A magnetic cleaning device includes a handle unit, a main unit, and a deforming mechanism. The main unit includes a housing and a magnetic member. The deforming mechanism is connected between the handle unit and the main unit. The housing defines an accommodating space extending along an axis. The magnetic member is disposed in the accommodating space, and is movable along the axis between an attraction position, where the magnetic member is adjacent to an end of the housing, and a non-attraction position, where the magnetic member is away from the end of the housing. The main unit is movable relative to the handle unit via operation of the deforming mechanism.

A tool assembly includes a first selectively flexible tool including a first plurality of sequentially arranged links moveable between a slacked position and a tensioned position; and a second selectively flexible tool including a second plurality of sequentially arranged links moveable between a slacked position and a tensioned position, the second plurality of sequentially arranged links moveable over or through the first plurality of sequentially arranged links.

In a linear expansion mechanism, high rigidity is secured in all directions of orthogonal axes without any constraint on installation posture. The linear expansion mechanism includes: a block train made up of a plurality of blocks coupled along a coupling direction; a housing for containing the block train; a mechanism configured to deliver and draw the block train along the coupling direction; and a fixing mechanism configured to fix a relative position of a leading end position of the block train delivered from the housing relative to an entrance/exit position Pe located on the housing at which the block train enters and exits the housing with respect to directions orthogonal to the coupling direction of the block train.

A robot and a method of capturing an image applied to the robot, an electronic device for implementing the method of capturing the image, and a computer-readable storage medium are provided. The robot includes: a robot body; a workbench; a telescopic structure having one end pivotally connected to the robot body and the other end connected to the workbench; a driving mechanism arranged on the robot body and configured to drive the telescopic structure to extend, retract and/or move relative to the robot body; and an image capture device arranged on the workbench. The telescopic structure is configured to allow the image capture device to capture an image of a target object from different angles with the extension, retraction and/or movement of the telescopic structure.

A concentric tube steerable device includes a plurality of tubes having a nested, concentric configuration. The tubes include an outer tube and an inner tube that extends coaxially within the outer tube. The inner tube terminates at a tip, and a pose of the tip is effectuated through individual or collective rotation or translation of the tubes about a tube axis. The concentric tube steerable device includes an actuator for rotating at least one tube about a respective tube axis, and a translator for translating at least one tube along a respective tube axis. Each tube includes a precurved portion and a corresponding axis of precurvature. For at least one tube, a flexural rigidity of the tube along its axis of precurvature is less than a flexural rigidity of the tube along a second axis that is perpendicular to the axis of precurvature, thereby improving stability of the tube.

A transfer robot comprises a movable chassis, a door frame vertically arranged on the movable chassis, and a temporary storage mechanism and a cargo box conveying mechanism which are arranged on the door frame, wherein the temporary storage mechanism is provided with a plurality of temporary storage spaces used for temporarily storing cargo boxes, and the cargo box conveying mechanism can stretch horizontally and lift vertically relative to the door frame so as to convey the cargo boxes between the temporary storage space and a temporary inventory container.

A deployment mechanism and a delivery container enabling unattended delivery of cargo by a vehicle navigating autonomously on both vehicle lanes and pedestrian ways. A trailer for an autonomous vehicle for hauling additional cargo and power supplies. A method for delivering and picking up goods using delivery trucks, autonomous vehicles, and trailers. The deployment mechanism can include a crane, a robot arm, a forklift, straps, and sails. The delivery container can include visible, partly visible, or hidden security features and grasping features, and can be foldable and stackable. The trailer can include a 4-bar linkage, the 4-bar linkage enabling consistent pitch between the trailer cargo and a cargo hold of the towing vehicle. The trailer wheels are decoupled from the 4-bar linkage, connected by swing arms and possible shock absorbers. The trailer can buffer fore/aft movement of the trailer.

A demolition machine includes a deck having a front edge, a rear edge, a left side, and a right side, with the deck defining a central axis along a direction extending from the rear edge to the front edge and equally spaced from the left side and the right side of the deck, a drive assembly secured to the deck, with the drive assembly rotatable relative to the deck, an engine received by the deck and positioned at one of the left side and right side of the deck, an energy reservoir and hydraulic reservoir each received by the deck and positioned on an opposite side of the deck from the engine, and a boom assembly secured to a boom support structure of the deck. The boom assembly is moveable relative to the deck, with the boom support structure positioned on the central axis.

An object gripping mechanism is provided for use with a robotic arm. A robotic arm and method of manufacturing an object gripping mechanism are also provided. The object gripping mechanism includes an attachment modular configured to connect the object gripping mechanism to the robotic arm. The object gripping mechanism also includes a plurality of retractable arms each pivotably connected with the attachment modular. The object gripping mechanism also includes one or more movement mechanisms collectively configured to pivot the plurality of retractable arms to a desired position. The object gripping mechanism further includes a drive mechanism positioned within each of the plurality of retractable arms and configured to pivot the object engagement feature using a gear and timing belt configuration.

A boom arm assembly includes an anchoring portion for attachment to an anchoring surface, and a mounting portion for attachment to an auxiliary electrical device. A telescoping link includes an elongate outer member and an elongate inner member. The outer member has a first distal defining a ball joint which is connected to the anchoring portion or the mounting portion, and the inner member has a second distal end defining a ball joint connected to the anchoring portion or the mounting portion. The inner member telescopes within the internal through bore of the outer member. An internal through bore of the inner member and an internal through bore of the outer member align with each other to allow passage of the flexible elongate supply link from the anchoring portion to the mounting portion. A locking mechanism connects locking relative movement between the inner member and the outer member.
