AI总结:

针对现有轮腿机器人成本高、缺跌倒恢复的问题,研究提出低成本轮式四足机器人的恢复感知视觉惯性导航系统,结合深度视觉与深度强化学习实现稳健运动、跌倒恢复与目标导航,降低了预算受限平台的部署门槛。

摘要:

轮腿机器人结合了轮式的高效性与腿部的越障能力,但许多最先进的系统依赖昂贵的执行器和传感器,且跌倒恢复功能很少被集成,尤其是针对轮腿形态的系统。本研究在一款低成本轮式四足机器人上提出了一套具备恢复感知的视觉惯性导航系统。该系统利用深度相机的视觉感知与深度强化学习策略,实现多种地形下的稳健运动及跌倒后的自主恢复。仿真实验表明,该系统搭载低扭矩执行器时,能在不规则地形上实现灵活移动,并能可靠地从外部扰动和自身引发的故障中恢复。我们进一步展示了其在结构化室内空间中借助低成本感知实现目标导向导航的能力。总体而言,该方法降低了在预算受限的机器人平台上部署自主导航与稳健运动策略的门槛。

英文摘要:

Wheeled-legged robots combine the efficiency of wheels with the obstacle negotiation of legs, yet many state-of-the-art systems rely on costly actuators and sensors, and fall-recovery is seldom integrated, especially for wheeled-legged morphologies. This work presents a recovery-aware visual-inertial navigation system on a low-cost wheeled quadruped. The proposed system leverages vision-based perception from a depth camera and deep reinforcement learning policies for robust locomotion and autonomous recovery from falls across diverse terrains. Simulation experiments show agile mobility with low-torque actuators over irregular terrain and reliably recover from external perturbations and self-induced failures. We further show goal directed navigation in structured indoor spaces with low-cost perception. Overall, this approach lowers the barrier to deploying autonomous navigation and robust locomotion policies in budget-constrained robotic platforms.
