Rotational Motion 100%

Key Ideas KEY IDEA ✪ Rotational kinematics uses essentially the same equations as kinematics, but distances, speeds, and accelerations are rotational quantities expressed with radians instead of with meters.

SwerveInverseKinematicsDerivation Swerve Inverse Kinematics    Inverse Kinematics  The goal of inverse kinematics is to determine the appropriate inputs to a system (in our case,  commands to the turning and driving motors) in order to produce a desired output (a velocity  vector and a rotational speed and direction for the robot). For swerve, we don’t need to  determine what to send the motors directly, since we’re using control loops for that, but we do  need to tell those control loops what direction and speed we want for the wheels.    Determining the outputs  The outputs we want are determined by user input. I decided to keep it simple and set the x  component of the desired velocity vector based on the x­input of the left joystick, the y  component of the velocity vector based on the y­input of the left joystick, and the desired  rotation based on the x­input of the right joystick. I’m considering joystick inputs to be on a  range from ­1 to 1.    Some definitions:  V​  ­­ The maximum speed one of our wheel pods can move  max​ V​  ­­ The desired velocity vector of the frame (componentized into V​  and V​ )  f​ f, x​ f, y​ ⍵​  ­­ The desired rotation of the frame; I’m defining counterclockwise as positive  f​ L ­­ The vertical length of the robot (measured between contact points of wheels)  W ­­ The width of the robot (measured between contact points of wheels)  √ 2 R =​   L
