Sunday Update: 2/19/2017

There are only 2 more days left until stop build day. The team is finishing up it’s competition robot. 

To bring the weight down, fabricators cut holes in the gear grabber, wheel shooter and frame. We won’t be able to put a wall in front of the side pneumatics pieces, as it will put us above the weight limit. However, a wall protecting the the electronics was mounted onto the other side of the robot. An ultrasonic sensor was also placed onto the frame of the robot, using a 3D printed mount that the drafting team made. Red and black tape was added to the middle so drivers can recognize their position when picking up and dropping off gears. Strip LED lights were mounted onto the top of the frame and will be used with the ultrasonic sensor to signal to drivers when they are in range to shoot balls or drop off gears. Modifications were made to the shooter before driving the robot.

First, the drive team tested the ball collector to find the angle in which the plexiglass ball deflector needed to go to push balls into the hopper correctly. They also tested picking up and dropping off gears. In order to push the gear onto the peg, the drivers turn on the ball collector. The ultrasonic sensor worked with the LED strip lights; the lights changed color based on how far the robot was away from the plexiglass. Speed modifications were made to the shooter and ball collector. At first, balls from the shooter were not getting to the height we needed, but after some coding modifications the robot was able to shoot balls into the boiler consistently.

Other fabricators are finishing up making bumpers for the competition robot.

Electrical team members worked on wiring ultrasonic sensors so we have more of them for programmers to test and play with. One sensor was added to the prototype robot so the drive team can practice with it in between stop build day and competition. New motors were put on it as well.

Electrical and coding team members continue to fix and test code on the mecanum robot.
