System
Team 2177
Basics of Electrical Systems
• Components
• Custom Circuits
• Design
Components
• cRIO (brain)
• Digital Side Car (spinal cord)
Motor Controllers
• Speed Controllers (muscles)
• Relays (muscles)

Speed Controllers
• How do you choose?
• Linearity (great for drive train, possibly not needed for other items)
• Size (smaller is always better)
• Control (direct sensor feedback can be very useful)
• What do you have in stock?
Relays• Spike
• No variable speed control
• Small footprint
• 20 Amp Limiting
• Factors into motor choice
components
• Fans (sweat glands)
• Battery (heart)
• Radio (mouth)
• Converter (lungs)
Components
• Power distribution board (circulatory system)
• Everything plugs into power distribution board
components
• Wiring (nerves)• power wires (blood vessels)
• 40 Amp -> 12 gauge
• 30 Amp -> 14 gauge
• 20 Amp -> 18 gauge
• signal wires (nerves)
Sensors
• Provide feedback• Encoders
• Potentiometers
• Limit Switch
• Ultrasonic senor
• Accelerometer
Components
• Custom circuits• LEDs
• Teams with LEDs that lit up when they shot
• Camera
• Light up vision targets
• On-board computers
• Anything else you can think of!
Organization
• Wiring organization• color code
• number system
• zip ties
• tie downs
• power polls
Board Layout • How do we lay out our board?
• List all items on board and get all of them
• How much room you have for board?
• Where does the board go?
• Spacial constraints
• Lay out all components and their wire routes to make sure they all make sense
Thank You
• Thanks for coming! If you have any questions, feel free to ask them now!
