Couldn't you just use the absolute encoder to get around this?

Re: Motor Encoder code. LabVIEW

...It's included in the KOP, what other expenses are there?

Re: Motor Encoder code. LabVIEW

We're using 3 potentiometers on our robot this year and they work great. We'll also have encoders, but so far they don't work as easily. Plus, it's really easy to convert a potentiometer's voltage to an angle or distance (even changing where your base position is).

Re: Motor Encoder code. LabVIEW

Soo It sounds like Pots are alot more common and easier to use, and the only encoders we found in the KOP are a optical disk type of encoder that are relative encoders. There are small boards for rotary and linear encoders but the encoders themselves aren't included. We plan on going to radioshack and getting some pots to use.

"The encoders themselves" are embedded in the larger black integrated circuit devices on those boards. The two magnetic rotary encoders came with the small round magnets that are used with them. The magnetic linear encoder came with the thin flexible magnetic strip that is used with it.

Look at the Kit of Parts web page to find the Parts Data Sheets for the AS5030 - Rotary Magnetic Encoder and AS5304 - Linear Magnetic Encoder devices.

Re: Motor Encoder code. LabVIEW

Hey guys I had a quick question, where do we hook up the Potentiometers? I'm begining to branch out and learn some electronics to help some freshmen but the example vi on lv didn't help much.

Re: Motor Encoder code. LabVIEW

They are analog inputs, so use the Analog Breakout.
