Design and analysis of extensible differential‐speed helical drive pipe dredging robot

open access: yesThe Journal of Engineering, Volume 2023, Issue 12, December 2023., 2023
The running state of the robot is simulated through virtual prototype technology. The results show that the robot has reasonable structure, comprehensive functions of cutting, stirring and transporting silt, so that the robot is basically in the ‘slurry flow’ condition in the sewer pipe.
