2018:Electrical Main

Insert details/designs/drawings/info/notes relevant to overall electrical systems here....

To do:

- find gyros

- find cameras

- test cube sensors- complete

• tested sm312fvqd and found that 3 inches is the optimal close range. 
  • worked with the gripper/ hand group and they are working on mounting sensor
  • gain trim pot
  • selectable mode (Dark On/Light On)
  • it requires 2-3 inches of depth adjustability
• tested EE-SPY415 sensor
  • No adjustment
  • No built in LED indicator
  • small package
  • <1" fixed sensor
• tested 42EF-D1MNAK-A2 Allen Bradley Sensor
  • 0" -> 10" range of depth adjustibility
  • gain trim pot

- ramp sensors

- arm limits?

Pneumatics Sources

• Air Tanks:
  • Coast Pneumatics - cheap plastic cartridges, multiple sizes from 150-600 ml, roughly $13
  • Andymark - Clippard and unbranded seemingly similar to coastpneumatics products, $14-$17 for ~500ml
• Possible Solenoids - need closer review still:
  • SMC SY3240-6 family - what we've always used in the past:
    • Automation Distribution
    • Motion Industries
    • VeX
  • Bimba / Pneumadyne
  • NITRA from Automation Direct
  • Mindman from Coast Pneumatics
  • Andymark has Mead brand
  • Explanation of various types of solenoids - they sell some too but they seem to be unsuitable for our application, but their explanation of how they work is pretty great!
• Relief Valve:
  • Andymark - Norgren kit valve, $40
  • McMaster - McMaster part 48435K714 is recommended in manual. $5.50 MAKE SURE TO ORDER 125PSI VERSION
• Regulator:
• Andymark - Norgren kit recommended regulator, $28
• KleenRite has Norgren kit regulator for $17
