Synchronized legged robot

Legged robot with synchronized parallelogram linkage for width and height adjustment

This technology is a synchronized legged robot that adjusts its width and height by transmitting the vertical movement of a single actuator to a moving plate, which is connected to multi-jointed legs configured with a parallelogram linkage structure.

Conventional mobile robots often use individual actuators for each wheel-leg, leading to complex control, high manufacturing difficulty, and reduced mobility in narrow spaces or poor storage efficiency due to a fixed width.

This technology features multiple legs pivotally coupled between a support plate and a vertically movable plate, allowing the legs to rotate in synchronization as the moving plate moves up or down. Applicable to indoor delivery robots and narrow-aisle inspection robots, it reduces both manufacturing costs and control complexity by enabling shape transformation with a single actuator.

Key Features:

• A support plate and a moving plate positioned at a predetermined distance above it
• An actuator that raises and lowers the moving plate to adjust its height relative to the support plate
• At least three leg units provided along the perimeter of the moving plate, each equipped with a wheel at the end
• A configuration where the leg units are coupled to rotate in synchronization relative to the movement of the moving plate
