下面的MATLAB代码是计算出最终的各个关节的角度(configSoln),由于是用了迭代的数值解法,weights为权重,initialguess为给出一个初始估计。 ik = robotics.InverseKinematics('RigidBodyTree',puma1); weights = [0.25 0.25 0.25 1 1 1]; initialguess = puma1.homeConfiguration; [configSoln,solnInfo] = ik('L6...
MATLAB 用的是数值解法,可以理解为迭代寻优,或者近似解。 MATLAB 里面的反向运动学求解器(solver)有两个: Inverse Kinematics Generalized Inverse Kinematics 两者的区别是,后者比前者多了很多限制(constraints) 。例如end-effector的方向限制、机械臂各个关节的角度限制、位置限制等等。 我们先看一下比较简单的 Inverse ...

like an aiming constraint for a camera arm to point at a target location, can be set to IK solvers. Determining which IK solver to apply mainly depends on the robot applications, such as real-time interactive applications, and on several performance criteria, such as the smoothness of the fi...
Solve the Inverse Kinematics for Each Waypoint The inverse kinematics solver finds a joint configuration that achieves the specified end-effector pose. Specify an initial guess for the configuration and the desired weights on the tolerances for the six components of pose. The inverse...
