February 7, 2016 – Sunday Meeting Recap

Stop build day is fast approaching for team #4611. The big wheel catapult prototype is in the final stages of construction, the wheel shooter continues to be perfected, and plans are being made for the final robot by the design team.

On the big wheel catapult prototype, motors had to be wired to victors and PWM cables plugged into the roborio. Pneumatics were slightly moved in order to fit on the chassis. After the second half of the board was mounted onto it, electrical members attempted to attach the battery but found that it wouldn’t fit under a gear box and motor. Because of this, the board had to be cut so that the roborio rests under the gear box and the battery is attached further down. Also, fabricators added a line of metal underneath the other half of the board because it sagged down and would catch on defenses.

A group of fabricators had to move a gear box on the wheel shooter prototype because it was rubbing up against a chain and the electrical team fixed some poorly crimped ends. After a new battery was mounted on and the robot was tested it was found that the new intake worked tremendously better to pick up boulders and trap them.

Fabricators took measurements of the prototype to start making pool noodle bumpers. Another group began making the draw bridge and completed the chival de frise.

The design team plans to work with electrical members in the future to draw and CAD out a new board for the next big wheel shooter. 2 more victors will need to added for scaling.

Programmers coded an autonomous mode and visual acquisition on the new kangaroo computer by doing IP configuration for the roborio.
