This example shows a four-bar linkage modeled in Simscape Multibody that is optimized using MATLAB so that the tip of the linkage follows a desired trajectory.
Mechanical designers often wish to design mechanisms that will enable an end effector to follow a certain path. The lengths of the links and the position of the end effector influence the trajectory of the end effector in a complex kinematic relationship. Optimization algorithms can be used to tune those lengths to achieve the desired motion.
The process is similar to what is described in the video “Computational Design of Mechanical Characters” https://www.youtube.com/watch?v=DfznnKUwywQ
In this example, a parameter sweep is performed to see which trajectories are possible when varying a subset of the lengths. Then those lengths are tuned using MATLAB optimization algorithms until the resulting trajectory is within tolerances of the desired trajectory.
