Competition Season Meeting

Meeting Date Meeting Time Location Attendees
Monday, December 1, 2014 6pm - 9pm TCHS Brandywine Akhila, Nick, Brad, Laura, CJ, Trevor, Justin, Josh, Braden, Amal


Tasks Reflections
Milling
  • Josh worked with Justin, Andrew and Josh's grandfather in order to mill the elevator connecting bracket at amazing speeds of 1/8 inch per minute. Although the speed was quite fantastic the precision was exquisite.
  • Last meeting Justin milled a new part for the robot in plastic, then today was made in metal witch took a long time to mill. One cut took 7:42 to complete with is a very long time.
NXT Case
  • CJ worked on building a temporary case for the NXT. It was built in case the Autobots, another FTC team also based in TCHS Brandywine technical school, was not able to 3D print a NXT case in time for the competition Saturday. Holding the NXT from the top the Case would allow the team to slide the NXT easily in and out. Additionally because the case has only two sides to leave the USB and other ports free to be easily and efficiently plugged in.
Servo Mounting
  • First, Laura and Braden took of the large servo mounts, because we realized they were too close to the pistons, and would hit. We decided to replace them with the smaller servo mounts that had occupied the space previously.
  • Braden and Amal were mounting the servos during the meeting.
  • Amal was the one who screwed it in and Braden was the one holding the servo.
  • Amal got help from the great Mr. Scott Featherman on the servos because in the beginning we were one short of a servo.
  • We figured out a smart way to wire the electronics and secure the mounts.
Making Goal Guide Shorter
  • Laura worked to make the goal guide shorter so it did not rub on the ground.
  • She used one of her favorite tools, the dremel, to remove the excess plastic.
  • After she finished, multiple people starting noticing a strange smell. The mentor then determined Laura killed the motor in the dremel. It could no longer be of any use.
  • Laura found out she smoked the motor because she was cutting to slow. It was melting the plastic, instead of cutting it, and all the plastic buildup cause the motor to smoke.
Making the winch to raise/lower the linear slide
  • Laura and Trevor worked to make the winch for the linear slide. Trevor learned how to cut the spools on the lathe. They looked wonderful when he finished.
  • Then, we worked to broach the spools, and cut some shaft keys. Finally, the winch could be assembled.
  • Hopefully, next meeting we will be able to string up the linear slide, and raise/lower it.
