A novel bionic jellyfish robot for seabed rock drilling and sampling exploration

Abstract

Sampling of seabed rock is an important technical measure for deep-sea resource exploration. Combining underwater bionic technology with ultrasonic drilling technology, a novel robot for submarine rock drilling and sampling is proposed in this paper. The robotic swimming system adopts a bionic jellyfish structure with flexible and stable movement, low noise, outstanding endurance and strong environmental adaptability. The anchoring and drilling device adopts ultrasonic energy to achieve stable adhesion on the seabed and reliable drilling efficiently under low penetrating force and low power consumption. The overall structure and drive control scheme of the robot are presented in this paper. Based on the principle of piezoelectric drive, the ultrasonic anchor and drill are designed. The design of submarine ultrasonic drilling and sampling robot is expected to accelerate the development of submarine exploration technology and promote the effective exploitation and utilization of deep-sea mineral resources.
