Chapter 6 Summary

The whole idea of Chapter 6 is about Supports. Mainly every robot built or car built is in need of supports. Having Gears is one of the most important parts of supports, a gear that is placed next to a supporting beam holds the beam well and decreases the slipping of the attached parts to the gear. The best way to resist both Tension and Compression is by adding extra connectors, by adding the connectors, the Tension and the Compression would have been lessened dramatically and with the Rigid assemably, it would not easily fall apart. The way that the new idea of studless beam works is that the studless beams can add both beams with stud and without. The old one only allows stud beams to connect. A creative reason for the studless beams was to let it cover up all the parts that show out. In any case, the most important part is the NXT itself, it is needed to be placed at the center just as a shape of a triangle. The reason for placing it at the middle is because it needs to keep the front and back both balanced, if either side is imbalanced, the robot would fall back or drop forth if it moves. Mainly, all problems lead to weight balance, the NXT itself has quite a big weight, as much as 2-3 Motors, if those both were placed in the middle, both front and back would be fine, but if they were all placed at back, they would tilt. The best ideal way would to be placing the NXT at the back/front, and the Motors at the opposite like a scale balance.
