The present invention belongs to the field of robots, and relates to a soft ground crawling robot. Front wheels are connected on both sides of the front end of a body shell; a universal wheel is arranged on the rear end; rotary stepping motors are installed on both sides of a supporting assembly; an output shaft of the rotary stepping motor on each side passes through the body shell and then is connected with the front wheel on the same side; a swinging stepping motor is installed on the supporting assembly; the output shaft is connected with a connecting plate; the connecting plate is connected with the body shell through a connecting shaft; the body shell is driven to swing by the swinging stepping motor; lower end covers are rotatably connected on both sides of the body shell; a wheel bracket is connected to the rotary stepping motor on each side; and the wheel bracket on each side is connected with the lower end cover on the same side. The crawling robot of the present invention can crawl on all soft ground while moving in a plane, and overcome the phenomenon that some existing crawling robots cannot walk and work on the soft ground such as sand due to sinking.

A robotic obstacle-crossing device mainly includes a wheel body and an obstacle-crossing body, wherein the wheel body includes a wheel part, a first obstacle-crossing part and a second obstacle-crossing part. When the sweeping robot tilts, the plurality of first recessed portions and the plurality of second recessed portions provided on the periphery of the first obstacle-crossing part and the second obstacle-crossing part provide a climbing function. In addition, when the sweeping robot encounters obstacles or steps, the obstacle-crossing body can provide robot the function of the obstacle-crossing or climbing, thereby reducing the number of situations when the sweeping robot is trapped or unable to effectively climb upon encountering an obstacle or a steep road surface.

A mobile entity includes: a position decision unit configured to determine a position of itself; an environment information acquisition unit configured to acquire environment information at the position; and a motion determination unit configured to determine whether a motion scheduled to be performed holds based on the environment information. The environment information includes at least one of environment information related to a vocal apparatus and environment information related to a display device.

According to an embodiment, a robot includes a supporter disposed in the lower portion of a body to be spaced apart from a rear joint and a front joint and having a length shorter than a length of the rear joint and a length of the front joint; and a processor configured to perform a rear joint raising mode when a moved distance of the body is within a set distance or the body is stationary during driving of a front drive motor, and the rear joint raising mode is a mode in which a rear joint motor raises the rear joint such that a rear wheel which is connected to the rear joint is spaced apart from the ground.

The application discloses a modular robotic service vehicle (MRSV) including a chassis and body comprising one or more robotic arms and robotic legs with drive wheel providing stepping, walking and driving capability to transport passengers and/or cargo and a control system comprising kinematics equations providing real-time administration involving controlling one or more robotic legs and/or robotic arms to transition in a retracted position and/or in protracted position for achieving walking, driving, attaining and handling objects. Accordingly, an operator or a Network associating with providing real-time administration involving controlling motion and position of the MRSV according to an assignment relative for walking, driving, attaining and handling objects, and aiding or assisting a user.

A moving body manipulation system is provided. A master device that manipulates a slave device includes an upper body support portion mounted on a base and foot mounts. A control device controls an operation of the master device so that a lateral position of the foot mount on a free leg side follows a foot on a free leg side of a manipulator and the upper body support portion moves relatively with respect to the foot mount on a support leg side together with the base to change a tilt posture or up-down direction position of each foot mount in response to a floor shape on the side of the slave device when the manipulator performs a walking operation on the master device.

A load transporting apparatus may be steered while transporting a load across a base surface, and the load transporting apparatus may be operated hydraulically, electrically, or by use of an encoder. In particular, the load transporting apparatus may include a track configured to a saddle housing (a support movement for a movement assembly), and a foot that may be connected to the track. During load transport, the pad saver may be maintained in a substantially similar position relative to a frame structure supporting the load, even when the transport movement is not in a parallel direction to the orientation of the pad saver.
