UVD Robots, a subsidiary of Blue Ocean Robotics, are able to disinfect patient rooms and operating theaters in hospitals. The robots consist of a mobile base equipped with multiple lidar sensors and an array of powerful short wavelength ultraviolet-C (UVC) lights.

The operators deploy the robot using a computer. The robot scans the environment using its lidars and creates a digital map. The operator can then annotate the map indicating all the rooms and points the robot should not disinfect. After that, the robot relies on simultaneous localization and mapping (SLAM) to navigate.

然后，机器人自主地驱动医院，同时每秒每平方米（1米距离）为254纳米光的20焦耳，以消除细菌和其他有害的微生物。因此，医院可以保证99.99％的消毒率 - 降低患者，员工和收缩危险感染的亲属的风险。

In May 2020, Frost & Sullivan awarded Blue Ocean Robotics the Best Practice Award for „2020 European Professional Service Robots Product Leadership“ for their virus-killing UVD robots. In 2019, the company received an Innovation and Entrepreneurship Award in Robotics and Automation (IERA).

San Antonio-based Xenex Disinfection Services LLC makes full-spectrum UV Germ-Zapping Robots to eliminate harmful bacteria, viruses and spores that can cause healthcare-associated infections (HAIs).

与大多数单谱低强度紫外线(污染物) devices, Xenex’ LightStrike uses a xenon lamp to generate bursts of high intensity, full germicidal spectrum (200-315 nanometers) UVC light that is more intense than sunlight. According to the company, its robot is the only pulsed xenon UV device of its kind, while other companies manufacture mercury UV devices.

在近三十名不同的同行评审期刊上发表的研究表明，在医院获得的53％〜100％的疗养中的减少。在最近的测试中，在德克萨斯州生物医学研究所进行，闪电机器人在两分钟内摧毁了SARS-COV-2，在此时的四个日志（99.99％）减少了。

Shanghai’s TMI Robotics has developed a robot that moves completely autonomously, fulfilling the task as pre-programmed with the layout and topography of the hospital or department. It will set off systematically disinfecting nearby air and all surfaces in any given area, and even return itself to a docking station when it requires a recharge.

The robot integrates three disinfection modes: ultraviolet, ultra-dry vaporized hydrogen peroxide, and air filtration to meet the demanding disinfection requirements in the healthcare sector. UV alone, at the optimal distance, can achieve 99.99 percent bacterial kill - including antibiotic-resistant bacteria and viruses. When combined with air-filtration, it forms a highly effective method of disinfecting and cleansing the surrounding air, in addition to achieving surface disinfection of surrounding walls, furniture and fixings.

Any combination of these methods can be applied depending on the space or departmental rooms to be disinfected. The robot also automatically calculates the disinfection time according to the space and fixings and ensures no ‘dead spots’.

XDBOT

Researchers from Nanyang Technological University, Singapore (NTU Singapore), have developed a semi-autonomous robot that can disinfect large surfaces quickly. XDBOT, or ‘eXtreme Disinfection roBOT’, can be wirelessly controlled via a laptop or tablet. That removes the need for cleaners to be in contact with surfaces, thereby reducing the risk of picking up the virus from potentially contaminated areas.

XDBOT can navigate semi-autonomously in any environment using LIDAR (Light Detection and Ranging) and high-definition cameras, while its arm is controlled by a human operator – like a tank with a rotating turret. Currently, the operator can control the robot from up to 30 meters using a laptop/tablet, which can be increased to 50 meters or further with more antennas installed on XDBOT.

它不是传统的压力喷嘴，它使用静电带喷嘴，以确保消毒剂，后面和隐藏表面的宽和进一步扩散。与典型的喷嘴不同，XDBOT的喷嘴用正电荷排出化学品。然后将这些消毒剂吸引到所有带负电的表面。已经覆盖的消毒剂已经覆盖的表面将击退喷雾，使该方法非常有效。这种费用吸引力的概念类似于磁体的正极和负极彼此如何。

Tru-D SmartUVC

Memphis-based Tru-D SmartUVC (Total Room Ultraviolet Disinfection) robot stands 5-feet-6-inches tall and uses ultraviolet germicidal irradiation (UV) to disinfect porous and non-porous surfaces without toxic chemicals. Its automated, remote-controlled mobile disinfection system uses UV light that is capable to kill up to 99.9 percent of harmful pathogens. The high energy from UV light is absorbed in the cellular RNA and DNA of microorganisms, damaging nucleic acids and preventing them from reproducing; therefore, they cannot survive or infect humans.

其传感器360允许系统自动计算每个房间所需的病原体致致死剂量，并动态补偿尺寸，形状和其他剂量变化的变量，例如内容物，窗口，百叶窗和门的位置。

During the disinfection cycle, Tru-D’s microprocessors and instrument-grade sensors measure the necessary amount of UVC energy that is reflected back to the robot to destroy pathogens throughout an entire room from one position.
In November 2019, PDI acquired majority share of Tru-D SmartUVC.

The robot has two working modes:

For the first mode, air circulating sterilization and disinfection, the robot is equipped with high-power UV lamps. Air flows into the UV sterilization channel through the purification and circulation system. The robot is capable of killing microorganisms in the air, such as fungi, bacteria, and viruses, and has significant effects on harmful microorganisms in aerosols and the like. At the same time, PM2.5, formaldehyde, TOVC and other harmful substances in the air can be eliminated due to HEPA filtration.

第二模式,紫外线杀菌和disinfection, the robot is turned on in an unmanned state through infrared induction, and the sterilization and disinfection center will emit the condensed UV beams to kill bacteria and other harmful microorganisms, which prevents cross infection in high-risk areas and purifies the air.

In addition, the robot features autonomous operation and realizes timed, fixed-point and multi-track mobile disinfection and sterilization in a large space, according to the preset route and time requirements. It reduces the investment in human resources and helps promote the working efficiency and quality.

Engineers at Siemens and Aucma Co. Ltd have developed an intelligent disinfection robot to battle against the coronavirus and other viruses in hospitals. Most disinfection robots combine a petrol-driven moisturizer gun with an electric chassis. However, on-site refueling of robots is neither clean nor convenient. The team therefore decided to develop purely electric disinfection robots to better cater to the needs of hospitals. Powered by a lithium battery, the robot can disinfect up to 36,000 square meters in one hour.

To make the robots operate easily on various road surfaces, the team adopted a caterpillar chassis instead of wheels to improve their ability to surmount obstacles surmounting and climb slopes. A 360-degree camera platform on the top transmits videos and information in real time, coupled with an intelligent vision algorithm that allows the operator to remotely locate affected areas and prevent the spread of infectious diseases at low cost.

Violet can greatly reduce dependency on the use of chemical-based solutions, which may be effective but require rooms to be vacated for several hours during sterilization, making them impractical for many parts of the hospital. In addition, many pieces of high-tech equipment cannot be disinfected using “deep chemicals”, so manual cleaning is needed.
