ClimbLab: MATLAB Simulation Platform for Legged Climbing Robotics
🤖 AI Summary
This study addresses the absence of dedicated open-source simulation platforms for legged climbing robots by developing a MATLAB-based simulation framework that supports arbitrary environments and multi-parameter adjustment. Methodologically, multi-body floating-base modeling is implemented using a rigid-body dynamics engine, introducing a novel climbing simulation architecture that integrates point cloud terrain mapping with dynamic gravity and stiffness modulation. Experimental results successfully validate the locomotion performance of a quadruped robot in wall-grasping and steep-slope climbing scenarios. By providing an efficient and reliable open-source analytical tool, this work significantly facilitates future research on complex-terrain climbing for legged robotic systems.
📝 Abstract
This paper presents an open-sourced MATLAB simulation and analysis platform dedicated to legged climbing robots. This simulator enables the design of any limbed robotic system as an articulated multi-body with a floating base and simulates it walking and climbing in an arbitrary environment. The main variable environmental parameters are inclination, gravity, and ground stiffness, and any point cloud can be installed as the terrain map. Furthermore, the simulator employs a rigid body dynamics engine. This paper first describes the simulator structure, and the computational flow and next presents the representative simulation examples where quadrupedal robots assumed gripping on the wall or climbing on the steep slope.
