[0025] It should be noted that, in this embodiment, the small six-degree-of-freedom sorting robot 2 is small in size and light in weight, and the sorting and handling operation of small goods is more flexible and the processing method is faster. The robot can work efficiently at the return end of the conveying equipment 1, reducing the floor space and improving the handling efficiency of small goods on the logistics transmission line.
[0026] Furthermore, the arm 21 of the small six-degree-of-freedom sorting robot 2 has an arm length of 250MM and a short stroke, which reduces the time of a single operation cycle and improves work efficiency.
