Disclosed is a traction robot, a conveyance system and a method for controlling a traction robot. The traction robot includes a main body, and further includes a control assembly and a rotating arm. The rotating arm is rotationally assembled on the main body. The rotating arm comprises a first rotating arm and a second rotating arm. The first rotating arm and the second rotating arm are both provided with a clamping part for clamping a towed article on one side facing the towed article, and expansion members are both provided between the clamping part and the rotating arm. The control assembly drives fluid input into or discharge from the expansion member to control expansion or retraction of the expansion member, so as to control the clamping part to clamp or release the towed article.

A tractor, including a frame, a power wheel and a connecting assembly. The power wheel is rotatably arranged on a bottom of the frame. The connecting assembly is arranged on the frame and is configured to be attached to a goods carrier. The power wheel is rotatable relative to the frame to drive the frame to move, so as to drive the goods carrier to move synchronously through the connecting assembly. The connecting assembly is configured to move back and forth along a first direction relative to the frame to render a relative position between the goods carrier and the frame adjustable along the first direction. The first direction is a travelling direction of the tractor.

A U-shaped drive frame has abase beam and parallel side beams defining an open implement area. Drive wheels support the side beams, and each drive wheel rotates about a horizontal drive wheel axis perpendicular to the operating travel direction. A steering control steers the drive frame in the operating travel direction. Implements are configured to perform implement operations and to rest on the ground surface when in an idle position. The drive frame moves rearward to a loading position where each implement is movable to an operating position supported by the drive frame. Each implement provides a beam lock connection between the side beams that resists twisting movement of the side beams to maintain the drive wheels and the side beams in a substantially fixed relationship with respect to each other.

A tractor for agricultural use includes a chassis, which connects a front tractor part and a rear tractor part to one another via a connecting element, a driver's seat in the region of the rear tractor part, a drive and at least four wheels. The connecting element of the chassis, which connects the rear and the front tractor parts to one another, is disposed at least 60 cm above the driver's seat and extends substantially horizontally up to the front tractor part. The driver can thus look to the right, and also at an implement disposed behind the front tractor part, below the connecting element. This enables precise maneuvering when tilling the soil for rows of plants.
