Robot payload information includes mass, center of gravity (COG), and what else?

Robot payload information is crucial for ensuring that the robotic system functions optimally and safely. In the context of payload characteristics, mass and center of gravity (COG) provide foundational data about the weight and distribution of the load the robot will carry. The third key component, inertia, is essential because it quantifies the resistance of the payload to changes in its motion.

Inertia plays a significant role in determining how the robot will behave while accelerating, decelerating, or stopping with a given load. It influences the robot's performance, affecting the rates of acceleration and deceleration that can be safely achieved without risking instability or damage to the robot and its payload. Therefore, understanding the inertia of the payload helps in designing control systems and selecting suitable speeds and paths for the robotic arm's movement.

The other options, while related to motion, do not directly fall under the standard definitions of payload characteristics in the same way that inertia does. Velocity and acceleration refer to the dynamics of the robot's movement rather than the properties of the payload itself. Torque, while essential for understanding the forces at play in robot joints and movement, does not provide a direct measure of the payload's properties like mass, COG, and inertia do. Hence, inertia completes the essential
