Communication ECA Phase 1 Class 4: Big Wheel Brick Sweeper 20191002

Week 4!!! Had a great time creating our Lego Sweepers. We used gear ratios again to speed up our Sweeper rotation speed! A big unique factor of this build was how the build connected the sweeper rotation to the wheel rotation. This engaged the sweeper when ever the vehicle was in motion! After the build we used lego blocks as trash and swept it out of the way using our new build! Everyone used their creative skills to upgrade the sweeper to have more arms and better efficiency! Can’t wait till next week, we’re building a flywheel roadster!!!

Lego EV3 Lane Following

Welcome back the lego EV3 self driving challenge. Today, we put what we have learned skills together to build a color sensor lane following car. It also called “Bangbang lane follower”. There are only hand full of coding block today. But today we need test our robot on map, see if it can follow the lane for more than two meters. We spend some time to make a notes in the program, so we can read at home, or we can understand other people’s code. Each student have three difficulty level programs to test on the track. We do need sometime to debug. We have good time on the track tonight. Next class we are going to build cruise control for the vehicle. Feel like we are run out of display room for your program. We have solution in next class. Thank you again for set up and clean the room.
