Portable remotely controlled riding following robot

Abstract

The invention provides a portable remotely controlled riding following robot small in volume, light in weight and convenient to carry. The portable remotely controlled riding following robot comprises a vehicle body, wherein a driven wheel and a driving wheel with a hub motor are respectively mounted on the two sides of the vehicle body, a front video camera, a front lamp and a front ultrasonic sensor are arranged on the front of the vehicle body, and a rear lamp, a rear video camera and a rear ultrasonic sensor are arranged on the rear of the vehicle body. Due to the adoption of the motion sensing control of a gravity center of a human body, the two hands are liberated, control is flexible, the distance between the robot and a mobile phone of a user can be detected through two bluetooth modules, and a following function is realized. The portable remotely controlled riding following robot not only can be ridden by people, but also is combined with the remote control and following functions of the robot. The wheel type embodiment is suitable for indoor and flat road surfaces, the crawler type embodiment can pass uneven road surfaces, and the embodiment with swing arms can also climb up and down ladders and cross obstacles.

AI Technical Summary

Problems solved by technology

[0003] Professional robots cannot carry people, but balance vehicles, electric vehicles, electric scooters, etc. that can carry people generally weigh more than 20kg, and small balance vehicles exceed 10kg. Not only are they heavy and large in size, they are not easy to carry

And when encountering obstacles such as steps, people need to pick them up to pass. As a means of transportation, it is not convenient to use

[0004] The self-balancing car represented by segway uses photoelectric sensors to detect whether someone is standing on the car. The photoelectric sensors currently used are large in size and are not conducive to miniaturization. This is one of the many reasons why the self-balancing car is not portable.

In addition, for good passability, all self-balancing vehicles use large wheels of more than 6 inches and large hub motors, which also bring about the problem of being heavy and not portable.

[0005] Currently the lightest balance car on the market, such as the electric balance torsion car with patent number 201420314351.5, needs to connect two wheels through a hollow shaft, and detect the angle of the pedals on both sides to control the steering of the car body, which also brings mechanical structure Complicated, large size, not portable, etc.

[0006] In terms of control, all balance vehicles use a gyroscope system. The user can change the inclination angle of the pedals by leaning forward and backward slightly, and the gyroscope can detect the inclination angle of the pedals to realize forward, acceleration, and deceleration. , brakes and other driving operations, which requires that the pedals must be kept level at all times, while four-wheeled electric skateboards, or electric scooters with two front and rear wheels, although more stable, cannot maintain the level of the pedals when encountering uphill and downhill. Therefore, the gyroscope cannot be used to control the movement, and only the handle or a separate remote control can be used to control the movement of the car body, which also brings inconvenience to use

[0007] And almost all electric skateboards need a handheld remote control to control the speed and brakes, which is not convenient enough to use

[0008] For all the above reasons, the existing electric bicycles, electric balance cars, and electric scooters are relatively bulky, not portable, have limited ability to cross obstacles, cannot climb stairs, resulting in small application range and limited market space.
