MORPH Wheel: A Passive Variable-Radius Wheel Embedding Mechanical Behavior Logic for Input-Responsive Transformation
A smart wheel that physically adapts to terrain, making robots more capable without complex controls.
Deep Dive
Researchers have developed a purely mechanical wheel that changes its radius from 80mm to 45mm in response to the torque it experiences. It uses springs and a special coupler, requiring no sensors, actuators, or electricity. The design allows for high-torque operation and precise control, enabling robots to automatically adjust for different loads and slopes. This 'mechanical intelligence' could make robots simpler and more reliable in unpredictable environments.
Why It Matters
This simplifies robot design for rugged, real-world use where electronics might fail.
