Robot build report from Sean: The kids got some great insight on which missions really need sensors, versus the ones that only seem to need them until you read the mission really carefully!
George worked with a few kids from both teams on strategic analysis of the missions. Our goal is to take the progress they made and have each team pick a start point come Friday.
Programming report from Sarah: I enjoyed working with Anna, Jackson, Cashion and Ashton on EV3 programming. Software/hardware/incompatibility glitches meant we couldn’t download the programs onto the robot, so we did everything short of actually running the programs.
We walked through the green palate blocks, and looked at large motor, medium motor, move steering and move tank blocks in particular. We had the robot in front of us, looking at how one wheel was attached to the motor plugged into the A port, and the other wheel was attached to the motor plugged into the B port. What would happen if the A motor only were told to move forward – would the robot go forward? (No – it spins in a circle). We talked through turns and how the motors used and the direction of the motors can dictate the type of turn. We measured the circumference of the wheel and talked about how to calculate the distance traveled. The wheels on the robot we had in front of us were approximately 7 inches. If we want the robot to travel forward 3.5 inches, that’s ½ of a rotation. If we want it to travel 9 inches, that’s 1.286 rotations.
The kids each did a very short program, which I promised we’ll run on Friday.
