140. Forget to reconfigure the joysticks on the driver station after swapping c-RIOs right before a match.

141. Forget to tether the robot in the pits.
142. Leave the safety mode on while re-imaging the cRIO
143. Test the code while the robot is sitting on the table, with no blocks... *coughlorenzocoughcough*

The only thing that's holding your breakers in is friction. Usually the fit is tight enough to keep it in, but one good hit can knock one out.

144. Practice a 50 pt. climb and dump, which we had never tried before, at CMP on the half court practice fields 1 hr before queuing time. Without using belay hooks... our robot was a victim of the only tornado at CMP this year.

145. Forget to close the main pneumatic release valve.
146. Run 2 BB550s on 1 Victor due to a shortage of Victors
147. Decide not to strap in the battery because you need to be on the field.
148. Use 14 Clippard Air Tanks. Inspectors do not like this.

149. Spend an hour trying to design a custom direct drive gearbox using an 84 tooth Vex gear for a 4 inch wheel, then you realize the diameter of said gear is 4.3 inches.

149. Build a robot that takes 10 minutes to change batteries.
150. Use clear bakelite for a robot chassis bedpan (are mentor thinks it's plexi, it's not)

If this amount of stored pneumatic energy (just over 10 kJ) is released all at once (i.e. due to tank rupture), the resulting pressure wave can cause eardrum rupture anywhere within a ~5 ft radius.

Huh. Mr. Gregory was simply surprised by the sheer volume and then had to wait the full 6 minutes while we filled up.

151. Design and build turret without drive practice.
152. "Last-minute" code change.

153. Assume the soft limits on your Pizza Box are going to work the first time

Re: Things you only do ONCE!
 

154. Leave a space heater on in the programming area overnight.

155. Drill perforated sheet metal with a hand drill without clamping it down (cut the fingertip off of my finger).

156. Put a circular file into a drill press to simulate a lathe (it made about 2 revolutions, bent 30 degrees, spun 5 more times, then snapped off and flew across the shop. I never found it...).

157. Use a dremel to cut a hole bigger in a 2X6.

158. (non-robotics related) Try to rotate the square piece in Tetris.

159. Almost use up all of your team's bandaids...

I believe you mean camelCase every time

Re: Things you only do ONCE!
 

160. Build a 70" tall robot to fit under a 30" bar

NEVER AGAIN:ahh: :ahh:

161. When cubing joystick inputs to produce a smoother curve, mix up the inputs to the Pow() function so that you're raising 3 to the power to the joystick input rather than the joystick input to the power of 3.

The result, of course, is that a joystick input of 0 (not touching it) will result in a motor output of 1 (full speed ahead).

I'm sorry, Luke!

162. Test complex autonomous code that relies on gyro and vision during a qualification match. We tested all the individual components in the build room, so it'll just work, right?
