Problems solved by technology

However, when the walking mechanism moves on the surface to be worked, it will inevitably slip, lose steps, etc.
When such a situation occurs, the traveling mechanism is still in operation, and the encoder device is still counting, but in fact, there is no mov

Embodiment Construction

[0020] The present invention provides a self-moving cleaning robot, which has simultaneous positioning and map creation to locate the current position and map features of the self-moving cleaning robot.

[0021] The present invention takes a cleaning robot as an example to describe the present invention in detail. Such as figure 1 Shown is a schematic diagram of the overall structure of a specific embodiment of the invention---a cleaning robot. Such as figure 1 Shown is a block diagram of the control structure of the present invention. combine figure 1 with figure 2 As shown, the cleaning robot includes a robot body 1 , a control unit 2 , a drive unit 3 , a walking unit 4 and a functional unit 5 , and the control unit 2 is located in the body of the robot body 1 . The control unit 2 drives the traveling unit 4 to rotate through the driving unit 3, and the traveling unit 4 drives the robot body 1 to move. The functional unit 5 is a cleaning unit.

[0022] The cleaning r...

Abstract

The invention discloses a device for realizing simultaneous positioning and map building of an indoor service robot and the indoor service robot with the device. The device comprises an external sensor, an internal sensor and an information processing module, wherein the robot moves in an external environment, the measured data of the external sensor and the internal sensor is recorded, and the characteristics of the environment are extracted, so a posture and a characteristic map of the robot are obtained by recursive prediction and an updating algorithm; and the corresponding posture and characteristic map are updated under the condition of meeting the characteristic matching. By placing the moving robot in an unknown environment and combining the positioning and the map building into a whole, the device allows the robot to incrementally build a continuous map of the unknown environment and simultaneously determine the position in the map thereof; and thus the one-time working efficiency is effectively improved, the autonomy of the self-moving indoor service robot is improved and the intelligence level of the robot is further prominent.

Description

technical field [0001] The present invention relates to an intelligent device, in particular to a device for realizing simultaneous positioning and map creation of an indoor service robot. The indoor service robot specifically relates to a cleaning robot, a security robot and the like. Background technique [0002] With the continuous improvement of the level of science and technology and people's living standards, the self-mobile indoor service robot came into being and has been gradually accepted by people. While the robot is moving by itself, it provides services for people through its built-in functional units, saving The characteristics of time-saving and labor-saving work have been recognized by people, and thus widely used in office and home environments. [0003] Most of the self-mobile indoor service robots currently on the market are cleaning robots, which include: drive components, rechargeable energy supply units and control units. Under the control of the contr...
