Possessor

Sab-BOT-age has struggled over the possessor, without being able an effective device.

I would like to explore a completely different approach. Team 103 Cybersonics has an effective vacuum-type possessor. There are two units, left and right, allowing space for a central kicker. Vacuum is provided by two axial 3-blade propellers (L&R) each driven by an ungeared FisherPrice motor. Two rollers (L&R) within the vacuum plenum contact the ball, allowing it to roll on the floor while in possession.

With this possessor, we would not need such a wide kicker. It could be cut down.

A drawback is the need to position the ball into the central possessor by driving. Our current possessor does not center (or possess), but allows accurate kicking over a wide portion of the robot's width.

I will work first in Inventor to develop this concept for DEWBOT VI.

Mirror

Suggest we install a polymer mirror on the robot front to help us see and therefore clear balls hiding behind the bumps. We need to test the concept this week. I'll arrange materials & time.

Autonomous

Drive-train

Erratic drive-train behavior plagued us at Monty Madness. Appears to be a new problem. Cause?

Human Interface

Paul has added new drive capabilities, but these are underutilized (or unutilized) by the driver. Why?

• not useful capabilities?
• difficult (non-intuitive) control?
• inadequate training?
• complaicent driver?
• do I really need to buy an X-Box?

Gary Deaver replaced wheel treads and upgraded these to the "Dreaver" system. The tread on wheel 1 (Right Rear - also the only "Deaver Attachment" wheel at Monty) was polished smooth (but still securely on the wheel). See wheel photos below.
