1. A method of controlling a robot, the method comprising:
- forming a first bell-shaped velocity profile in response to a start time and an end time of a motion of the robot;
calculating a value of an objective function having a limited condition according to the first bell-shaped velocity profile; and
driving a joint of the robot in response to a second bell-shaped velocity profile that minimizes the objective function having the limited condition.

Abstract
A robot and a method of controlling the same are disclosed. The robot derives a maximum dynamic performance capability using a specification of an actuator of the robot. The control method includes forming a first bell-shaped velocity profile in response to a start time and an end time of a motion of the robot, calculating a value of an objective function having a limited condition according to the bell-shaped velocity profile, and driving a joint in response to a second bell-shaped velocity profile that minimizes the objective function having the limited condition.
