Which sensors should be used throughout the robot?

These are from China and take absolutly forever to ship, but if you stock up on them now they're great to have, especially given the price.

We used them everywhere this year, two to sense totes, two to sense the tape on the floor for our 3 tote, and one to sense a container. Last year we used it to sense the limit on our catapult. Just don't be foolish like us and point two towards each other to try and sense the totes, you'll end up bending a sensor mount up so they don't interfere.

I also love these made for FRC sensors, thanks 971! We used them as the upper and lower limits for our elevator. Put velcro on the sensor and a 1/8 rivet on the magnet and you have an easily adjustable, great sensor.

Between these two sensors we've totally eliminated our use of pesky limit switches. I love their price and their ease of use.

Our school is unlikely to allow us to buy stuff through ebay. Any similar sensors from a more official website? Thanks!

Have you tried them for a flywheel?

A cheaper more durable alternative to the 971 WCP sensor are these inductive proximity sensors.

Since they are inductive instead of magnetic they can be triggered by anything ferrous like a steel rivet.

There are also magnetic hall effect versions http://www.ebay.ca/itm/Hall-Effect-H...em487c2a 613c

After accidentally posting in battlebots thread...

We used these Chinese encoders in place of S4's for practice bots to save some money.

They're way bigger, but worked well for us. Took about two weeks to get to us.
