Abstract

The paper deals with kineto-static analysis of the AGgressive Environment roBOT (AGEBOT). Serio-parallel kinematic architecture of AGEBOT plays important role in aggressive environment applications such as manipulation in industrial degreasing and paint removing lines in the presence of high pressure and temperature, acid or lye. Standard 4DoF serial manipulator with PRRR joints is equipped with special 3DoF parallel spherical wrist which makes possible to separate vulnerable components (motors, sensors) from the rest of the end-effector by a water-proof barrier. Inverse and direct kinematics are discussed. The algorithm for velocity, acceleration and static forces (gravity compensation) is derived. In the case of known inverse and direct position dependencies proposed algorithm can be generalized for an arbitrary serial or parallel manipulator.

化学侵蚀环境下机器人机械手的创新设计和控制
本文对攻击性环境机器人(AGEBOT)进行了动静力分析。AGEBOT的串行并联运动学架构在恶劣的环境应用中发挥重要作用,例如在高压和温度,酸或碱液存在的工业脱脂和油漆去除线中的操作。带PRRR关节的标准4DoF串联机械手配备了特殊的3DoF并联球形腕,可以通过防水屏障将易损坏的部件(电机、传感器)与末端执行器的其余部分分开。讨论了逆运动学和正运动学。推导了速度、加速度和静力(重力补偿)的算法。在已知逆位置依赖和正位置依赖的情况下,该算法可以推广到任意串联或并联机械臂。
