A device for supporting and moving a load within an area may include a motive construct configured to support the load and move the load to a ground location within the area; a lift mechanism coupled to the motive construct, the lift mechanism being configured to effect movement of the motive construct to a height relative to the ground location; and a remote controller operatively coupled to the device via at least one of a cable connection and a wireless connection, the remote controller being configured to steer the motive construct and/or to control the lift mechanism. The device may further include at least one sensor to detect a characteristic of the load. The device may further include a braking system.

The invention relates to a sporting device (1), in particular a touring ski assembly. The sporting device (1) comprises a sliding body (2) on which a bottom side (3) is designed as a sliding surface (4). Furthermore, the sporting device (1) comprises a binding apparatus (6) disposed on the top face (5) of the sliding body (2) for fastening to a sporting shoe (7) of a user (8) in such a way that the fastening can be released as and when necessary, a circulating belt (13) having a first segment (14) for establishing a relative motion between the sliding body (2) and the ground (12) and a second, returning segment (15), as well as a drive apparatus (17) and at least one first deflecting apparatus (18) for the belt (13). The first segment (14) is disposed next to the bottom side (3) of the sliding body (2) and the second, returning segment (15) is disposed next to the top face (5) of the sliding body (2). At least the majority of the length (9) of the sliding body (2) is surrounded by the circulating, intrinsically closed belt (13). By means of this design, a user can be supported with regard to his advancing movement, in particular the overcoming of ascents and mountain routes can thereby be made easier, such that the body force or performance capacity to be applied by the user can be lower.

The present disclosure features standing electric vehicles for golf course travel that include a skateboard-like deck. The vehicles disclosed herein, referred to as golf boards, include features that enhance the safety and ease of use of the vehicle, including power-off electromagnetic braking systems.

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.

A pushcart includes a left wheel, a right wheel, a left wheel driver, a right wheel driver, a control unit, a left wheel rotary encoder, and a right wheel rotary encoder. The left wheel driver rotates the left wheel. The right wheel driver rotates the right wheel. The left wheel rotary encoder detects a rotational angle of the left wheel. The right wheel rotary encoder detects a rotational angle of the right wheel. The pushcart performs feedback control on angular velocities of the left wheel and the right wheel at least using an integral operation. The control unit calculates a weighted average of an integral element with respect to the angular velocity of the left wheel and an integral element with respect to the angular velocity of the right wheel, and then separately controls the left wheel driver and the right wheel driver based on the weighted average.

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.

The disclosed technology relate to a device and system that include an outdoor power equipment power unit or cart configured to releasably couple a number of different interchangeable attachments or work implements to a common power unit, where some attachments include and/or require operator presence control, while other attachments do not include and/or require operator presence control. The outdoor power equipment power unit includes a power transfer coupling member operatively coupled to the drive shaft and configured to transfer rotational power to the associated attachment; and an operator presence actuation member operatively coupled to the operator presence control member, the operator presence actuation member configured to rotate in response to user actuation of the operator presence control member.

Disclosed is a self-powered vehicle utilized in the field of agriculture, property maintenance, landscaping for use with estate or condominium ground maintenance. It is used for spraying pesticides, herbicides, fertilizer and the like and also for application of similar products in granular form, but further serves as a maintenance platform around a larger industrial facility. Its main payload area is also used for cargo and product transport. It offers high mobility and maneuverability. It is powered with gearhead motors connected to its drive wheels with batteries as its power source. They are charged by an engine driven generator all of which is mounted on the vehicle. Directional control is achieved by the use of a motorcycle handle bar in combination with rotary potentiometers. Each potentiometer controls pulse width of a pulse width modulator thereby controlling the speed of a gearhead motor. The vehicle is optionally a walk behind device but may be provided with a seat behind the handle bar.
