Thank you for the video Tyler!

Not presented in this video, but what if I tell you that we “developed” this season a 1gr (0.002lbs) mechanical arm braking mechanism?
In the picture above you can see a red gaffer tape that hold a zip-tie that rests between two gears of our climber arm.
In order to release the lock, we spin the motor to the reverse direction. That causes the zip-tie to fall.
We have a software precaution that detect if the arm changes its homing position (aka the zip-tie fell) and then hold it back in closed-loop, but during all competitions this line of code hadn’t need to been run even once.
(The only reason for the gaffer tape is to re-use the same zip-tie over and over, and avoid a fall of the zip-tie to the field).
