## Abstract

A mapping robot that includes a frame, two motorized wheels, for each motorized wheel, a motor which drives the wheel in rotation, a location system determining a position of the robot on a synthetic ground, a control unit arranged to collect position information delivered by the location system and information on electrical consumption of each motor, and to associate the electrical consumption information with the position information, and a friction element which has teeth which rub on the synthetic ground.

## Claims

### Claim 1

A system comprising a mapping robot, wherein the mapping robot comprises:
a frame,
at least two motorized wheels,
for each motorized wheel, a motor configured to drive the wheel in rotation,
a location system comprising a transmitter configured for determining a position of the robot on a synthetic ground,
a friction element comprising teeth configured to rub on the synthetic ground, thereby causing generation of electrical consumption by the motor, the electrical consumption being representative of a density of balls at a location,
a control unit comprising a processor arranged to collect position information delivered by the location system and information on electrical consumption of the motor, and
a display system comprising a screen, the display system being in communication with the control unit and being arranged to display the electrical consumption as a function of position information when the electrical consumption is above or below a set threshold in order to recognize density of balls with the position information.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the friction element is adjustable heightwise.

### Claim 3

A method comprising:
determining, using a location system comprising a transmitter, a position of a mapping robot on a synthetic ground, the mapping robot comprising (1) at least two motorized wheels, (2) teeth, and (3) for each motorized wheel, a motor configured to drive the wheels in rotation,
rubbing the teeth of the mapping robot on the synthetic ground, thereby causing generation of electrical consumption by the motor, the electrical consumption being representative of a density of balls at a location,
collecting (1) position information from the location system, and (2) information on electrical consumption of the motor, and
displaying the electrical consumption as a function of the position information when the electrical consumption is above or below a set threshold in order to recognize density of balls with the position information.
