Trap Door and Electronics Box Work - Matt Mannino

With more items on our to-do-list left, we are finally finishing them one at a time.  We assembled a "trap door" for the hopper on the back of the robot.  This allows the balls to be dumped out from the hopper into the home station once its path is completed.

We also added some smaller features to the electronics box that protects and houses the electronics components.  There are two metal clasps, one on each side, that hold the box shut.  There is also a hinge that locks the box in place while it is open.

Drive Motor Configuration, Wiring, and Disc motor - Andrew Baden

Over the past few days, we have completed many of our remaining tasks to get the project completed by April 25th.  For starters, we finally have the correct motors in place for our drive train, and have the chains correctly laid out to the point that we shouldn't need to reconfigure them again.

We have also completed most of the major wiring to for devices such as the motors, motor controllers, battery, switches, indicator light, and the Arduino motor controller.

Now that we have the discs cut and hubs put on them, we can now finalize the mounting solution for them. The mount we used before was too flimsy, and was difficult to mount the motor to.  The mount we have now houses a compound gearbox because the motor we chose that would have enough power, runs too fast. This compound gearbox puts the discs spinning at an effective speed. The mount we have now also uses angle aluminum from the Gears Ed. kit to allow for a more stable platform, and reduce the flimsiness the previous mount had.

Over the next few days, I would like to finalize the hopper's position, and create the channeling plows on the front for the ball collector.
