Reflections For This Meeting: 

The robot is looking good for state tomorrow.

We need to practice driving more.

 Today I came over by myself to work on programming the robot for state competition. I had to finish programing the doubler baton grab, for autonomus mode and the score and balance during autonomous - and a defensive program that would sit us in front of the doubler baton dispenser.

I also worked on finishing the tele-operated program for the drive team which looks like it will be Chris driving and Karl doing arms. The next step will be for them to get some good driving practice in.

Reflections For This Meeting: 

Sometimes it is best for programmers to have their own time

Today, I came over for pretty much the entire day to work on programming the robot.

I concentrated on creating several autonmous programs. I got the following:

1. Got 5 starting batons scoring

2. Got the balance on the bridge to work! Woo Hoo!

- To do the balancing, we use both the accelerometer and the gyrosensor at the same time. The gyro is mounted sideways- which then tells us when the bridge is moving. So, when it is moving - we stop - and when it is moving we try and balance. Read more »

 Wiring takes a long time, but Al does a really great job!

 

This was our first big meeting of winter break. We have a bunch of stuff that we have to get done and we made a list of things to accomplish on the white board (see last photo for 'before' and 'after')

We probably won't get to the plastic today, but hope to have the robot moving by the end of the meeting. Everyone will be here today, and Al and I will be spending the night - so we should be able to accomplish a lot today.  Read more »

Reflections For This Meeting: 

Soldering takes forever, and we've decided that Al is our new wiring guy. But, thats o.k, because he is really good at it.

 Our biggest goal this meeting is to get all the prototype board sensors mounted and wired to the prototype board. This includes soldering and connecting. AL is also going to focus on making the wiring harness for the servors on the hand, and feeding those all the way back to the servo controller. It would be really cool if we could get the robot 'legs' on by the end of the meeting too - as Alice looks a bit odd without her legs attached. Read more »

Reflections For This Meeting: 

Learning about PID's are fun... if you like math

In order to make the arms move to the right spots and stay there, we had to come up with a way to control them. Since the motors want to drift after telling them to stop (even if the right command is given in software), we figured that we'd have to come up with a method of controlling them based on the position (from the prototype board).
