sensors

I need more sensors. The only one I see of interest on the vexlabs site is the Vex Optical Shaft Encoder. (which I don’t know the range on that) I’ve got tons of ideas, but without the right sensors the autonomous ideas are shot. I haven’t recieved my starter kit yet, so I’m not sure what/if other sensors are compatible. If anyone could give me some ideas that would be great.

If you are entering an FVC competition, you are limited to using VexLabs’ sensors.

If the autonomous operation you are talking about is something you are doing just for fun, then you need to study the specs on the Vex microcontroller and learn enough to select compatible sensors on your own. Just asking “What sensors are compatible?” is akin to asking “How high is up?” It’s just not a well-formed question. In that case, try again and be more specific.

i agree with him but hope u bought a programming kit or ur gonna be limited to the bumper and limit switches that come with the starter kit

i have found that the ultrasonic sensor is very valuable to have.

What’s the difference between the optical shaft encoder and the ultrasonic range finder? I was thinking about setting up a grid of range finders and programming them so that the robot could track a moving target. It will require accuracy though.

an optical shaft encoder has an axle running through it and it basically measures how far the axle has traveled(like RPMs). you can use this to program the robot to go a certain distance. the range finder judges distance from an object like a wall but im not sure how accurate it is

Ultral Sonic, it depends on how it is used and what kind of surface and what angle the surface is…
