Communication ECA Phase 1 Class 7: Fishing Rod 20191023
Square lake Lego fishing!!! Last class we built a working fishing rod with a lego fish to go with. The rod had a crank to control the ropes movement and had a safety mechanism using a gear and a lever to stop the fish swimming away if the crank was released. This insured maximum control on our fishing voyage! The fish was built out of long beams and odd shaped pieces. Although there was no moving parts with the fish the angles the class were using in the build made a complex and challenging build. Everyone did a great job completing their fishing rods and had a lot of fun trying to catch some fish!!! Next week everyone should be excited for the opportunity to have some choice in the build they do! Being our last class i look forward to seeing which build the class will choose and how they’ll customize they’re builds to make it their own!
Lego EV3 Self-Driving Challenge Final
Tonight is the Lego EV3 Self-Driving Challenge Final. All teams get into final testing stage. Able to complete all task maybe is 50% of the work. We can fine tune the robot forever. Think about the real cars. People invented automobile for over 100 years. Every year, we still find new way to improve it. I hope all student can keep your curiosity, find new way to improve your creativity. Keep building.
Lego EV3 Lane Following
Welcome to the last two classes. We are going to build a team project, build a robot that can follow the curved road to the end, finish some task, then follow the same road home. The robot is ranked by the scores it can earn for completing tasks. All team effort, quality of the code, comments are scored as well. This challenge will require some of the knowledge from previous class. Also, the fundamental lane following codes are provided as reference. Students can explore more options by try and error on the map. It is a challenge problem. Some teams finished some tasks in this class. We are looking forward to see them finish all tasks by next class. Thank you for cleaning up every class. We are going to celebrate learning next class.
Communication ECA Phase 1 Class 6: Charge up Dragster 20191016
Last week we build a charge up dragster. There were 2 parts to the build, the charging tower with the motor and the dragster car. The tower had a lever that lifted the car off the ground and connecting the car wheels to the motor through a series of gears. The wheels gain up speed so that when the car is brought back to the ground the car drives off. This was probably my favorite build so far to do with the class because of its complex gears and features.
