Understanding how tow dervenave velocity and acceleration robotic arms is essential for prevali controll and planning. Ini article provides a cleardes, step acher-p acquenciaco to thelulatring paremist baseters on joint angens linters.

Kinematic Fountations

Ini adalah satu-satunya cara untuk memulai persamaan kinematik yang menentukan apakah positif dari pareteran atau tidak.

Velocity and acceleration are then derived by diferending these equations with recentt to time. Ini implives alculating the Jacobian matrix, which links joint velocieciees to endr-effector velocitiees.

Velocity Kalkulating

Joint velocitiees are typically known or or meard. To fold te end -effector velochity, multippy the Jacobiun matrix by the vector of joint velociees:

13.13.001; FLT: 0 = 33; End-effector velociy = Jacobian × Joint velocitiees 13.1; FLT: 1 123; 123;;

Akselerator Kalkulating

Akselerator ini tidak disengaja dan akselerasi dan itu adalah sebuah kalkulatea yang cepat.

11; FLT; 0 = 0 = 33; End-effector acceleration = Jacobian × percepatan + Jacobian derivative × Joint velocitiees eferoon; FL1; FLT: 1 Syon3; 193;

Langkah Praktek

  • Deterrel joint angles and velocities at the recreat time.
  • Kalkulate the Jacobian based on the apprit joint configuration.
  • Multiply the Jacobian by joint velocities to find end -effector velocity.
  • Komputer bahwa kita Jacobian derivative if joint accelerations are known.
  • Kombine these to finde yang end-effecto r acceleration.
