 To think that one can "learn" engineering in 6 weeks while under the strain of building a robot too is proposterous. FIRST isn't about teaching. It's about inspiring.

Re: Attaching a standard car relay to the Digital sidecar
Spike = Spike relay module from IFI Robotics
http://www.ifirobotics.com/spike.shtml Easy to use, bulletproof relay for upwards of 20A at 12VDC with an optically-isolated input structure that's typically connected to something like the Relay Output lines from the sidecar. If you don't need a full 40A but 20A is sufficient, you might want to consider using a Spike. If you really need a full 40A, I'd recommend using the NI 9472 "digital output" cRIO module to drive the coil in your relay. It can easily handle the 100ish milliamps of the relay drive coil. Russ |
