a general robotic mechanism was presented for in-pipe inspection oflevel pipes with varied diameter or curved pipelines. the robot employed three legs comprised of parallelogram linkages mechanism which enables adapting to various elbow joints in the piping systems. the curvatures in pipeline are the most important constraints in front of the robot through navigation process. to study the adapt...

the suspension system of a vehicle is one of the most important parts which is involved in the process of vehicle designing. when a vehicle suspension system is designed, the evaluation of its performance against the road disturbances such as shocks and bumps are very important. the most commonly used systems consist of four hydraulic jacks with mobility in vertical line with low speed and low ...

In-pipe robots, which have a long history of development in robotics, can be.This paper describes a mobile feeder pipe inspection robot that can minimize the irradiation dose to human workers by automating the measurement process.Recently, many pipe inspection robot systems have been developed. Initially, development ...

Pipe inspection is one of the areas that have attracted high research interest for robot applications especially in oil and chemical industry and civil engineering. Robot body rolling while it travels within a pipe has been a problem for accurately collecting inspection data. Under certain circumstances where vision systems have to be employed, robot body rolling may cause vision inspection dat...

Concentrated solar power (CSP) plants are expansive facilities that require substantial inspection and maintenance. A fully automated inspection robot increases the efficiency of maintenance work, reduces operating and maintenance costs, and improves safety and work conditions for service technicians. This paper describes a climbing robot that is capable of performing inspection and maintenance...

The ultrasonic wave is applied as an inspection method for the gas-holder and the pipeline in service. In such an inspection, the application of an automatic inspection system is desirable, because a manual inspection is difficult to accomplish perfectly and exactly due to its enormity, a so-called nondestructive inspection robot is then preferable. However, an ultrasonic nondestructive inspect...
