This week at robotics we focused on the coding element. We made the robot move forward for 3 seconds and then back for practice, then started doing more complicated things.
We used trial and error to get to a green line and back, and we had to try a lot of times before we got it to work.
The final result is here, where we used rotations.
Then we moved on to the colour sensor, where we had to go to the green part of the line-following route and stop when we got to it. The colour green was the wrong shade, so the robot just went past it. Next week we will adjust the setting so that the different setting of green will work.
We also discussed that the method that was used to find the number of rotations to the green line was not foolproof, and if the wheels were bigger or smaller the distance travelled would be more or less.
WORD OF THE DAY: SPORADIC. This word means that something is temperamental, or something only sometimes works.
