Obstacle-climbing robot

Obstacle-climbing robot with caterpillar relative rotation and variable-length linkage for stair traversal

This technology features an obstacle-climbing robot that connects a first driving unit with a pair of first caterpillars to a second driving unit with a second caterpillar using a variable-length linkage. Each driving unit is equipped with an independent rotation motor and gear system to adjust the driving angle.

Existing robots have fixed hardware structures and movement trajectories, which limits their ability to overcome obstacles or stairs above a certain height.

This technology uses a linkage to adjust the distance between the two driving units, while the first and second rotation motors independently drive their respective axes to adjust the caterpillar angles to match the shape of the obstacle. It can be applied to disaster site exploration, indoor delivery, and military reconnaissance robots, allowing them to perform missions without movement restrictions even in environments with a mix of stairs and uneven terrain.

Key Features:

• A first driving unit with a pair of first caterpillars capable of traveling along the ground
• A second driving unit positioned behind the first driving unit, featuring a pair of second caterpillars capable of traveling along the ground
• Linkage members positioned on both sides that connect the first and second rotation axes and allow for length adjustment
• A first driving unit configuration that includes a first rotation gear coupled to the first rotation axis to drive the relative rotation of the caterpillars
