4 Degrees of Freedom Robot Arm With a Twist STM32F4 - Processor in the Loop Inverse Kinematics of a Two-Link Planar Elbow Manipulator (Symbolic Math) Solving the 4 Degree of Freedom (Matlab Script) Simulink Matlab Function Block Implementation Simulation with Simscape Multibody Processor in the loop with STM32F4 Discovery Board What we need Results Next Steps This is a documentation of steps being done to be able to solve the 6 Degree of Freedom Robot Arm bought online.  This goes through the process of solving the inverse kinematics of a Two-Link Planar Elbow Manipulator which is the basis of our case. Wrist and Clamps was not solve here &_& Inverse Kinematics of a Two-Link Planar Elbow Manipulator x d , y d  = location of the tip of the manipulator     q 1d ,  q 2d  = angles of the links (counter-clockwise is positive)  q 3d  = dummy angle q 4d  = dummy angle L1, L2 =  lengths of the links (constant) th1d := Symbol::subScript(Symbo
