Task Space control of RPRP manipulator

Forward and inverse kinematics of RPRP manipulator with task space control to trace trajectories.

Forward kinematics:
It is applied through homogeneous transformation matrix, almost in the similar fashion as any CAD software perform rotation and translation of CAD model.
Inverse Kinematics:
It is applies through the use of MATLAB's fmincon and ode45 functions.
Task space control
Applies Jacobian matrix formulation and pseudoinvrse of it.
Task space control is carried out to trace two user defined standard trajectory, namely circle and ellipse. The control performance if better in the case of circle. Since, we are applying only proportional control we have slightly inferior performance in case of ellipse.
