The frame assembly 1 is assembled into a stable support structure by using special angle pieces and bolts from aluminum profiles 4040. The angle pieces are designed with raised parts that match the notches of the aluminum profiles. The notches of the aluminum profiles are fastened by bolts to form a stable connection point. The automatic detection process is started by the control system. The second motor 33 on the mounting plate 32 in the transmission assembly 3 drives the active sprocket 35 to rotate. The active sprocket 35 drives the driven sprocket 37 to rotate through the chain 36.
