Magnetically Driven Quadruped Soft Robot with Multimodal Motion for Targeted Drug Delivery

Area of Science:

• Robotics
• Biomimicry
• Materials Science

Background:

• Untethered magnetic soft robots offer high flexibility for biomedical and micromanipulation tasks.
• Existing designs often mimic marine or reptilian locomotion, limiting adaptability in unstructured environments.

Purpose of the Study:

• To design and develop a novel quadruped magnetic soft robot.
• To enable adaptable locomotion in unstructured environments by integrating biomimetic principles and a unique actuation mechanism.

Main Methods:

• Designed a quadruped soft robot with a magnetic top cover and specific magnetization angle.
• Integrated principles of natural quadruped locomotion and a unique actuation method.
• Adjusted magnetic field parameters to control robot locomotion and environmental adaptation.

Main Results:
