The RT-G police robot in China
Advanced technology in police service
The introduction of spherical police robots in China, known as "RT-G," marks a significant step in the increasing integration of artificial intelligence (AI) and robotics into security-related areas. These rounded machines, developed by the Chinese robotics company Logon Technology, represent, according to Chinese authorities, a major milestone in modern law enforcement. Their deployment is intended to increase police efficiency, minimize threats, and ultimately enhance public safety. High expectations are placed on this technological innovation, while at the same time sparking controversial discussions about ethical and legal issues.
Specifications and mobility of the RT-G robots
“This new generation of police robots is designed to help us respond to threats more quickly and identify criminals more effectively,” said a spokesperson for the Chinese police, highlighting the advantages of the RT-G models. The robots have a diameter of approximately 60 centimeters and weigh about 125 kilograms. Their distinctive, spherical shape clearly sets them apart from other robotic systems previously used in security. With the aid of a central wheel that is barely visible from the outside, the RT-G moves with exceptional agility through urban landscapes and can even operate on challenging terrain. “Our developers placed great emphasis on robustness, mobility, and versatility,” explained an engineer from Logon Technology. “The RT-G must be able to remain operational on both paved roads and muddy surfaces, and it must be able to safely avoid obstacles.”
Suitable for use in aquatic environments
Particularly impressive is the RT-G robot's ability to move not only on land but also in water. The developers have integrated a system that allows them to propel themselves through liquid environments like a paddle steamer. They can float on the surface and are thus able to monitor rivers, canals, or artificial waterways in cities. This is intended to prevent criminals from escaping by water or hiding contraband there. "The RT-G is designed to cover as many operational scenarios as possible," says one of the project's lead engineers.
AI-powered monitoring functions
Of particular interest are the advanced AI-based capabilities of the RT-G. Using sensitive sensors, high-resolution cameras, and specialized software, the robot can detect unusual activities, conspicuous behavior patterns, or suspicious objects. It utilizes complex algorithms that allow it to compare faces with existing police databases to identify wanted individuals. For example, the RT-G can recognize potential criminals in the vicinity and alert the relevant authorities. "Thanks to integrated facial recognition, we are now able to identify individuals in public spaces much more quickly," explains a police spokesperson. "This not only speeds up investigations but can also help reduce false accusations."

Non-lethal weapons as equipment
Another aspect that makes the RT-G robots interesting from the authorities' perspective is their equipment with non-lethal weapons. These include net launchers, which allow suspects to be captured without seriously injuring them, as well as tear gas launchers and sonic dispersal devices. The latter can use targeted, loud sound pulses to induce groups of people to disperse without causing lasting harm. "We want to increase public safety without using unnecessary force," emphasizes a representative of the police leadership. "The RT-G is not a device that simply fires indiscriminately. Rather, it is intended to support, de-escalate, and assist until human officers arrive on the scene."
Practical test runs and integration into everyday police work
Current trials are taking place in selected Chinese cities to determine how this technology integrates into real-world policing. Particularly in densely populated urban areas, the robot can help monitor public squares, parks, pedestrian zones, waterfronts, and traffic intersections. The goal is not to replace human police officers, but to facilitate their work, defuse dangerous situations, and ensure faster response times. "We see the RT-G as a complement to our existing measures, not as competition for our police forces," explains a senior police officer. "Its deployment allows us to allocate resources more effectively and monitor critical points in real time."
Critical voices and ethical concerns
However, questions remain, and public opinion is divided. While proponents see increased security as a positive, critics express concerns regarding data protection, privacy, and potentially excessive surveillance. "We mustn't forget that behind every technological advancement lies the risk of misuse," says a Chinese lawyer specializing in data protection law. "Society must ask itself how far we want to go when it comes to expanding camera presence and facial recognition in public spaces." The fear is often voiced that, once established, such technologies could also be used for politically motivated surveillance or to suppress dissenting opinions.
International Perspectives: A Global Trend
Nevertheless, China is not alone in following this trend; other countries are doing so as well. In some Asian countries, in the Middle East, and also in Western metropolises, police authorities are already experimenting with robot-assisted surveillance systems. "This development shows that the use of AI and robotics in law enforcement is a global phenomenon," says an international security expert. "Whether it's the RT-G in China, patrol robots in Singapore, or robot dogs in the United States—we are moving toward an era in which technological systems will play a completely new role in security and public order."
Future prospects and potential risks
The RT-G robots in China are laying the foundation for a future scenario in which human-machine interaction in law enforcement is completely redefined. It's conceivable that future generations of these robots will operate even more autonomously, access even more data, and make more complex decisions. "One goal is for the RT-G not only to observe, but also to analyze behavioral patterns in the long term, recognize potential dangers in advance, and initiate preventative measures," emphasizes a Chinese AI researcher. This could mean that such robots will not only react to past wrongdoing, but also prevent criminal acts from occurring in the first place.
The future of policing will also be shaped by robots and AI systems
The introduction of RT-G vividly demonstrates that law enforcement is undergoing a comprehensive transformation. Traditional policing, which for decades was primarily characterized by human presence and reactive action, is now being equipped with these new technologies as a tool intended to make information gathering, crime prevention, and surveillance more efficient. This opens up new avenues that offer opportunities but also create significant potential for abuse.
In any case, China has sent a clear signal with RT-G: the future of policing will increasingly be shaped by robots and AI systems. Whether this ultimately leads to a fairer, more transparent, and safer society will depend on how these technologies are developed, regulated, and deployed in the coming years.
