摘要:

本文提出了Kinova Gen 3 Lite机器人运动学逆问题的多项式解法。该串联机器人基于6 R运动链,并且没有腕部分区。我们首先从正运动学方程提供的位置和方向的末端执行器,最后,一元多项式方程作为第一关节变量$θ_{1}$的函数。剩余的关节变量通过回代计算。因此,对于单变量方程的每个根,获得关节位置的唯一集合。数值例子,在ROS(机器人操作系统)模拟,给出验证结果,这是比较与MoveIt!and with the actual实际robot机器人.还提出了一个程序来选择一个最佳的姿态的机器人。

英文摘要:

A polynomial solution to the inverse kinematic problem of the Kinova Gen3 Lite robot is proposed in this paper. This serial robot is based on a 6R kinematic chain and is not wrist-partitioned. We first start from the forward kinematics equation providing the position and orientation of the end-effector, finally, the univariate polynomial equation is given as a function of the first joint variable $θ_{1}$. The remaining joint variables are computed by back substitution. Thus, an unique set of joint position is obtain for each root of the univariate equation. Numerical examples, simulated in ROS (Robot Operating System), are given to validate the results, which are compared to the coordinates obtained with MoveIt! and with the actual robot. A procedure to choose an optimum posture of the robot is also proposed.
