- Get everyone using the blog
- Fix practice feild
- Set up RobotC for Vex
- Test the robot
- Come up with manipulator designs
Last week during team 267's meeting, the partial circle goal got broken.
Here is Kevin creating metal brackets to repair it.
And here is one of the new brackets installed on the field.We started to get RobotC for VEX set up so that we can use the Vex bots from last year. We will be participating in a robot demonstration at OMSI this Saturday and plan to bring our Vex bots from last year as well as our new Tetrix bots.
Blackboard brainstorming...
Trying out the dump bed mockup that Ian made at home last night.
We have been having problems with the DC drive motors on our robot. We havent had fine motor control, which we really want. Coach Jeff reverted to an older version of RobotC and the problem went away, but that also removed the updates that came in the current one. When we shifted back to the current build, we again lost fine motor control.
Attitude is everything.

Today I helped the rest of the team gain access to this blog. I also took a look at some design ideas and into the problem we are having with our motors. Last night I spent some time making a full scale paper model of a possible design for a dump-truck-ish bucket/manipulator.
It turns out that the PID control option in the Motors/Sensors setup window measures the speed of the motor based on an encoder but we don't use the encoders on our drive wheels. Without encoders, it tells the robot that the motors arent moving and to apply more power. This explains why the motors only ever went one speed.
