Inverse Dynamics
Mechatronics & Robotics · Biomedical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Inverse dynamics computes the joint torques required to produce a desired trajectory of a robot manipulator. It is essential for model-based control and feedforward compensation.
Example in context
“The controller uses inverse dynamics to calculate the necessary motor torques for the specified motion.”
“Kontrolör, belirtilen hareket için gerekli motor torklarını hesaplamak üzere ters dinamiği kullanır.”
Where engineers use it
Inverse dynamics is used in robot controllers to compute feedforward torque commands for accurate trajectory tracking. Engineers rely on it to cancel dynamic effects like inertia and Coriolis forces.
Antonyms: forward dynamics
In Biomedical Engineering
A computational method that derives internal forces and moments at joints from measured motion, segment inertial properties and external contact forces. It works backwards from kinematics to the loads that must have produced them.
“Using inverse dynamics, the team combined marker trajectories and plate forces to estimate knee joint moments throughout the stair descent cycle.”
Practice: can you use “Inverse Dynamics” at work?
A robot arm must follow a high-speed pick-and-place trajectory. The learner is asked to determine the required joint torques using inverse dynamics, considering the arm's inertia and Coriolis forces.
Show a model answer
“We need to apply inverse dynamics for precise torque feedforward in this robotic arm.”
