Robotic tech vest (RTV) is a special wearable equipment protecting workers near industrial robots. It is similar to a high-visibility jacket but for robots. Robots can sense a vest from a distance and avoid moving into it, thus protecting the wearer from collisions. [1]
The Occupational Safety and Health Administration (OSHA) has studied the topic of workers' safety in the areas of operating robots and concluded: "Studies indicate that many robot accidents occur during non-routine operating conditions, such as programming, maintenance, testing, setup, or adjustment. During many of these operations the worker may temporarily be within the robot's working envelope where unintended operations could result in injuries." [2] [3] Before employing RTVs, workers marked out the area where they would be working to enable the robotic route planner to smartly route around that area. [2]
In 2018, Amazon introduced robotic tech vests in 25 warehouses to protect workers from robot collisions. [4] This kind of equipment is needed in the warehouse, where human workers and robots cooperate. Additionally to the general obstacle detection of the robots, the RTV ensures that workers are detected as obstacles. It allows the robots to detect the human from farther away and update its trajectory. [5] A robotic tech vest is a combo of a belt and suspenders. [5] As according to Amazon in 2019, RTV has been introduced to more than 25 sites and more than 1 million activations were completed. [5] [1] The workers are safe with RTVs when they enter the area to fix a robotic system or retrieve fallen items. [1] Amazon claimed RTVs to be successful in 2019. [1]
The technology of robotic tech vest stands in contrast to the collaborative robots approach. [5] In case of collaborative robots, the RTVs are not needed.
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. Protective clothing is applied to traditional categories of clothing, and protective gear applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit.
High-visibility clothing, sometimes shortened to hi vis or hi viz, is any clothing worn that is highly luminescent in its natural matt property or a color that is easily discernible from any background. It is most commonly worn on the torso and arm area of the body. Health and safety regulations often require the use of high visibility clothing as it is a form of personal protective equipment. Many colors of high visibility vests are available, with yellow and orange being the most common examples. Colors other than yellow or orange may not provide adequate luminescence for conformity to standards such as ISO 20471.
A forklift is a powered industrial truck used to lift and move materials over short distances. The forklift was developed in the early 20th century by various companies, including Clark, which made transmissions, and Yale & Towne Manufacturing, which made hoists.
Construction site safety is an aspect of construction-related activities concerned with protecting construction site workers and others from death, injury, disease or other health-related risks. Construction is an often hazardous, predominantly land-based activity where site workers may be exposed to various risks, some of which remain unrecognized. Site risks can include working at height, moving machinery and materials, power tools and electrical equipment, hazardous substances, plus the effects of excessive noise, dust and vibration. The leading causes of construction site fatalities are falls, electrocutions, crush injuries, and caught-between injuries.
A construction worker is a person employed in the physical construction of the built environment and its infrastructure.
Obstacle avoidance, in robotics, is a critical aspect of autonomous navigation and control systems. It is the capability of a robot or an autonomous system/machine to detect and circumvent obstacles in its path to reach a predefined destination. This technology plays a pivotal role in various fields, including industrial automation, self-driving cars, drones, and even space exploration. Obstacle avoidance enables robots to operate safely and efficiently in dynamic and complex environments, reducing the risk of collisions and damage.
North American Occupational Safety and Health (NAOSH) Week is an annual celebration that happens during the first full week of May. The aim of the event is to raise awareness about occupational safety, health, and the environment (OSH&E) in order to avoid workplace injuries and illnesses.
The third driverless car competition of the DARPA Grand Challenge was commonly known as the DARPA Urban Challenge. It took place on November 3, 2007 at the site of the now-closed George Air Force Base, in Victorville, California, in the West of the United States. Discovery's Science channel followed a few of the teams and covered the Urban Challenge in its RobocarsArchived 2008-07-30 at the Wayback Machine series.
A collision avoidance system (CAS), also known as a pre-crash system, forward collision warning system (FCW), or collision mitigation system, is an advanced driver-assistance system designed to prevent or reduce the severity of a collision. In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles, so that it can provide a warning to the driver if the vehicles get too close, potentially helping to avoid a crash. Various technologies and sensors that are used include radar (all-weather) and sometimes laser (LIDAR) and cameras to detect an imminent crash. GPS sensors can detect fixed dangers such as approaching stop signs through a location database. Pedestrian detection can also be a feature of these types of systems.
Amazon Robotics LLC, formerly Kiva Systems, is a Massachusetts-based company that manufactures mobile robotic fulfillment systems. It is a subsidiary of Amazon.com. Its automated storage and retrieval systems have been used in the past by companies including The Gap, Walgreens, Staples, Gilt Groupe, Office Depot, Crate & Barrel, Amazon and Saks 5th Avenue. Employees of Erstwhile Kiva now only work in Amazon warehouses.
Inhalation is a major route of exposure that occurs when an individual breathes in polluted air which enters the respiratory tract. Identification of the pollutant uptake by the respiratory system can determine how the resulting exposure contributes to the dose. In this way, the mechanism of pollutant uptake by the respiratory system can be used to predict potential health impacts within the human population.
A powered exoskeleton is a mobile machine wearable over all or part of the human body, providing ergonomic structural support, and powered by a system of electric motors, pneumatics, levers, hydraulics or a combination of cybernetic technologies, allowing for sufficient limb movement, and providing increased strength, protection and endurance.
A cobot, or collaborative robot, also known as a companion robot, is a robot intended for direct human-robot interaction within a shared space, or where humans and robots are in close proximity. Cobot applications contrast with traditional industrial robot applications in which robots are isolated from human contact or the humans are protected by robotic tech vests. Cobot safety may rely on lightweight construction materials, rounded edges, and inherent limitation of speed and force, or on sensors and software that ensure safe behavior.
Occupational safety and health (OSH) or occupational health and safety (OHS) is a multidisciplinary field concerned with the safety, health, and welfare of people at work. OSH is related to the fields of occupational medicine and occupational hygiene and aligns with workplace health promotion initiatives. OSH also protects all the general public who may be affected by the occupational environment.
Engineering controls are strategies designed to protect workers from hazardous conditions by placing a barrier between the worker and the hazard or by removing a hazardous substance through air ventilation. Engineering controls involve a physical change to the workplace itself, rather than relying on workers' behavior or requiring workers to wear protective clothing.
Workplace robotics safety is an aspect of occupational safety and health when robots are used in the workplace. This includes traditional industrial robots as well as emerging technologies such as drone aircraft and wearable robotic exoskeletons. Types of accidents include collisions, crushing, and injuries from mechanical parts. Hazard controls include physical barriers, good work practices, and proper maintenance.

Hazard controls for COVID-19 in workplaces are the application of occupational safety and health methodologies for hazard controls to the prevention of COVID-19. Multiple layers of controls are recommended, including measures such as remote work and flextime, personal protective equipment (PPE) and face coverings, social distancing, and enhanced cleaning programs. Recently, engineering controls have been emphasized, particularly stressing the importance of HVAC systems meeting a minimum of 5 air changes per hour with ventilation or MERV-13 filters, as well as the installation of UVGI systems in public areas.
The impact of artificial intelligence on workers includes both applications to improve worker safety and health, and potential hazards that must be controlled.
