Death of legged robots & rise of electric skateboards


Minitaur Explores the Outdoors (2 min 58 sec)


Ghost Robotics had another video, shortly after the last blog post. It's pretty slow on uneven terrain. Legged robots are once again busted.

Meanwhile, the lunchbox had a pretty successful 19 mile drive. It used 3455mAh from battery 1 on the bottom. 4374 from battery 2 on the top. It carried 12oz of fluid for 12 miles & the speaker for 19 miles. With the speaker & a drink, it was the mobile party originally envisioned. It reignited the idea for a new wheeled vehicle with a low center of gravity & much higher payload.

Electric skateboards now abound, but still can't steer remotely & they still cost over $600. They still work, despite rigid axles & no shock absorbers. With the Inboard M1, they started putting the motors inside the rear wheels instead of coupling by exterior belts. The hub motors still provide enough thrust to move a human around & take the minimum space. They might use a planetary gear but the millenial reviewers are completely unconscious about how anything works.

The skateboard is the model for the smallest possible drive train. Steering still requires a big servo outside the wheels. With no shock absorbers or tilt steering, the payload could be right down against the wheels.
