1. A robotic system, the system comprising:
a robotic arm comprising an end-effector;
a robotic controller configured to control movements of the robotic arm; and
a dual-resolution computer-vision system;
wherein the dual-resolution computer-vision system comprises a low-resolution three-dimensional (3D) camera module and a high-resolution 3D camera module; and
wherein the low-resolution 3D camera module and the high-resolution 3D camera module are arranged in such a way that a viewing region of the high-resolution 3D camera module is located inside a viewing region of the low-resolution 3D camera module, thereby allowing the dual-resolution computer-vision system to provide 3D visual information associated with the end-effector in two different resolutions when at least a portion of the end-effector enters the viewing region of the high-resolution camera module.
