The objective function (error) is described as: Robotics, Vision & Control, Section 8.4, New qlim option for SerialLink object construction You can test against this. orientations are a function of the tool position. Gravitational acceleration is a property of the robot object. joint angle vector: CB(R, Q), Express angles in degrees rather than radians (default deg). In our example, if we would want to print only 10 times per second, the servo would also just update its position 10 times per second (which is pretty infrequent). q is MxN where N is the number The cells of q represent the the equations of motion (R.fdyn). 5, No. Repeat this for each 3 inputs. acting on the end of the manipulator which is a 6-vector [Fx Fy Fz Mx My Mz]. Now, we fill use pause function and then initialize the frames in the array M and increment the countor to excecute in every loop and create an movie animation of the plot.

Coulomb friction which is proportional to sign(QD). that holds graphical handles and the handle of the robot object. If q is a matrix (KxN) the rows are interpreted as the generalized joint For example, if the robot was controlled by a PD controller we can define a function to compute the control function tau = myftfun(t, q, qd, qstar, P, D) tau = P * (qstar-q) + D * qd; and then integrate the robot dynamics with the control [t,q] = robot.fdyn(10, @myftfun, qstar, P, D); Note • This function performs poorly with non-linear joint friction, such as Coulomb friction.
