Exo Arm Work Night 5.12.17

Work Night
Date: 5.11.17
Location: Logan High School
Time: 3 hours (4-7:00)
Goal: Complete the wiring and begin building the E-Stop control circuit and delay.

Tonight we worked on completing running a different kind of conduit and pulling wires through it. This sounds easy on the surface, but we solder each wire connection in a grounded junction box, wire nut the connection and then use electrical tape over the wire nut to ensure it will not come unscrewed. The conduit is a new plastic flex conduit which protects our wiring running from the box looks surprisingly good on the arm.

Ben and Grant worked with Mr. Foye on two different circuits/boards that we needed. One to control the actuator and the other to allow the E-stop, relay and timer delay circuit to connect. This circuit is being soldered up after we tested it.

We are anxious for our next work night which will allow us to hopefully connect everything and test the system on the arm.
