Making a Sensor Board

[Astronouth7303]

I'm a programmer, so pardon me.

We used pots for finding the position of various parts. They're also used in joysticks and the like.

Encoders are used to find if something has passed it. Most of us use the banners. What we did was put reflectors on a black axle adaptor and used 2 banners to see if it was high or low. see the white paper on quadrature encoders.

Gyros can measure meassure angle of your robot (or something on it) if you use code. You need an accumulator to add the value at a regular interval.

There are the touch sensors, but I hope those are obvious. (Digital)

There are actually 2 pressure sensors. The one you MUST use is digital. The one you can use is analog. The former is turn compressor on/off. the latter is actual pressure.

the voltage sensor is important if a motor has a high stall and/or if it can break your robot. Analog. if it crosses a certain threshold (High or low), kill the motor.

The banners are also used for line following (on or off line).

Anything else I missed?

Just the newer one, Infrared. The IR sensors search for an Infrared beacon and travel towards it. I don't know how these work, however, because my team did not use them this year.
