2015:Electrical Controls Subteam

Design

Driver #1's side of controls will be able to slide to the right and cover the laptop. This provides for narrow controls for transport. This will have a lock to is doesn't accidentally slide apart during transport.

The intent is to have a simple release mechanism.

Handles on each end for carrying.

2 joysticks for driver #1

• Y-axis: move robot forward/backwards
• X-axis: move robot left/right
• trigger: shift?
• button 2: lower center wheel

1 joystick for driver #2

• Y-axis: move lower grip up/down; controls speed of movement
• trigger: pulled means lower grips are closed (if needed, flip broken switch which means click trigger to close)
• trigger: released means lower grips are open (if needed. flip broken switch which means click button 2 to open)
• button 4: close upper grips
• button 5: open upper grips
• button 3: possibly use for 'level 3' preset, so tote is high enough to put on top of 2 totes created by human player
• button 6 (or 8): pull RC grabber back in
• button 7 (or 9): release RC grabber to get can
• button 6/7: could be used for presets (means 8/9 used for RC grabber)

N broken switches

1 3-way toggle for autonomous

• up: a pre-picked auto-mode
• center: no auto
• down: use auto-mode that is selected on SmartDashboard

Future Use

• 3-way toggle for future use (maybe picking which driver opens/closes grips)
• TBD

Laptop for Dashboard

To do

• Find data sheets and parts: 3 position switches, broken switches, handles
• Sheet metal drawings for boxes
• Determine which board to use for the joystick interface
• Lights?

Research latching mechanism

• Use something similar to a gate latch

• Pin/bolt attached to movable part/left section
• create a latch similar to: http://penfieldrobotics.com/wiki/images/5/53/Lock_and_Pin_%28paint%29.png
• 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

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