Autonomous ground vehicles S5.2

Autonomous Unmanned Ground Vehicles

In 2019 SMP Robotics company started to ship the second generation of S series robots — Sхх.2. The new generation of autonomous mobile robots is a huge step in developing automation technologies for outdoor security and inspection tasks.

The next generation platform serves as a basis of S3.2, S5.2, S6.2, S7.2 robot models. Unlike the previous models, these robots are produced in series. They are currently being certified in accordance with the legal requirements that exist in the countries where our consumers are located.

These new models feature a significantly reworked construction. A mobile robot has a fully closed hardware section. This allowed us to achieve high levels of moisture and dust resistance and reduce electromagnetic emission. Besides, a double casing solution was implemented that helps to reduce direct sunlight-induced heating inside the robot. This solution improved thermal regimes of the electronic equipment and reduced the risk of overheating. The autonomous motion control system has undergone some exciting improvements.

Artificial intelligence for unmanned ground vehicles (UGVs)

The robots that feature an on-board analytics video system were equipped with a solution powered by NVidia Jetson TX2 supercomputer. This built-in computer makes it possible to process video using deep learning algorithms to perform tasks that require the use of artificial intelligence. The robot’s intelligent video surveillance system is compatible with all famous ONVIF CMS. Such as: Genetec, Milestone, Avigilon, Macroscop.

For the new robots, a range of important options was developed. The most notable option is the auto charging docking station. It allows a robot to charge its battery without any human intervention. The dock station has a wear-resistant mechanism and has successfully passed rigorous endurance tests.

The new robots equipped with sensitive front bumpers can be purchased together with a mesh fence detection feature. This optional feature helps to avoid incidents during the robot’s movement along a mesh fence and reduces the risk of damage caused by small-sized obstacles, such as thick wire or free-standing equipment and structures.

S series robots are powerful enough to move on gravel and concrete roads, however, they are not intended for use in off-road conditions as well as deep snow. The new A series is currently being developed — these robots will be suitable for snowy and off-road conditions, as well as rocky and sandy roads.

Autonomous Unmanned Ground Vehicle S series



SMP Robotics specializes in the development and serial production of several types of Autonomous Unmanned Ground Vehicles (UGVs), all of which are used as the basis for special-purpose mobile robots.

A mobile robot consists of two components: the UGV and the special-purpose equipment it carries.

UGVs of all series are equipped with an autonomous guidance system that allows the mobile robot to store its cruise route and move automatically without an operator.

The automatic guidance system operation is based on input from the video cameras, allowing the UGV to accurately follow programmable routes while detecting and avoid obstacles.

All UGVs produced by SMP Robotics have an electronic motor that drives and is powered by built-in accumulator batteries. When low on power, the UGV automatically returns to its maintenance area.

UGVs of different series vary in their mechanical powertrains, which are perfectly suited for different types of roads that our mobile robots may operate on.

Autonomous UGV S-series for landscaped areas and industrial facilities

This UGV series is designed for roads with good traction characteristics. These UGVs are ideal for landscaped area patrols and inspection of industrial facilities.

The guidance system uses visual navigation and is effective for pathfinding in environments densely filled with artificial structures and hard-surface paths. This Autonomous Unmanned Ground Vehicle can accurately complete routes of up to several kilometers long in areas with no GPS coverage. In case of insufficient lighting from street lamps at night, the UGV uses night markers located along the dark part of its cruise route.

A stereo camera is used for detecting obstacles and finding the optimal way. For the stereo camera to work correctly at night, the robot is equipped with a low beam headlamp, which switches on automatically at dusk.

The UGV S-series powertrain has two built-in accumulator batteries to power its autonomous movement systems. A third battery can be optionally installed for powering carried equipment. Standard size batteries are used, so you can choose those produced by a manufacturer that best suits your needs.

This wheeled robot is propelled by an electric rear transaxle with a differential that drives power efficiently while in motion. The front wheels are free-rolling and equipped with sensors for picking up data along the UGV’s route and for path-motion calculations.

Rear transaxle control is the best solution to ensure a good grip when moving along roads. The passage route should be laid so as to help the mobile robot avoid dirty areas in the rain, as hydroplaning could result. The UGV S-series can operate in hot climates. Special attention has been paid to the UGV’s cooling system, ensuring its operational capability at high temperatures.
