NettetYou create a CAD assembly by applying joints and constraints between parts. Each joint or constraint defines a kinematic relationship between constraint entities on the parts it connects. Angle and Insert are examples of constraints. Planes, lines, and points are examples of constraint entities. Consider the connection between the upper-arm and ... NettetUse the externalForce function to generate force matrices to apply to a rigid body tree model. The force matrix is an m-by-6 vector that has a row for each joint on the robot to apply a six-element wrench.Use the externalForce function and specify the end effector to properly assign the wrench to the correct row of the matrix. You can add multiple force …
