1. Software

Changes

Several files were changed to cleanup unnecessary imports, and to attempt setting up arm pneumatics. The preliminary Auton1Command.java file for the first autonomous option was added.

2. Hardware

Summary

Advancements were made to the end effector. Its shooting capability was tested, and part of Aaron's 3D printed plastic disc broke off in a launch test. It flew along with the ball, proving that it couldn't handle the shock of the launcher piston when it reached the end of its motion. Therefore, changes will need to be made to the end effector.

Changes

The battery holder on the back of the robot was moved back an inch. A polycarbonate plate was placed over it to prevent the battery from bouncing upward when traversing obstacles. The second hook was made. The attachment mechanism was worked on.

Concerns

Hooks needs to be completed. A stronger and revised puncher disc is needed; perhaps a 3D printed plastic one will not be strong enough. The new end effector seems a little heavy. The pickup wheels have high friction for pickup but may hinder the shooting accuracy of the robot.
