Aiming at several key problems, such as motion discontinuity, getting stuck and body
deformation, and appearing in the motion of wall-pressing pipeline robots (WPPRs) …

To move freely, in-pipe robots must be able to adapt to the various geometric changes of
pipes. Previously, we described an in-pipe robot that can adapt to changes in diameter and …

Pipe robots can perform inspection tasks to alleviate the damage caused by the pipe
problems. Usually, the pipe robots carry batteries or use a power cable draining power from …

The crawling conditions of variable pipeline robots were analyzed, and an adaptive
creeping device driven by a micro-hydraulic was proposed herein. First of all, the three-axis …

This study analyzes the throttling pressure control flow field, and the influencing factors of its
traction speed regulation and braking mechanism are determined. Throttling pressure …

In order to realize the precise positioning of the tools in the pipeline repair operation, solve
the problems of the traditional throttle speed control, such as slow response, long …

The in-pipe maintenance and repair technology based on the pipeline isolation plugging
robot (PIPR) is the primary means for ensuring the safety of subsea pipelines. Under the …

As the core of pipeline internal working condition detection system, the pipeline robot's
performance has become the biggest obstacle to the development of pipeline robots. This …

The structure of the in-pipe robot has a huge impact on its normal detection and dredging
inside the pipeline. The blockage inside the pipeline and the structure and size of the …

Complex pipelines exist in a variety of industrial equipment, such as aircraft engine. The
traditional examining and repairing method using borescope possibly brings additional …
