The need of improving the quality of professions led to the idea of simplification of processes during chimney sweeping. These processes have been essentially the same for tens of years. The goal of this paper is to bring an automation element into the chimney sweeping process, making the job easier for the chimney sweeper. In this paper, an essentially in-pipe robot is presented, which uses brushes to move while simultaneously cleaning the chimney or pipeline. The problem of the robot motion was reduced using an in-pipe robot due to the environments and obstacles that the robot has to face. An approach of using a pneumatic actuator for motion is presented along with the mechanical design. The next part of this paper is focused on the mathematical model of the robot motion, as well as its simulation and testing in the experimental pipeline. The simulations were compared with the experimental measurements and a few analyses were conducted describing the simulation model and its differences with the real robot, as well as considering certain parameters and their impact on the performance of the robot. The results are discussed at the end of the paper.

To repair leaking pipelines for oil, natural gas and other dangerous media, a kind of pipeline sealing robot is proposed. The device is mainly divided into a robot drive unit, connection unit, and blocking unit. The robot drive unit is used to pull the blocking unit, allowing it to move in the pipeline. The connection unit is used to connect the robot drive unit and the blocking unit. The blocking unit is used to complete the repair at the leakage point. When the robot operates, the drive unit drags the blocking device to the pipeline leakage location, and the front camera can detect the size and shape of the leakage hole. The sealing unit is located at the leakage point, an airbag is inflated, and the adhesive in it is used to seal and repair the leak. Two performance indices (climbing performance and curve passing performance) are evaluated when the robot drive unit is walking. A 3D model of the robot is established, and the performance index of the robot is simulated and analyzed using virtual prototype technology. An experimental platform is built for verification. The conclusions are as follows: (1) A spring with a 13 N/mm rigidity yielded the best performance, and the robot could crawl up a 37° slope. (2) When the deflection angle of the driving wheel was set to 30°, the robot could smoothly pass a bend with a radius of curvature of 500 mm. Thus, the robot performance met the design requirements.

“…Figure 1 illustrates an example of operator-control related hazards, which includes overheating of hardware parts of the robot, due to suboptimal control of speed and orientation of the robot by the operator. This is usually via interacting with the monitoring pendant (an example shown in Figure 1) while controlling the agent to navigate the confined pipeline, which may contain hazardous substances (Li et al, 2020).…”

Redefining Safety in Light of Human-Robot Interaction: A Critical Review of Current Standards and Regulations

Policymakers need to consider the impacts that robots and artificial intelligence (AI) technologies have on humans beyond physical safety. Traditionally, the definition of safety has been interpreted to exclusively apply to risks that have a physical impact on persons’ safety, such as, among others, mechanical or chemical risks. However, the current understanding is that the integration of AI in cyber-physical systems such as robots, thus increasing interconnectivity with several devices and cloud services, and influencing the growing human-robot interaction challenges how safety is currently conceptualised rather narrowly. Thus, to address safety comprehensively, AI demands a broader understanding of safety, extending beyond physical interaction, but covering aspects such as cybersecurity, and mental health. Moreover, the expanding use of machine learning techniques will more frequently demand evolving safety mechanisms to safeguard the substantial modifications taking place over time as robots embed more AI features. In this sense, our contribution brings forward the different dimensions of the concept of safety, including interaction (physical and social), psychosocial, cybersecurity, temporal, and societal. These dimensions aim to help policy and standard makers redefine the concept of safety in light of robots and AI’s increasing capabilities, including human-robot interactions, cybersecurity, and machine learning.
