Small centimeter-scale robots can freely navigate through narrow gaps in industrial facilities, natural caves, disaster ruins, and other confined spaces, performing inspection and exploration tasks that are difficult for large robots to reach.
Additionally, due to their use of cheaper materials in smaller quantities, small centimeter-scale robots demonstrate economically efficient characteristics when deployed on a large scale.
With these unique advantages, small centimeter-scale robots are gradually emerging in the robotics field.
However, small robots are simultaneously facing challenges from hardware limitations. Due to size constraints, small robots typically lack sufficient sensing, actuation, and control resources, making it difficult to provide active dynamic stability during movement.
The limitations in actuator quantity, power density, and precision directly result in insufficient robot stability and maneuverability. Furthermore, on non-flat terrain, small robots struggle to move effectively and efficiently, which further limits their application scope.
Among design approaches for improving robot stability and maneuverability, multi-legged designs have played a role to some extent, but they also bring complexity and space occupation issues.
In contrast, while bipedal robots have more streamlined designs, they face greater challenges during miniaturization. How to achieve robot miniaturization, stability, and efficiency while maintaining bipedal walking characteristics has become an urgent problem to solve.
