The KT-X humanoid robot is a major development in robotics, specifically designed to advance human-robot interactions and mimic human movement. Created by the Korea Institute of Industrial Technology (KITECH), the KT-X series began in the early 2000s with the goal of building a versatile robot that could help in areas like research and education. These robots are known for their flexibility provided by their many degrees of freedom (DOF) which allows them to perform a wide variety of tasks. The KT-X 13 DOF humanoid robot has 13 degrees of freedom, meaning it has 13 independent joints or axes of movement. This includes the head, arms, torso, and legs, allowing for complex movements. The number of DOF is important because it determines how lifelike and versatile the robot's movements are. The KT-X 13 DOF is designed for tasks requiring flexibility and precision, such as research and testing human-robot interaction.
