Webal. In quadruped robots, a good kinematic model is necessary to stability analysis and trajectory planning of system. There are two types of kinematic analysis: forward and inverse kinematics analysis. In the forward kinematic analysis, the joint variables are given to find the location of the body of the robot. WebThe BIG 4. The kinematic equations are a set of four equations that can be utilized to predict unknown information about an object's motion if other information is known. The equations can be utilized for any motion that can be described as being either a constant velocity motion (an acceleration of 0 m/s/s) or a constant acceleration motion.
