Build electronics test harness #11

Closed rhauch closed 10 years ago

rhauch commented 10 years ago

If we install all of the electronics (except for the battery) on removable boards (e.g., plexiglass), then the electronics can be assembled on a workbench before the mechanical work has been completed. Additionally, such an "electronics chassis" could actually be used by the programming team on a workbench, without needing to deal with the mechanical aspects.

But for this to work, we should have a test harness to which we can connect the various motors controllers (and other output controllers) so that we can (a) test the electronics, and (b) test the programming. For example, we might connect the wires from each motor controller on the electronic chassis to a light on the test harness.

The test harness should be on a board for easy transport and to keep wiring organized.

There are two ways to do this: 1) Use the disabled mode from the driver station -- runs all the code, sensors, but doesn't run motors. Easy! 2) Hook 24 VDC light(s) to Talon's. One light goes bright both directions, two lights w/diodes would light one way vs. the other. I have 24VDC stack light we can try...

For 2, should still drop breaker size to motors to be safe.

If we build the removable electronics board(s), then the only thing we need is some standin for the motors.

This Autodesk library is a library for Autodesk Inventor if you need it.

We didn't really do this for competition, so closing. (For post-season activities, we should create new issues under our main GitHub repository).
