A control device for an autonomous lawn mower is described which receives input signals from a first and/or second hand control and determines a control signal for controlling the autonomous lawn mower. The hand controls may provide for intuitive control of the mower by a user. The control signals may be used to operate the autonomous lawn mower to perform a task such that, when later detached or otherwise decoupled, the autonomous lawn mower may perform the same or similar tasks substantially autonomously based on data (e.g., sensor signals, control signals, etc.), generated during manual operation. In some examples, the control signals may be determined to aid a user in maintaining a straight mow, proximity to a desired pattern for mowing, and/or be otherwise altered based on the presence of a user.

A ground maintenance vehicle that includes: front steering wheels; rear drive wheels; a frame with a first and second pivot point; a single lever steering assembly with a single lever steering control, where the single lever steering assembly is coupled to the first pivot point; multi-axis articulating joint coupled to the second pivot point; a front caster steering assembly coupled to the multi-axis articulating joint; and where the front caster steering assembly and the multi-axis articulating joint simultaneously provide articulating and caster steering proportional to lateral movement from the single lever steering control.

A motorized wheel is connected to a single boom pivotally connected to a body having front wheels. The body carries a power supply for the motorized wheel in the form of batteries and a generator. A work piece is removably carried on the body by extending across horizontal supports or in a tray having pivot extrusions slideably received on attachment brackets while support extrusions abut with the horizontal supports. The body includes first and second frames including first, second and third legs extending at obtuse angles from each other and a handle extending between the third legs. The body further includes support components holding the first and second frames in a spaced, parallel relation and supporting the batteries and the generator. A sulky is slideably connected to the single boom and upon which a worker stands.

An articulated work machine with individually powered drive members. Each drive member is controlled by a corresponding electric motor, and is capable of rotating at a different speed and in the opposite rotational direction than all other drive members. Each drive member may also remain stationary while all other drive members rotate. The electric motors are commanded by a controller, which may be directed by inputs from by an operator. A lift arm extends from the front end of the vehicle, and a platform station extends from the rear end of the vehicle. The lift arm is connected to a tool, such as a bucket.

A vehicle has first and second parts with at least one road wheel. The first part pivotally connects to a connecting member at two spaced apart points to pivot about a first axis relative and the second part pivotally connects to the connecting member at two spaced apart points 18 to pivot about a second axis, which is perpendicular to the second axis, intersecting at a pivot point. A first drive shaft rotatably mounts to the first part and extends in a direction perpendicular to a longitudinal axis of the first part, a second drive shaft rotatably mounts to the second part and extends in a direction perpendicular to a longitudinal axis of the second part. The first and second drive shafts connect by a universal joint so that the two shafts to pivot relative to each other about the pivot point.

An articulating cart system which utilizes an articulating frame to effectively maneuver within tight spaces and a low-elevation platform to ease mounting and dismounting the cart. The articulating cart system generally includes a front frame and a rear frame. A platform is connected to the front frame so that the platform pivots or articulates along with the front frame with respect to the rear frame. A joystick controller may be provided which allows one-handed operation. One or more actuators may be connected between the rear frame and the front frame for pivoting the front frame with respect to the rear frame. A motor is provided to power the actuators and frame wheels. The platform is close to the ground to ease access for the operator. Utilizing the articulating frame, the present invention may traverse much tighter spaces and turns than is possible with previous cart systems.
