Which type of motion is typically used for reaching a specific coordinate in robotics?

In robotics, reaching a specific coordinate is commonly executed using Point-to-Point (PTP) motions. PTP motions involve moving a robotic arm or end effector directly from one predefined point to another in the Cartesian space without regard for the path taken in between. This type of movement is particularly efficient for tasks where the exact trajectory is not critical, allowing for rapid repositioning between distinct coordinates.

PTP motion is advantageous because it simplifies the programming and execution process, especially when the goal is to reach a specific point quickly. The robot's control system interprets the commands to adjust its joints or axes accordingly, leading to efficient path planning. This is useful in various applications, such as assembly, pick-and-place operations, and when operating in environments where time is crucial.

The other types of motion mentioned may serve different purposes but are not oriented specifically towards reaching singular coordinates with the directness offered by PTP motions. For instance, Continuous Path (CP) motions focus on smooth path trajectories while the robot is in motion, which is essential for tasks requiring fluidity. As one might infer, LIP and RTM motions serve specific roles in different contexts of robotic movement. Thus, PTP motions stand out for their effectiveness in achieving precise positional goals.
