery, Victor speed controllers, and robot controller. He then tested the connections and found that a fuse was clicking, because of a wire polarity issue, which was soon resolved. Then he started working with RJ to connect the components to the computer to load the program and test for issues. During this week, Krystina and Jason joined the electrical sub-team and they learned how to strip and crimp wires and connect components. The electrical team then secured all components down onto a square of plywood using screws.
On Sunday, Timmy worked with RJ to resolve the issue regarding the direction of travel. The wheel system was moving in inverse directions and after trial and error of swapping wires on the robot controller, the wheels were finally spinning the correct way
On Monday, the electrical team measured the space of availabe chassis space for electrical components and then cut out a metal board. We will later transfer the electrical components onto that board.
On Tuesday, the electrical team had no immediate work to get done so we were assigned to learn and set up the pneumatics. We fitted tubing, connectors, gauges, and a cylinder to the compressor. An incident occured with one of the cylinders resulting in a brass piece getting stuck in the treading of the cylinder, which has yet to be resolved
From Wednesday to Friday, the electrical team readjusted the components to fit under the CIM motors.
February 3 - February 9
On Sunday and Monday, the electrical team began transferring the components from the wooden board to the sheet metal board.
On Tuesday, the electrical team finished the tedious task of transferring all components to the metal board and secured the components using nylon lock nuts.
On Wednesday, Mr. Jimmy Miller brought back our cylinder, and it was like new. Many thanks to him and Mr. Denny. Having the second cylinder we decided being programmed was in the default code, the compressor worked like a charm. We used it to inflate the trackball to see how big it was.
On Thursday to Saturday, the electrical team finally secured the electrical board onto the chassis. The task was very time consuming because holes did not line up and we had to make additional supporting brackets. We also received our pneumatic actuators in the mail and then attached those except they are still not operational due to programming difficulties.
February 10 - February 16
On Sunday to Tuesday, the electrical team, as well as Spencer added the battery to the front end of the chassis by adding L shaped supporting brackets and using the extremely long reusable tie strap.
We also assembled the single action SMC solenoids and double action SMC solenoids, which are used to control airflow to extend or retract the cylinders. On Tuesday, Felix helped RJ to program the solenoids to retract or extend with the push of a button.
