Jaguars Natural Habitat
CAN ¡Sí, se puede!
Talons Hurt. At least when they scratch you.
Victors Its what we are!
Spike This isn’t Spock and they don’t hurt when you poke them.
Pretty graphs! Now all we need is an effective electrical system… right..? *Credit to team 1718 for graphs
Custom circuits A miscellaneous plethora of awesome stuff rendered under the principles of the art of circumlocution. • Teleportation Devices • Wibbly Wobbly Timey Wimey… Stuff. • Levitation • Flux Capacitors • Warp Drives (FTLs) • Imagination
Digital vs. Analog • If you would like me to explain the difference, just ask!
The Electrical CAD • Altium • Multisim • Ulitboard
The cRIO • The "Brains" • Modules • Digital Sidecar(s) • 4-slot vs. 8-slot
Modules • FIRST Legal • NI 9201 • NI 9403 • NI 9272 • Not FIRST Legal • NI 90210 • NI 3.14159
Digital Sidecars • Unlimited expandability • Realistically? • Sensor input • PWM output • Pneumatic Control
Which is better? 4-slot 8-slot 400 MHz 64 MB 128 MB Spartan-3 2000 930g 19-30V 2 Ethernet • 400 MHz • 128 MB • 256 MB • Spartan-6 LX45 • 643g • 9-30V • 1 Ethernet
Organization Are you ready to be scolded?
Board Horizontal vs. Vertical Left Side vs. Right Side Multi-level vs. Single Level Team 1713
Wire Organization Tools Power Polls Tie Downs Zip Ties Power vs. Signal Separation Wiring On/Off the Board Coding, and not the kind that makes the robot go McMaster-Carr PN 9284K411 (Expandable Mesh Sleeving)
2015 Control System It says CAN again
2015 Control System Please learn CAN.
