A mobile robot charger can have one or more charger electrical contacts. A shroud can be movable between a closed position and an open position, and can be configured to cover the charger electrical contact(s) in the closed position and to expose the charger electrical contact(s) in the open position. The shroud can be configured to move from the closed position to the open position when the mobile robot engages the charger. A switch, such as a momentary switch, can be movable between an off position and an on position, and can be moved from the off position to the on position when the mobile robot engages the charger. One or more electromagnetic switches (e.g., reed switches) can have an on configuration and an off configuration, and can be turned to the on configuration by one or more magnets on the mobile robot when the mobile robot engages the charger.

To prevent scattering of scattered objects such as of water, sand, mud, or snow accompanied by movement.

Scattering prevention constraint information is acquired based on road surface information. Movement is controlled based on the scattering prevention constraint information. For example, vibration information is detected by a vibration sensor or the like, and road surface information (information such as a road surface depth and a road surface type) is acquired based on the vibration information.

A dispenser tool (42) is provided with multiple cartridges for dispensing viscous material onto the surface (5′) of a wind turbine blade (5). The dispenser tool (42) is advantageously part of a robot system used to work the surface (5′) of the blade (5). The system is configured for bringing the nozzle of a selected cartridge into the vicinity of the surface (5′) and orienting the dispenser tool (42) relatively to the surface (5′) such that the nozzle (46) of the corresponding selected cartridge (44) is at the surface (5′) for providing viscous material onto the surface (5′) from the selected cartridge (44) while moving the nozzle (46) along the surface (5′).

A robot has a main body frame, an elastic body that forms a closed space between the elastic body and the main body frame, a movement mechanism that has a surface that is grounded when moving, and which is provided so as to be able to be housed in the closed space, and a drive mechanism that causes the movement mechanism to advance to an exterior of the closed space or to retreat into an interior. The elastic body elastically transforms owing to a pressing force received in accompaniment to an advancing of the movement mechanism, increasing the size of an aperture portion for exposing the movement mechanism, and elastically recovers in accompaniment to a retreat of the movement mechanism, reducing the size of the aperture portion.

A walking vehicle including a chassis and a plurality of wheel-leg components is described. The plurality of wheel-leg components are collectively operable to provide wheeled locomotion and walking locomotion.

An article handler for attachment to a front end loader, the article handler comprising a support body and a jaw assembly, the support body comprising a proximal end adapted for attachment to the front end loader, and a distal end adapted for attachment of the jaw assembly. The article handler may be adapted to handle, install, and dismount ground engaging tools (GET), such as teeth for excavating buckets.

Methods and systems for joint execution of complex tasks by a human and a robotic system are described herein. In one aspect, a collaborative robotic system includes a payload platform having a loading surface configured to carry a payload shared with a human collaborator. The collaborative robotic system navigates a crowded environment, while sharing a payload with the human collaborator. In another aspect, the collaborative robotic system measures forces in a plane parallel to the loading surface of the payload platform to infer navigational cues from the human collaborator. In some instances, the collaborative robotic system overrides the navigational cues of the human collaborator to avoid collisions between an object in the environment and any of the robotic system, the human collaborator, and the shared payload.

A position and tracking system for radio-based localization in an operating room, includes a receiver, a mobile cart, a processor, and a memory coupled to the processor. The mobile cart includes a robotic arm and a transmitter in operable communication with the receiver. The memory has instructions stored thereon which, when executed by the processor, cause the system to receive, from the transmitter, a signal including a position of the mobile carts in a 3D space based on the signal communicated by the transmitter and determine a spatial pose of the mobile carts based on the received signal.

Provided is a robot including a main body provided with a pair of traveling wheels that are spaced apart from each other in a horizontal direction, a seating body disposed above the main body, a foot supporter disposed on a front lower portion of the main body, at least one front wheel disposed on the foot supporter, and a rear wheel disposed on the main body so as to be closer to a rear end of the main body than a front end of the main body and the traveling wheel is closer to the front end of the main body than the rear end of the main body.
