This was our first real build of something powered by little bits.
Materials Used:
The build took roughly 45 minutes. Building the structure was relatively simple. The motorized part was tricky and took a lot of trial and error. Key Lessons Learned from this build: 1) We should have made sure the post (the big cardboard tube) was more stable before adding the motorization. It kept tilting and we had to keep adjusting it. 2) We learned how to have the motor separate from the turning gear by using rubber bands and wheels instead of having the motor inline with the gear. 3) Having a large bag of various sized rubber bands was critical, as we needed to find the right thickness and tension between the wheels. 4) We used rubber bands to keep the motor attached to the lego bit. Then we had to use larger lego bricks for more connection points to stop the motor from popping off.
