3. Environmental Requirements
Robots can only be used for transporting goods indoors.
The working temperature of the robot is 0 ℃~40 ℃, and the working humidity is 10%~90% (without condensation).
It is prohibited to use robots in environments with explosive hazards.
It is prohibited to use robots in environments with open flames.
The road section in the work area should be protected or marked with warning signs to remind other personnel of robot access.
The ground is flat, without grooves, damage, hollowing, oil stains, glue and other pollutants; There are no foreign objects such as screws, rag gloves, thread cables, etc. that are easy to get stuck and entangle the wheels.
Do not operate in excessively open areas (greater than the laser perception distance), such as long corridors.
It is prohibited to operate the robot in an environment with damage on the site to prevent the robot from bumping and causing the goods to roll over.
Ensure that the dimensions and heights of the alleyways, ceilings, etc. in the venue are appropriate, and ensure that there are appropriate gaps around the robot during operation.
Fluctuation degree: When the road surface undulation degree of the robot is below the maximum allowable value, the robot should be able to achieve controllable rated speed driving, and the undulation degree should be positioned as the difference between the highest and lowest heights within the reference range. The fluctuation degree is within 1m ² The maximum allowable value within the range should be less than 3mm (including 3mm).
Road slope: The road slope (H/L) is defined as the maximum ratio of the horizontal height difference of the road surface to the length of the route over a length range of 100mm. When the road slope of the robot is below the maximum allowable value, the robot should be able to achieve controllable rated speed driving. The maximum allowable value of road slope must be less than 0.03 (including 0.03), and for parking points that require precise positioning by robots, it must be less than 0.01 (including 0.01).
Step height: The definition of step height is the maximum difference in the horizontal height of the road surface within a length range of 100mm. When the height of the road steps on which the robot operates is below the maximum allowable value, the robot should be able to achieve controllable rated speed travel, but the robot's parking position does not allow steps to appear. The maximum allowable value of step height must be less than 5mm (including 5mm).
Gully width amplitude: Gully width amplitude is defined as the ability of the robot to achieve controllable rated speed travel when the width of the ditch on the road surface is below the maximum allowable value, but the robot's parking position does not allow grooves to appear. The maximum allowable value of the width of the road ditch should be less than 8mm (including 8mm). When the width of the ditch is greater than the maximum allowable value, the requirements should be based on the height of the steps.
Ground friction coefficient: The robot uses polyurethane material wheels, and the ground sliding friction coefficient should not be less than 0.5. Based on the need for safe braking distance and handling positioning accuracy, the size of the ground friction coefficient is extremely important. Whether it is ground dirt, water stains, or cleaning agents, they may have an impact on the robot's driving.
Ground load bearing: The load per unit area of the ground should be higher than the load per unit area within the horizontal projection area of the robot, and the ground should be kept intact and not withstand destructive damage. The pressure generated by the robot's walking on the ground should be effectively transmitted to the cement load-bearing layer, and composite ground is more suitable. The ground compression data should consider the load caused by the small area pressure of the wheels. There must be no hidden voids on the ground, regardless of their size, which may have serious consequences for the use of robots. The construction party needs to conduct a flaw detection on the surface layer of all areas where the robot travels, and the unqualified ground must be reworked to meet the standards.
Ground electrical characteristics: In order to avoid the accumulation of static electricity in the robot body (used in static sensitive environments), the ground conductive impedance of the robot driving on the road surface should be maintained at 106 to 109 ohms (refer to the German DIN51953 standard).
