The calculation process of the rolling robot crossing the steps is shown in fig. 5, and the front and back states of the rolling robot crossing the steps are shown in fig. 6 and 7. When the height of the step does not exceed the radius of the shell, a contact point between the shell and the step is set as a point A, a contact point between the shell and the ground is set as a point B, the radius of the shell is R, the height of the step is h = xR, the value range of x is 0 to 1, the distance from the point B to a ground projection point of the point A is d, after the shell spans the upper step, the distance from the center to the point B is L, and the included angle between the telescopic arm and the ground vertical line is theta.
And calculating to obtain the distance from the point B to the ground projection point of the point A as follows:
from the above formula, after the housing spans the upper step, the distance from the main shaft of the housing to the point B:
when x is a maximum of 1, the distance between the extension end 12 of the telescopic arm and the main shaft is a maximum of 2.236R.
The angle theta of the telescopic arm and the angle ground vertical line after completely crossing the step is calculated as follows,and obtaining a derivative:when x =0.5, θ takes a maximum value of 30 °.
tan30 degrees is approximately equal to 0.5774, so if the friction coefficient of the contact point B is larger than 0.5774, the friction force can be self-locked, the telescopic arm cannot slip, and enough lifting force is provided to enable the rolling robot to cross steps.
Therefore, if a step with the same height as the radius of the shell needs to be crossed, when the telescopic end 12 of the telescopic arm is in the maximum extension stroke, the distance between the end point of the telescopic end 12 of the telescopic arm and the main shaft is more than 2.236 times of the radius of the shell of the rolling robot, the overall length of the telescopic arm in the retraction state is less than the diameter of the shell of the rolling robot, the extension end 12 of the telescopic arm is provided with a friction block, the friction coefficient of the friction block and the ground contact point is not less than 0.5774, the axial force of the telescopic arm is different according to different self weights of the shell, and the axial force of the telescopic arm in the embodiment is more than 1000N. The steering engine 11 does not need to be powered constantly to keep a specific angle, and only self-locking is realized through friction force, so that resultant force passes through the main shaft to lift the shell.
When the height of the step exceeds the radius of the shell, the extension end of the telescopic arm extends to lift the shell, the shell rolls upwards along the vertical side wall of the step until the shell contacts with the edge of the step to form a point A in the calculation process, and when the maximum extension stroke of the telescopic end 12 of the telescopic arm exceeds more than 2.236 times of the radius of the shell of the rolling robot, the rolling robot can theoretically climb over the step with the height exceeding the radius of the shell. In practical tests, a shell with a radius of 20cm can be overturned over a step with a height of 22 cm.
And a control system and a power supply module are also arranged in the shell, the control system comprises a dynamic state sensor and a PID controller, the dynamic state sensor is used for detecting the real-time dynamic state of the robot and the driving system, and the sensor comprises a GPS, at least one gyroscope, at least one acceleration sensor and a coded disc.

And their respective detection data are transmitted by wire or wirelessly to the control unit or an external remote computer for further processing. The power module can supply power for the main shaft driving device, the auxiliary shaft driving device, each control system and the telescopic arm.
When the rolling robot rolls on a flat ground or a gentle slope normally, the telescopic arm is in a contraction state, and the telescopic arm rotates to be parallel to the auxiliary shaft, so that the rolling of the rolling robot is not influenced; when the device crosses a step, the main shaft rotates to drive the inner swing block to swing towards one side of the step to enable the shell to be attached to the step and always remain attached to the step, the extension end of the rotary telescopic arm extends downwards, the extension end of the telescopic arm extends to abut against the bottom surface to continuously lift the shell, the relative height difference between the bottom surface of the shell and the step is continuously reduced, when the driving force of the inner swing block is enough to overcome the relative height difference between the bottom surface of the shell and the step, the shell continuously rolls over the step, at the moment, the telescopic arm retracts and rotates to be parallel to the auxiliary shaft, and the rolling robot returns to normally roll.
