Technical Problem

[0005]本申请主要解决的技术问题是提供机器人站立姿态的恢复方法、装置、设备、存储介质及产品,解决了机器人倒地时的预设的刚性动作往往与当前实际支撑状态不匹配,导致机器人在执行起身动作时,容易出现重心失衡的技术问题

Benefits of technology

[0016]上述方案,在检测到机器人处于倒地状态时,对所述机器人的多个关节角度进行实时采集,得到倒地姿态数据,并基于所述倒地姿态数据对所述机器人与地面的多个接触点进行解算,得到支撑部位集合;获取预设的零力矩点参考轨迹,所述所述零力矩点参考轨迹是基于机器人动力学模型预先设定的理想零力矩点变化路径,用于指导所述机器人从倒地状态稳定恢复至站立姿态;基于所述支撑部位集合对零力矩点参考轨迹进行逆动力学解算,得到关节运动序列,并根据所述关节运动序列对所述机器人的各关节进行位置指令配置,得到起身规划轨迹;基于所述起身规划轨迹对所述机器人的各关节的当前输出力矩进行实时补偿,得到驱动力矩指令,并通过所述驱动力矩指令对所述机器人的各关节电机进行驱动控制,使所述机器人从当前姿态恢复至站立姿态,解决了机器人倒地时的预设的刚性动作往往与当前实际支撑状态不匹配,导致机器人在执行起身动作时,容易出现重心失衡的技术问题。本方案通过实时感知倒地姿态并解算支撑部位集合,实现了对当前实际接触状态的精准识别;以此为基础动态生成零力矩点约束下的关节运动序列,并结合力矩补偿机制进行驱动控制,使起身动作与真实支撑条件相匹配。该方法避免了依赖固定动作模式导致的重心偏移与失稳,提升了机器人在复杂跌倒姿态下自主恢复的适应性与可靠性,有效解决了因规划动作与实际支撑不协调而引发的二次失衡问题。

Abstract

The application relates to a robot standing posture recovery method, device, equipment, storage medium and product, which comprises the following steps: after detecting a robot falling state, acquiring falling posture data by collecting joint angles in real time, solving contact points with the ground to determine a support part set; combining a preset zero moment point reference track, performing inverse dynamics solving based on the set, generating a joint motion sequence, configuring each joint position instruction to form a standing-up planning track; according to the track, real-time compensation is performed on the current output torque of each joint to obtain a driving torque instruction, and each joint motor is driven to execute an action, so that the robot is recovered from the current posture to the standing posture, and the technical problem that the preset rigid action of the robot when falling often does not match the current actual support state, leading to the robot being prone to center of gravity imbalance when executing the standing-up action is solved.
