Autonomous painting robot

Abstract

The present utility model relates to an autonomous interior painting robot for homes, commercial premises, hotels, etc. The robot is designed for painting and outlining while recognizing obstacles in the work area and aimed at reducing the efforts and time needed to carry out these operations. It is applicable in the field of interior design and the completion of small conditioning works. The autonomous painting robot comprises a mobile base (1) equipped with a paint tank and a pump or compressor, characterized in that the base (1) comprises a series of detectors configured to locate the base (1) and to detect obstacles, a substantially vertical lifting column (4), at the end of which a robot arm (5) is articulated and topped with a head (6) that carries a paint gun (7) connected to the pump, one or more cameras (9), and a proximity sensor (10).

Claims

1. An autonomous painting robot comprising: a mobile base equipped with a paint tank and a pump or compressor, the base (1) comprising a series of detectors configured to locate the base and to detect obstacles, a substantially vertical lifting column, at the end of which a robot arm is articulated and topped with a head that carries a paint gun connected to the pump, one or more cameras, and a proximity sensor, wherein the head carries a retractable spatula.

2. The robot of claim 1, wherein the base further comprises omnidirectional wheels.

3. The robot of claim 1, wherein the paint gun is of the “airless” type.

4. The robot of claim 1, wherein the one or more cameras each comprises lighting sources.

Description

DESCRIPTION OF THE DRAWINGS

(1) For a better understanding of the invention, the following figures are included.

(2) FIG. 1: front view of an embodiment of the device, with the robot arm folded.

(3) FIG. 2: side view of the previous exemplary embodiment, with the robot arm deployed.

(4) FIG. 3: detail of an example of a head.

EMBODIMENTS OF THE INVENTION

(5) Next, an embodiment of the invention will be briefly described as an illustrative and non-limiting example thereof.

(6) The robot shown in the embodiments of the figures comprises a mobile base (1), for example comprising four omnidirectional wheels (2), of the “mechanum wheel” type. These wheels (2) allow movement in any direction to allow getting closer to the area to be painted. It also includes a series of laser, visual detectors to locate and detect obstacles. For example, it is equipped with infrared detectors around the base (1) to detect and avoid obstacles and room boundaries.

(7) The base (1) supports a lifting column (4), for example, telescopic, which is arranged in a substantially vertical direction. A robot arm (5), articulated and topped with a head (6) that carries a paint gun (7), is provided at the top of the lifting column (4). The gun (7) is preferably of the “airless” type to reduce possible stains.

(8) The head (6) also carries a retractable spatula (8). It is intended to outline ceilings, window frames and baseboards.

(9) One or more cameras (9) in the head (6), ideally each with light sources, and a proximity sensor (10) allow to recognize the surfaces to be painted and outlined. A color detector allows to recognize whether the passage of the gun (7) was sufficient or it is necessary to retouch. The color detector may operate independently or by programming from the images of the cameras (9).

(10) The base (1) comprises a paint tank and a pump or compressor to bring it up to the gun (7) through a suitable tube, attached to the robot arm (5). The tank is removable to facilitate the change of paint, its cleaning and that of the pump or compressor.

(11) All of the above elements are powered by one or more batteries, by a wiring connected to the network, or by both solutions.
