Abstract
A handling system and a control method thereof are provided. The system includes a mobile vehicle, a robotic arm, a lifting mechanism, a first sensor, a second sensor, and at least one controller. The controller controls a platform of the lifting mechanism to perform a first movement according to a target height detected by the first sensor. In response to the first movement, the controller controls the platform to perform a second movement according to a height difference between the platform and a target position, where the height difference is measured by the second sensor. Therefore, accuracy and stability of alignment of the handling system could be effectively improved.
Claims19
A handling system, comprising:
- a mobile vehicle;
- a robotic arm disposed on the mobile vehicle and configured to clamp an object;
- a lifting mechanism disposed on the mobile vehicle and having a platform for placing the object;
- a first sensor configured to detect a target height corresponding to a target position, wherein the target position corresponds to a position of the object;
- a second sensor configured to measure a height difference between the platform and the target position;
- at least one controller electrically connected to the mobile vehicle, the robotic arm, the first sensor, the second sensor, and the lifting mechanism, and configured to:
- control a first movement of the platform according to the target height;
- and
- in response to the first movement of the platform, control a second movement of the platform according to the height difference.
A control method, comprising:
- providing a handling system, wherein the handling system comprises a robotic arm, a lifting mechanism, a first sensor, a second sensor, and at least one controller, the robotic arm is configured to clamp an object, and the lifting mechanism has a platform for placing the object;
- detecting a target height corresponding to a target position by the first sensor, wherein the target position corresponds to a position of the object;
- controlling a first movement of the platform according to the target height by the at least one controller;
- measuring a height difference between the platform and the target position by the second sensor;
- and
- in response to the first movement of the platform, controlling a second movement of the platform according to the height difference by the at least one controller.
