Function: MakeCorkeRobot

MakeCorkeRobot(robotDic)

  • function description: makeCorkeRobot, creates robot using the peter corke toolbox using standard (stdDH) or modified (modKKDH) Denavid Hartenberg parameters

  • input:

    • robotDic: robot dictionary by exudyn robotic models

    • dhpara: stDH for standard DH parameter, modKKDH for modified DH parameter

  • output: serial robot object by corke

  • author: Martin Sereinig

  • notes: DH Parameter Information: stdH = [theta, d, a, alpha] with Rz(theta) * Tz(d) * Tx(a) * Rx(alpha) modDH = [alpha, dx, theta, rz] with used by Corke and Lynch: Rx(alpha) * Tx(a) * Rz(theta) * Tz(d) used by Khali: Rx(alpha) * Tx(d) * Rz(theta) * Tz(r) Important note: d(khali)=a(corke) and r(khali)=d(corke)

Function: ComputeIK3R

ComputeIK3R(robotDic, HT)

  • function description: calculates the analytical inverse kinematics for 3R elbow type serial robot manipulator

  • input:

    • robotDic: robot dictionary

    • HT: desired position and orientation for the end effector as 4x4 homogeneous transformation matrix as list of lists or np.array

  • output: solutions, list of lists with posible joint angles [q1,q2,q3] (in radiant) to achive the desired position (4 posible solutions,schoulder left/right, ellbow up/down ) in following order: left/down, left/up, right/up, right/down

  • author: Martin Sereinig

  • notes: only applicable for standard Denavit-Hartenberg parameters

  • status: testet with various configurations and joint angels

  • status: tested (compared with robotDiccs, Vision and Control book of P. Corke

Function: ComputeIKUR

ComputeIKUR(robotDic, HTdes)

  • function description: calculates the analytical inverse kinematics for UR type serial 6R robot manipulator without sperical wrist

  • input:

    • robotDic: robot dictionary

    • HT: desired position and orientation for the end effector as 4x4 homogeneous transformation matrix as list of lists or np.array

  • output: solutions, list of lists with posible joint angles [q1,q2,q3,q4,q5,q6] (in radiant) to achive the desired position and orientation (8 posible solutions,schoulder left/right, ellbow up/down, wrist flipped/notflipped (rotated by pi) ) [left/down/notflipped, left/down/flipped, left/up/notflipped, left/up/flipped, right/up/notflipped, right/up/flipped, right/down/notflipped, right/down/flipped]

  • author: Martin Sereinig

  • notes: Usage for different manipulators without sperical wrist posible UR3,UR5,UR10, only applicable for standard Denavit-Hartenberg parameters

  • status: under development, works for most configurations, singularities not checked -> ZeroConfiguration not working
