Robot Movement
• Crank rotation is converted into reciprocating motion by the slider.
Turning
• Adjusting gearbox attachment angle and limiter alters the model direction.
• Gearbox attachment angle is adjustable to three directions (right, middle, left), and it can be changed even after assembly. (If gearbox is moved to left, the model turns right.)
• The legs have limiters to limit model lean. When the limiter is down, the body lean is decreased, and stride length becomes shorter.
• Attaching guide rod redirects the model if it hits an obstacle.
• Making the model hold things such as an AAA battery (approx. 11g) changes its center of gravity, which lets the model turn.
