We're looking into using it as a learning experience and something big we (myself and a few others) can do in my (and some of theirs') senior year to learn and leave for the team to use. We have to first get the system up and running, probably building on what the AdamBots did and using a gumstix. Eventually, our goal is for the coprocessor to read and handle sensor inputs, as well as receieve the user inputs from the OI (via the RC), and do all computation and logic. We might end up leaving some sensors connected to the RC if it ends up being easier. We think it will be a great learning experience, but for game use, it will let us run as many sensors as we want, do high-level logic with them, and as much floating point and trig as we need to without worrying about the RC. If you have any comments, ideas, or suggestions, we'll be more than happy to hear them, as the project is still in its very early stages right now.

In 2003, first time they had autonomous mode, the then processor was very slow and bad. To do the autonomous mode we had to make a co-processor to process the quad encoders we used for the auto mode.

But the 2007 processor seems fine but I have always wanted to make a data logger.

As I said, we're interested in this partially for the challenge and learning, as well as for the advantages it will give us.

After we get all the basics up and running, I had a few more advanced ideas in mind. One of them would be a StangPS resembling system, that would record the position (in x and y) and the angle of the robot, using a gyro and an encoder. Are you thinking of data logging for the in-game purposes, or something to be analyzed between matches? What data would you record and why?

Collect data during the game and if something goes wrong have data to check to figure out what went wrong. This is especially helpful in the auto mode period.

What would collect is the sensor data, but maybe readings on key parts of the robot.

I used to do very difficult autonomous games that the robot would do all the game in auto mode. Data collection was very important in figuring out what the robot was trying to do and what the sensors were reading.
