AV Work Day
Date: 5.25.16Location: Logan HS
Time: 9:44-11:15 AM and 4:00-7:30 PM
Students: DE Class and then after school Oscar and Grant
Goal: Test forward and reverse on main motor drive along with front steering control.
This was a breakthrough day for us. We were able to configure the controller and the motor driver to move the linear actuator for steering. We also tested forward and reverse on the main drive. It has been about a month and a half of bench testing. Finally being able to take off components we have built and start to mount them on the actual vehicle was a good feeling for the kids.
We had a problem with one of the computer cables we scavenged from some old PC’s. One of the pinouts we were using for direction on the front steering must have had a broken wire in it because our steering was not responding the way we would have liked. Troubleshooting took quite a while to detect it.
After the bench test, we moved all the components to the vehicle. Grant made another box for the steering interface and Oscar remounted the main motor driver which needed to be moved so we could access the chain guard.
Our next goal is to mount all components and then do a systems test next Tuesday. Still looking at an end of school completion date.

| I know...it is just a piece of plywood but this was what we used for bench testing. All the components have been removed and assembled onto the vehicle so it is good to see it blank. |
