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
