The Panel Defense

The outstanding prize-winning "Integrated Rod-Structure Robot for Complex Pipelines" demonstrates great innovativity in driving wheels, enabling the bot to move freely in a highly complex inner-pipeline environment. The high adaptabilities and agility of this bot make it ideal as the conduit inspections and repair vehicles. This prize and innovation were also seen reported on the university Weibo.

Mr. Zhang Xuanhe and his team were awarded the third prize for the project "Sand Surface Modification and Emulsion Demulsification Application Based on Colloid Self-Assembly". In this project, the surface of the sandpile was carefully processed to be hydrophobic while leaving other parts untouched. This way succeeded in separating oil from water in the emulsion.
