On–Off Switchable Micromotors for Use in Steerable Microvehicles
Advanced Robotics Research, EarlyView.Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion
Advanced Robotics Research, EarlyView.This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Optimizing Submerged Jet Flocculator Performance
, 1996 A 0.126-L/s (2-gpm) pilot plant was constructed to evaluate and optimize a novel water-jet mixing system for flocculation of suspended particles in water. The jet flocculator pilot plant consisted of a long vertical circular column with influent entering

Air bubble interaction with a submerged, axisymmetric water jet. [PDF]
The Journal of the Acoustical Society of America, 1991 Individual air bubbles were released from a vertical, blunt-tipped, 20-gauge hypodermic needle. They rose and collided with an axisymmetric, horizontal water jet submerged in a water-filled tank. Acoustic emissions resulting from bubble–jet interaction were studied. High-speed video analysis was also employed to visually determine bubble behavior (e.g.,

Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract
Advanced Robotics Research, EarlyView.We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a
