Are Rigid Transmissions Limiting Robotics? The Case for Bio-inspired Elasticity
MarwaEldiwiny · x · 2026-08-06
The post highlights a fundamental limitation in current robotics design. The author points out that biological muscles can only pull, relying on antagonistic actuation, elasticity, and passive mechanics. While electric motors can generate torque in both directions, the rigid transmissions commonly used in robotics remove the natural suspension found in biology. The author questions why rigidity remains the default in the field.
