Recently, during the advancement of the intelligent parking robot cooperation project with Saudi clients, the slope standard has become a core issue in technical alignment between both parties. Our company clearly proposed that the slope of the robot’s operating area shall not exceed 3 degrees (approximately equivalent to a 5% slope). This requirement, based on engineering logic and safety considerations, has become a key prerequisite for ensuring the smooth progress of the cross-border project.
To help Saudi clients understand clearly, our team focused on interpreting the core definition of a “3-degree slope”: first, the corresponding relationship between angle and slope—3 degrees is approximately equivalent to a 5% slope, meaning a 5-meter vertical rise for every 100 meters traveled horizontally; second, this parameter describes the inclination angle of the slope surface, not the ground clearance height directly required by the robot. Our technical director explained that the ground clearance height needs to be calculated via a formula in conjunction with the horizontal length of the slope, and the result directly determines whether the robot can pass safely.
A “3-degree slope” describes the inclination angle of the slope surface, rather than directly corresponding to the ground clearance height. The ground clearance height needs to be calculated in conjunction with the horizontal length of the slope.
The calculation formula is as follows:
h=L×tan(3° ) Where:
h = ground clearance height
L = horizontal length of the slope
tan(3° )≈0.0524
Examples:
When the horizontal length is 10 meters, the ground clearance height is approximately
10×0.0524=0.524 meters.
When the horizontal length is 100 meters, the ground clearance height is approximately
100×0.0524=5.24 meters.
Our company clearly informed the client that this requirement is not an excessive restriction, but a scientific conclusion based on equipment characteristics and scenarios, in line with international general standards, which can maximize the stable operation of the project.
At present, our company has submitted complete technical documentation on slope requirements to the Saudi client, and both parties have reached a preliminary consensus on the core requirements. In the follow-up, we will follow up on the renovation of the operating area and the equipment adaptation and commissioning work. This technical alignment not only demonstrates the professionalism and rigor of our company, but also accumulates valuable cross-border cooperation experience for expanding intelligent parking projects in the Middle East region.
