정말 그냥 서보로 떼우는게 저렴해지면서 점차 뭔가 잃어가고 있는 것 같다는 기분이 듬..
조이드는 모터 단 하나로 이런 짓을 했었는데..
What If One Motor Could Move an Entire Robot Leg?
Quaddle takes a very different approach to quadruped mechanics.
Instead of using separate motors for the hip and knee, each leg uses a single servo with a mechanical linkage that drives both joints. That cuts the actuator count to just four servos for the whole robot.
The interesting part is that the mechanical design does more of the work normally handled by extra actuators. With the right linkage and gait timing, Quaddle can walk, move sideways and spin in place.
Less motors. Less wiring. Less weight.
More mechanical engineering.
Also, the hardware and motion system can be hacked and experimented with.
Would you try designing your own leg mechanism around this idea?
