Abstract: A wheel assembly for a remote vehicle comprises a wheel structure comprising a plurality of spokes interconnecting a rim and a hub. The spokes comprise at least one slit extending therethrough radially inward from the rim to the hub. The assembly also comprises a flipper structure comprising an arm, a plurality of legs, and an attachment base. The plurality of legs and the attachment base comprise a four-bar linkage. The assembly further comprises an insert comprising a bore with a flat surface that tapers outward from a top portion to a bottom portion of the insert. The insert being configured to couple the flipper structure to the wheel structure via an axle on the remote vehicle and prevent backlash between the axle and the flipper structure. The flipper structure being configured to transmit axial forces to the wheel structure. The wheel structure being configured to absorb radial and axial forces.

Abstract: A method of operating a robot includes electronically receiving images and augmenting the images by overlaying a representation of the robot on the images. The robot representation includes user-selectable portions. The method includes electronically displaying the augmented images and receiving an indication of a selection of at least one user-selectable portion of the robot representation. The method also includes electronically displaying an intent to command the selected at least one user-selectable portion of the robot representation, receiving an input representative of a user interaction with at least one user-selectable portion, and issuing a command to the robot based on the user interaction.

Abstract: A method of operating a remote vehicle configured to communicate with an operator control unit (OCU) includes executing a click-to-drive behavior, a cruise control behavior, and a retro-traverse behavior on a computing processor. The click-to-drive behavior includes receiving a picture or a video feed and determining a drive destination in the received picture or video feed. The cruise control behavior includes receiving an absolute heading and velocity commands from the OCU and computing a drive heading and a drive velocity. The a retro-traverse behavior includes generating a return path interconnecting at least two previously-traversed waypoints of a list of time-stamped waypoints, and executing a retro-traverse of the return path by navigating the remote vehicle successively to previous time-stamped waypoints in the waypoints list until a control signal is received from the operator control unit.

Abstract: The present teachings provide a method of controlling a remote vehicle having an end effector and an image sensing device. The method includes obtaining an image of an object with the image sensing device, determining a ray from a focal point of the image to the object based on the obtained image, positioning the end effector of the remote vehicle to align with the determined ray, and moving the end effector along the determined ray to approach the object.

Abstract: A method of operating a mobile robot includes driving the robot according to a drive command issued by a remote operator control unit in communication with the robot, determining a driven path from an origin, and after experiencing a loss of communications with the operator control unit, determining an orientation of the robot. The method further includes executing a self-righting maneuver when the robot is oriented upside down. The self-righting maneuver includes rotating an appendage of the robot from a stowed position alongside a main body of the robot downward and away from the main body, raising and supporting the main body on the appendage, and then further rotating the appendage to drive the upright main body past a vertical position, causing the robot to fall over and thereby invert the main body.

Abstract: A system includes an operator control unit having a point-and-click interface configured to allow the operator to control the remote vehicle by inputting one or more commands via the point-and-click interface. The operator control unit displays a 3D local perceptual space comprising an egocentric coordinate system encompassing a predetermined distance centered on the remote vehicle, a remote vehicle representation having selectable portions, and an icon at a point selected in the 3D local perceptual space and at a corresponding location in an alternative view of a map having an identified current location of the remote vehicle. The system also includes a payload attached to the remote vehicle. The payload includes a computational module and an integrated sensor suite including a global positioning system, an inertial measurement unit, and a stereo vision camera.

Abstract: A robotic vehicle (10,100,150A,150B150C,160,1000,1000A,1000B,1000C) includes a chassis (20,106,152,162) having front and rear ends (20A,152A,20B,152B) and supported on right and left driven tracks (34,44,108,165). Right and left elongated flippers (50,60,102,154,164) are disposed on corresponding sides of the chassis and operable to pivot. A linkage (70,156,166) connects a payload deck assembly (D1,D2,D3,80,158,168,806), configured to support a removable functional payload, to the chassis. The linkage has a first end (70A) rotatably connected to the chassis at a first pivot (71), and a second end (70B) rotatably connected to the deck at a second pivot (73). Both of the first and second pivots include independently controllable pivot drivers (72,74) operable to rotatably position their corresponding pivots (71,73) to control both fore-aft position and pitch orientation of the payload deck (D1,D2,D3,80,158,168,806) with respect to the chassis (20,106,152,162).

Abstract: An articulated tracked vehicle that has a main section, which includes a main frame, and a forward section. The main frame has two sides and a front end, and includes a pair of parallel main tracks. Each main track includes a flexible continuous belt coupled to a corresponding side of the main frame. The forward section includes an elongated arm. One end of the arm is pivotally coupled to the main frame near the forward end of the main frame about a transverse axis that is generally perpendicular to the sides of the main frame. The arm has a length sufficiently long to allow the forward section to extend below the main section in at least some degrees of rotation of the arm, and a length shorter than the length of the main section. The center of mass of the main section is located forward of the rearmost point reached by the end of the arm in its pivoting about the transverse axis.

Abstract: The present teachings relate generally to a small remote vehicle having rotatable flippers and a weight of less than about 10 pounds and that can climb a conventional-sized stairs. The present teachings also relate to a small remote vehicle can be thrown or dropped fifteen feet onto a hard/inelastic surface without incurring structural damage that may impede its mission. The present teachings further relate to a small remote vehicle having a weight of less than about 10 pounds and a power source supporting missions of at least 6 hours.
