Article Synopsis
- Certain aquatic insects use surfactants to move quickly on water, which has inspired research into self-propelling robots.
- This study presents a new method for liquid fuel delivery using a microfluidic pump that autonomously transports fuel to enable Marangoni propulsion.
- By analyzing different design parameters, researchers found ways to control the robot's movement distance, energy usage, and direction, potentially advancing the development of self-propulsion systems.
Drag-based swimming is usually accompanied with the shape change of rowing appendages to generate asymmetric force during the power stroke and recovery stroke. To implement this in an aquatic robot, one may actively control the surface area of its legs during the swimming. However, a small sized robot with a limited number of actuators should adjust the surface area of legs in passive manner.

Article Synopsis
- The article discusses the development of bio-inspired robots by studying animal locomotion, particularly focusing on aquatic arthropods.
- While there's considerable research on either animals or their robotic counterparts, there's a lack of comprehensive reviews that connect both fields.
- It highlights that despite existing studies, many aspects of aquatic locomotion in these animals remain under-explored, suggesting new research opportunities for creating more agile and efficient aquatic robots.
The locomotion of water beetles has been widely studied in biology owing to their remarkable swimming skills. Inspired by the oar-like legs of water beetles, designing a robot that swims under the principle of drag-powered propulsion can lead to highly agile mobility. But its motion can easily be discontinuous and jerky due to backward motions (i.
