The Bipedal Walking Robot is a new addition to the Educational Construction Series. A walking robot moves by transferring its weight. When the weight transfer unit, which is composed of a gearbox and battery case, moves right and left, the model rocks and its legs move forward.
- Length: 85mm, width: 132mm, height: 107mm (138mm with guide rod attached)
- Weight: approximately 138g (including batteries).
- Two separately sold AAA batteries are required. Continuous running time: about 2 hours.
- Gear ratio: 114.7:1. includes a low-rpm type 130 motor.
- Speed: about 4.8cm/s (170m/h) (The model moves 1m in about 20 seconds.)
- Running on even surfaces is recommended.
- Features light gray plastic parts.
- The legs and plastic slides have holes to attach parts such as universal shafts, arms, and your original parts by tapping screws. Enjoy changing its appearance!
- Easy snap-fit/screw-together assembly
- Challenge level: 3 (5 is the highest). Approximate assembly time: 120–180 minutes.
Robot Movement
- Crank rotation is converted into reciprocating motion by the slider.
- Turning
- Adjusting the gearbox attachment angle and limiter alters the model direction.
- Gearbox attachment angle is adjustable in three directions (right, middle, and 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 decreases, and stride length becomes shorter.
- Attaching a 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.
