Challenge : Drag race


The challenge is to build a robot to be the fastest in the 3m track. It didn't need sensors except the sound sensor for fair start, but it required some techniques of construction and knowledge of gears. 
We first came out with the idea of the gear train. For more efficiency, we used the gear train of four gears with the same gear ratio, 1:40. Even I tried to build the gear train of six gears on each side, but Loren asked me not to do so, which was lucky. In the first trial, it couldn't move anyhow, which was because it couldn't bare its own weight. We had to take out the second parts of the gear trains; the robot functioned well. To prevent it from flopping, a back wheel was added. Of course, it was programmed to have a maximum speed.

Luckily or as a result of our brilliant techniques, we won the second place.

Good overview of what we did...yeah pretty smart that we decided not to use the gear train...considering what we saw happen to some competitors with gear trains and no support...the robot just died...
