What kinematic parameter primarily determines the reach of an articulated robot?

The primary kinematic parameter determining the reach of an articulated robot is the combined length of its arm links. An articulated robot typically consists of multiple links connected by joints that allow for rotational movement. The reach refers to the maximum distance the robot's tool center point (TCP), which is the point where the robot interacts with its environment, can extend from its base. Each link contributes to the overall reach, and the sum of the lengths of these links, when fully extended, dictates the robot's maximum working area. For instance, a robot with three links, each 0.5 meters long, would have a maximum reach of approximately 1.5 meters, assuming the links can extend in a straight line. Other factors like joint angles and the specific configuration of the robot arm also influence the actual reachable workspace, but the total length of the links is the fundamental determinant of its maximum possible reach. The longer the combined length of the links, the larger the workspace the robot can access. The kinematic parameters are those that define the geometry and movement capabilities of the robot arm.
