For the steering mechanism, we have revise the previous design and simplify their design by implementing a pulley and belt system to synchronize both the upper and lower steering arm. We then put on some dimension on the drawing and and we made a 1:1 scale drawing for our 1/4 scale model. We decided that lower steering mechanism can have some rooms of margin on the location since we need to provide some room for the fail-safe team's guiding wheels design. The upper steering arm is subject to minor changes since we want to further simplify our design by using one steering control arm with 2 green guiding wheels mounted on it.
