How does torque influence robotic joints?

Torque is a crucial factor in the operation of robotic joints because it directly affects the ability of those joints to move. In robotics, torque is the rotational force applied to an object, which is especially relevant in mechanical systems where joints provide motion. The amount of torque that a joint can generate will determine its capacity to perform tasks, such as lifting loads, moving quickly, or reaching specific angles.

When a joint has sufficient torque, it can execute movements smoothly and efficiently, adhering to the desired trajectory and responding to control inputs. If the torque is too low, the joint may struggle to move or could fail to move at all under load. This concept is foundational in robotic design, particularly in selecting motors and actuators that will provide the necessary torque for the intended applications. Understanding torque's role helps engineers design better robots that can perform their tasks reliably.
