Is autonomous mobile robot safe?

The safety of people and the reliability of MOBOT® AGV mobile robots are key to us. We always analyze the potential risks before implementing the system to minimize any threats, such as possible collisions, as well as such as interruption of the task or delays in their performance.

The first element is the safety system of the robot itself. MOBOT® AGV works have been designed in accordance with the applicable standards and can safely and collision-free within designated transport roads, including people, fork-lift trucks and other vehicles.

The standard equipment of every robot MOBOT® AGV is a laser space scanner with configurable safety zones. For optimal robot operation, they have been limited to three ranges: the farthest zone in which the robot slows down, the warning zone, where it further slows down its movement and sending light and sound messages and the safe zone, in which the movement stops. The scanner is responsible for detecting obstacles that appear before the robot. Thanks to his action, the AGV robot can react accordingly by slowing down or stopping completely. This prevents possible collisions and ensures safe work with people. Already the most basic configuration allows the robot to work in direct contact with people.

Take, for example, the largest robot MOBOT® AGV FlatRunner MW. The example of braking distance on a concrete industrial floor, at maximum speed and a load of 1000 kg, is 465 mm. This is a very good result, especially compared to fork-lift trucks, where the vehicle's reaction time is still to be counted down to stop the vehicle's weight. In the case of AGV robots, a safety system is supervised over the reaction time, which initiates the robot's inhibition at the moment of detecting an obstacle within milliseconds, guaranteeing its absolute stop in a given zone.

It is worth paying attention to the housing robot - it is made of composites and has opaque shapes, without sharp, dangerous edges. But what if the load carried by the robot is heavy and has non-standard, large dimensions?

Many depend on the design of the adapter/carriage, which can be adapted to the details being transported. If the application requires it, such trucks can be equipped with additional sensors and security systems. Thus, if the transported detail extends significantly beyond the dimensions of the robot, the truck/adapter on which it is placed and attached to the robot may have, for example, an additional security scanner, safety switch or shield in a contrasting color.

The second, no less important issue is the space in which the robot will move. Together with the team responsible for logistics and security in a given company, we analyze route routes to select the shortest possible routes. This allows you to optimize the travel times and the traffic flow on the communication paths. It also guarantees 100% compliance with the rules prevailing in a given factory.
