There are a lot of rough and protruding edges on the robot. Unless we file, we probably won't be able to pass inspection. Relisted on 2/26 below

A limit switch is no good if we can't attach wires to it. Make sure there is room for a wire and crimped-on connector. And there needs to be room to install and remove that connector.

Most limit switches use narrow connectors which are more difficult to get than the standard too-wide connectors. Using the correct size is important for fit and securely holding it in place.

Here are the current autonomous modes:

From the driver's point of view:

       
  • AutoRun - cross the baseline. This is the default command. This goes straight, no additional steering.
  • Robot on left, do switch - Only do switch if it's on your side. Otherwise, do AutoRun.
  • Robot on left, do scale - Only do scale if it's on your side. Otherwise, do AutoRun
  • Robot on left, do switch or scale - Only do if it's on your side. Switch has higher priority than Scale
  • Robot on left, do switch or scale - Only do if it's on your side. Scale has higher priority than Switch
  • Robot on right, do switch - Only do switch if it's on your side. Otherwise, do AutoRun.
  • Robot on right, do scale - Only do scale if it's on your side. Otherwise, do AutoRun
  • Robot on right, do switch or scale - Only do if it's on your side. Switch has higher priority than Scale
  • Robot on right, do switch or scale - Only do if it's on your side. Scale has higher priority than Switch
  • Robot right of center, on right edge of the middle alliance station (adjacent to right alliance station) - go left or right depending on selection.
  • Do nothing.

We are flipping X (Exchange) and A (Switch) on the controller because it makes more sense to have the lowest position as A, which is the lowest button on the controller.

multi-wire cables like PWM or DIO must be inserted in the correct orientation. The cables we use are not physically keyed (unfortunately). The signal assignments are usually made so that reversing the cable doesn't cause any harm but it still won't work right.

Check before inserting. It only takes an extra few seconds.

When building a cable, a heat gun was used to melt & shrink a one-piece connector connector. The heat did its job but it also heated the insulation of the wires a little further away from the joint. Two adjacent wires got so hot their insulation melted and the conductors inside shorted. From the outside, it looked good (of not a little shiny from the partially melted plastic), but inside there was a short.

After making a cable, we should test them for continuity and shorts.
