Abstract:
A three-wheeled remotely controlled vehicle is provided whose direction, speed and braking are automatically controlled by a remote transmitter. The signal from the transmitter is radiated to an electronic power control unit on the vehicle, and the power control unit causes a control to be exerted on the rear wheels of the vehicle. The front wheel of the vehicle is swivelly mounted to be freely rotatable about a vertical axis. The direction, speed and braking of the vehicle are controlled by individually controlling the rotation and direction of rotation of the rear wheels of the vehicle independently of one another.

PROBLEM TO BE SOLVED: To provide a following type mobile robot that can safely and appropriately follow a target object. SOLUTION: The mobile robot 2 that follows a target object 1 moving on a linear path L T of movement at a speed V T is controlled for movement such that the following path L R of the mobile robot 2 is parallel to the path L T of movement of the target object 1, and that a linear path vertically away from the path of movement of the target object by a certain amount dr or dl is set as a following path L R1 or L R2 so that the robot moves along the following path L R1 or L R2 .

Abstract:
An automated object following system includes a tracker associated with a following device, and a guider associated with an object to be followed. The tracker includes a first processor, and at least two transducers for generating an encoded ultrasonic signal. Each transducer has a control input communicating with the first processor for emitting an encoded ultrasonic signal generally toward the guider in response to a command signal from the first processor. The encoded ultrasonic signals carry signal source identification information. A radio frequency (RF) receiver communicates with the first processor for receiving from the guider an encoded RF signal carrying distance and direction information of the guider relative to the tracker to be used for steering the following device toward the object to be followed.
Abstract:
A control apparatus for a self-moving cart is disclosed, in particular a golf caddy, comprising at least a speed control of a motor onboard the cart and a logical control unit which adjusts said speed control of said motor based on the relative position of a reference user, furthermore comprising a proximity detection device meant to face the rear side of the cart, with respect to the travelling direction, so as to detect a relative distance with respect to a user following the cart, said logical control unit being configured so as to determine said speed control depending on said detected relative distance so that it is maintained in a tolerance range defined by a maximum distance and a minimum distance, wherein said minimum distance is such as to enable the user to operatively reach on/off means of said apparatus meant to be installed onboard said cart.
Abstract:
A foldable cart assembly which is arranged to provide trackable transportation to a product or a person. The cart contains sensors and computer-controlled drive wheels to enable that cart assembly, when fully opened, to follow a safe path as directed by received electronic signals. That cart assembly is also tri-foldably collapsible, so as to have multiple portions pivoted into nesting configuration with one another thus containable in a minimal volume and even carried by an individual.
Abstract:
The present invention provides a system and method of controlling a vehicle. The method includes the steps of: Providing a transmitter arranged to transmit in the microwave frequency range; providing a receiving means on the vehicle, receiving the signal, and calculating the azimuth of the transmitter with respect to the vehicle. The vehicle is controlled based on the calculated azimuth.
Abstract:
The present invention is directed to a self propelled robotic vehicle that will faithfully follow a portable receiver at a defined distance. The vehicle can sense an impending collision with a solid object in its path and will stop prior to collision. The vehicle will observe objects that are parallel to its course and if within a distance of

The invention concerns a golf buggy and a mobile transmitter unit which is carried by the golfer. The buggy and the transmitter unit each comprise a receiver¥and¥evaluating¥unit¥provided¥with¥a¥computer¥for¥a¥satellite-controlled¥positioning¥system.¥The¥two¥receiver¥and¥evaluating¥units¥calculate¥the¥respective¥position¥of¥the¥golfer¥and¥the¥buggy¥from¥the¥signals¥received¥cyclically¥from¥the¥satellite¥system.¥The¥mobile¥transmitter¥unit¥is¥provided¥with¥a¥high-frequency¥hand-held¥transmitter¥by¥means¥of¥which¥the¥positions¥of¥the¥golfer¥can¥likewise¥be¥transmitted¥cyclically¥to¥the¥buggy.¥In¥each¥case¥the¥buggy¥computer¥calculates¥the¥direction¥and¥distance¥of¥the¥golfer¥and¥stores¥these¥data¥until¥it¥travels¥the¥stored¥path¥in¥response¥to¥a¥signal.¥The¥buggy¥remains¥at¥a¥predetermined¥distance¥from¥the¥golfer.¥If¥a¥stationary¥reference¥transmitter,¥which¥corrects¥the¥golfer¥and buggy position data received from the satellite system, is also used, given areas of the golf course can be blocked off as areas in which the buggy may not travel.
