A method and system for a robotic device comprising a propulsion mechanism, an orientation sensor, a stored digital map of a service area, a sensor for sensing objects, a navigation and orientation system, and a processing facility comprising a processor and a memory, the processing facility causing the robotic device to determine and store a pose position of the robotic device at a plurality of sequential locations as the robotic device is guided by a user along a path from a start location to an end location through the service area, and as commanded by the user and utilizing the navigation and orientation system, re-trace the path from the start location to the end location replicating the stored pose position of the robotic device at the plurality of sequential locations.

Disclosed is a device for absorbing and marking a potentially dangerous substance on the ground, the device including: an elongate hollow body, the inner walls of which define a storage space in which a powder is stored which is capable of absorbing the substance when the powder comes into contact with the substance, the storage space leading into an opening for pouring the powder onto the substance in order to neutralize the substance, a base on which the lower end of the body is directly or indirectly mounted, the base projecting laterally relative to the body so as to form a marker in order to position the device on the ground in a stable manner and to mark the presence of the absorbed substance on the ground.

A mobile vehicle, a ground treating equipment and an orientation adjusting method thereof are provided. The ground treating equipment includes a frame, a ground treating unit, a connecting rod set, a connecting rod driving unit, a rotation driving unit, two pressure sensors and a controller. The ground treating unit is mounted at the frame. Two ends of the connecting rod set are connected to the frame and the mobile vehicle. The connecting rod driving unit is mounted at the connecting rod set for adjusting the orientation of the connecting rod set. The rotation driving unit is mounted between the frame and the connecting rod set for driving the frame to rotate relative to the connecting rod set. The pressure sensors are mounted at the frame for sensing two pressure values between the frame and ground, or the pressure sensors are mounted at the rotation driving unit for sensing two pressure values while the frame is driven to rotate clockwise and counter-clockwise. The controller is configured to control the connecting rod driving unit and the rotation driving unit for changing the two pressure values.

A manure collecting vehicle includes: a manure collector having a manure collection port and at least one powered rotational manure conveyer to convey manure to the manure collection port as the vehicle drives through the manure; a manure holding tank in manure communication with the manure collection port, collected manure passing through the manure collection port into the manure holding tank as the vehicle drives through the manure; and, an air system to create an air pressure differential between inside the manure holding tank and outside the manure holding tank when the vehicle is driving through the manure to be collected so that the collected manure passes from the manure collection port into the manure holding tank under influence of the air differential.

A self-moving snow removal device and a safe snow throwing method protecting a human or an object from damage by snow or miscellaneous matter. The snow removal device includes: a moving module, driving the snow removal device to move; a working module, including a working motor and a snow throwing mechanism, where the snow throwing mechanism is driven by the working motor to collect accumulated snow and miscellaneous matter on the ground and throw the accumulated snow and miscellaneous matter out of the snow throwing mechanism, and a maximum height of a thrown object in the air from the ground is referred to as a snow throwing height; and a control module, configured to control the working module or the moving module to enable the snow throwing height to be less than a predetermined snow throwing height threshold.

A road debris detection system includes a data processor in wireless communication with a base facility, the base facility including a plurality of aerial response vehicles adapted to be deployed from the base facility, each of the plurality of aerial response vehicles being specialized to perform specific tasks, the data processor adapted to receive data related to a roadway, assess if debris is present within the roadway, and when debris is present within the roadway assess the nature of the detected debris, select an aerial response vehicle from the plurality of aerial response vehicles at the base facility that is specialized to remove/move the detected debris and is capable based on the type, size and weight of the detected debris, and deploy the selected aerial response vehicle to clean-up the debris.

The invention discloses a system for vacuuming waste having a motor module and a waste module. The motor module has an open receiving area, motor, battery, vacuum tube receiving area and handle. Multiple bag hooks are spaced along the open receiving area. Disposable bags, having a drawstring within a channel, are placed within the waste module. The drawstring has a length greater than the bag perimeter to form multiple bag loops that extend through gaps in the channel. An insert maintains the bags in an open position. The bag loops are placed on the bag hooks so that when the motor module is opened, the drawstring pulls the bag closed.

A grass comb for feces removal made up of a body, a control panel connected to the body, the panel having a first lever and a second lever, a grate, the grate connected to the first lever and the body, the grate having a raised position and a lowered position, and the state of the grate responding to a user input on the first lever, a scraper connected to the body and operably connected to the second lever, wherein the scraper is oriented such that it can move from a first position to a second position according to user input on the second lever, wherein when the grate is in the raised position, moving the scraper from the first position to the second position pushes feces off the grate and into a bag.

Generally speaking, robotic pet walker is a self propelled apparatus for walking and entertaining canine pets in the absence of its owner. The robotic pet walker is able to travel programmed travel routes, dispense treats, scoop waste, and interactively play fetch autonomously or by control of the pet owner via internet and GPS. An LCD screen can display live video of the pet owner and a speaker can broadcast the voice of the owner to interact with the pet.

The absorbent spreader is the only product of its kind that is specifically designed to make spreading maintenance absorbents a cleaner and faster task, saving consumers time and energy usually spent from traditional methods. The absorbent spreader is uniquely designed with a release button enabling users to precisely control where to drop the clay, ensuring no accidental messes or unnecessary waste of clay during task work.
