2015:Electrical Controls Subteam

Design

To provide for narrower controls for transport, driver #1's side of controls (i.e. 2 joysticks) will slide to the right and cover the laptop. These will automatically lock.

The intent is to have a simple release mechanism. When released a gas strut will automatically open the controls.

• 2 joysticks for main driver
• 1 joystick for aux driver
• 1 3-way toggle for autonomous (up=a pre-picked auto-mode; center=no auto; down=use auto-mode that is selected on Dashboard)
• 8 broken switches
• Laptop for Dashboard

To do

Not yet started

• Find data sheets and parts: Handles
• Lights?

Started but Needs Work

• Sheet metal drawings for boxes
• Sheet metal drawing for right top
  • Need to finish lightning bolt, add 1/32" allowance around the bolt
  • Update broken switches with square cutouts per the new switches
  • Update three-way switch hole as required per the selected part
  • Add cutout for Ethernet port on the upper left corner of this part? It's the round part in the box of parts.

  Research latching mechanism

  • Use something similar to a gate latch

    • Pin/bolt attached to movable part/left section
    • create a latch similar to: <a href="http://penfieldrobotics.com/wiki/images/5/53/Lock_and_Pin_(paint).png">http://penfieldrobotics.com/wiki/images/5/53/Lock_and_Pin_%28paint%29.png</a>
    • one latch mounted to front of fixed section and one latch at the back
    • run a u-shpaed bar from latch to latch (under the secondary controls)
    • have access to bar via a hole through the secondary controls lid
    • gas shock is TBD

    Ethernet port location

    • The option below needs to pulled from both sides, but we want to be able to pull from one side only

      Power cable

      • The options below need to pulled from both sides, but we want to be able to pull from one side only.

        • Our only remaining idea is to use the retractable cord mechanism from the iron and insert our own cords (ethernet, power).

        • If we were to proceed with the iron idea we would need:
          • 2 irons (one for ethernet, one for power)
          • a power cord
          • a flat ethernet cable
          • a way to release the cord and allow it to retract

Completed 

Determine which board to use for the joystick interface

• Cypress is mostly a USB-Serial and PSoC test board, it doesn't really have what we need.
• LaunchPad has digital and analog inputs. There are built-in pull down resistors, so wiring switches will be easy. There are sample programs including joysticks already setup to use with the Dashboard; the source code is available so it can be modified. Also, form factor is much better for using the contorls.
