kinematics
Meaning: The branch of mechanics concerned with the motion of objects without reference to the forces that cause the motion.
Kinematics describes how things move — their position, velocity, and acceleration — without asking why they move. This distinguishes it from dynamics, which considers forces and their effects. Kinematics is fundamental in physics, engineering, and robotics, where understanding motion patterns is essential for designing machines, vehicles, and control systems.
Examples
- The kinematics of the robotic arm were calculated to ensure precise movement along the assembly line. 为确保沿装配线的精确运动,计算了机器人手臂的运动学参数。Se calculó la cinemática del brazo robótico para garantizar un movimiento preciso a lo largo de la cadena de montaje.組立ライン上での正確な動きを確保するため、ロボットアームの運動学パラメータが計算された。조립 라인에서의 정밀한 움직임을 보장하기 위해 로봇 팔의 운동학적 매개변수가 계산되었다.
