Abstract: Stations for deployment, recharging and/or maintenance of a plurality of unmanned aerial vehicles (UAVs) are disclosed herein. Such deployment stations can be implemented in a container that includes a robotic arm and a conveyor system. The robotic arm can secure a UAV hovering outside the station, move the UAV inside the station, and transfer the UAV to the conveyor. The conveyor can couple to and move multiple UAVs. Further, charging systems may be integrated in such deployment stations to charge UAVs when coupled to and moving along the conveyer. Further, process pieces may be utilized to simplify mechanical and electrical interfacing between a UAV, the robotic arm, the conveyor, the charging system and/or other systems at the UAV station.

Abstract: An example system includes a vehicle, a light projector connected to the vehicle, and a control system. The control system is configured to determine a planned operating region for the vehicle within an environment. The control system is also configured to determine that the planned operating region is within a threshold distance of an object within the environment and, in response, determine a caution region to illuminate with the light projector near the object. The control system is further configured to cause the light projector to project an indication of the caution region near the object. The projected indication remains fixed in relation to the object as the vehicle moves toward the planned operating region.

Abstract: Example implementations may relate to a mobile robotic device that is operable to reorient a distance sensor using an adjustable leveler. According to these implementations, the robotic device may determine a height map indicating surface elevation data for a ground surface on which the robotic device is travelling within an environment. Then, the robotic device may determine a current location of the robotic device relative to the height map. Based on the current location, the robotic device may determine a current spatial orientation of the distance sensor relative to the ground surface. Further, the robotic device may (i) determine an adjusted position of the leveler to which the leveler is movable to cause the distance sensor to spatially reorient from the current spatial orientation to a target spatial orientation and (ii) cause the distance sensor to reorient to the target spatial orientation by moving the leveler to the adjusted position.

The control system may be configured to determine a target velocity for the motor. The control system may be additionally configured to determine a target position that, when commanded to the motor controller, is predicted to cause the motor controller to drive the motor with the target velocity at a target time point by driving the motor with the characteristic acceleration profile. Further, the control system may be configured to provide an instruction for execution by the position-controlled motor controller, the instruction may be configured to cause the motor controller to drive the motor to the target position.

Abstract: Ribbon packaging is used to load the ribbon into the printer and to code the media type into the printer. The inventive ribbon packaging comprises a contoured sleeve that acts as a loading device. The contoured sleeve with printer ribbon is inserted into the printer. The contoured sleeve is withdrawn and the printer ribbon is left in the installed position in the printer. The packaging also has coding that can be read by the printer's electronics and coded in to the printer software, thereby automatically setting up the media type.

Abstract: A mobile base movable relative to a surface is disclosed. The base includes a main housing having at least two wheels pivotably and rotatably mounted to the housing with each wheel having a steering axis and a rotation axis. The steering and rotation axes are nonintersecting and are offset by a known caster distance. Further, included are drive means for rotating the wheels to roll along the surface, steering means for pivoting the wheels and changing their heading with respect to the surface, and controller means for reading an input vector from a host processor. The input vector is a three dimensional force torque vector.

Abstract: An arrangement for a printer, which printer comprises a chassis to which a print mechanism (3) as well as a feed mechanism comprising a print roller (4) are mounted for printing on and feeding of a printing material. The arrangement is characterized by said chassis comprising a central piece (1) in which said roller (4) is mounted only at one of its ends (12), whereby the roller (4) at its other end (11) is freely suspended in relation to the chassis.

Abstract: A drive system base or platform, such as for a mobile robot, is disclosed having multiple caster wheels, each wheel having its own first motor for independent driving and its own second motor for independent steering. Each wheel is rotably and pivotably mounted in a separate wheel module, which includes both the driving and steering motors associated with the wheel. All of the wheel modules on the base are identical and interchangeable. The two motors of each module are mounted side by side in a vertical arrangement for compactness. Each wheel module includes a suspension for allowing each wheel to move vertically and independently relative to the base. The hub and tread of each wheel are each cast concentrically around a bevel drive gear in an offset manner to provide a wheel and bevel gear that turn more smoothly and precisely.

Abstract: The invention relates to an arrangement for mounting a print head in a printer. The arrangement comprises a frame (1) to which a feeder device feeds a material to be printed which the printer will print on by means of a print head (3), movably arranged adjacent to a print roll (2) for being brought into, or out of, contact with the material to be printed. According to the invention, the arrangement uses a magnet (5) to hold the print head. Preferably, the print head is fitted in a fixture device (4), which is pivoting freely around a rear axle (7) parallel to the print roll, and the pressure is applied on the print head by a pressure member (6). The magnet (5) is preferably attached to the pressure member (6) so as to transfer pushing as well as pulling forces. The invention enables screws or fixed mounting of the print head to be avoided. The arrangement according to the invention also allows for the print head (3) pressure point to be transversally displaced.
