Friday Build Update: 1/27/17

The FIRST season is almost halfway done and team 4611 is beginning to make important decisions on not only what we want to have on our competition robot but how we are going to make all of it work together within the maximum space and weight.

The drive team was able to test many prototypes today due to the time and hard work put into them by the fabrication team. They mounted the one wheel shooter and swivel platform onto a sled. We tested shooting it at different speeds (of the motor) and also putting balls into the shooter at different speeds. Side to side aim was very consistent, but up and down distance was not. Sometimes the ball would arch into the boiler, but sometimes it would shoot lower.

On another one of our sleds, mentors and fabricators worked together to cut out a part of the chassis to fit a more permanent and stable version of a ball intake prototype. They also added a cardboard hopper to the back of it, where the balls will go when collected.

Pneumatic mechanisms were attached to the gear holding prototype on Margo. Pneumatics will be used to push the gear out of the robot and onto the peg at competition. The drive team was able to test it at the end of the day today. Human players slid gears down the loading station at different speeds and tested how long it took the robot to get to the other side of the field and place the gear on the hook. Although inconsistent, the mechanisms worked! Gear Bot Video

Tests involving the field hoppers were also made today. We would like to be able to get half of the balls that come down from a hopper into our robot. Design team members tested how many we could get into a box, modeling our robot, at different locations. Where we will position our robot at competition depends on the volume size that we choose to make our final robot.

Electrical members soldered a piece of ultrasonic equipment for the programmers. Programmers are also working on visual acquisition and coding buttons for our shooter. We believe it would be easier for drivers to activate the shooter by pushing a button than using the joystick. This would minimize error and maximize the points we can get out of the time we have.
