Harnessing Ultrafast Optical Pulses for 3D Microfabrication by Selective Tweezing and Immobilization of Colloidal Particles in an Integrated System

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

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.

Development of Harmonic Reducing Transmission for Legged Robots

2021 18th International Conference on Ubiquitous Robots (UR), 2021
Transmission mechanisms such as belts and link-ages are adopted in quadruped robots for small inertia. In addition, to obtain the high torque required for legged robots, the electric motor adopts a reduction mechanism, such as a harmonic reducer or a planetary reducer.

Harmonic reducer converter

IEEE Transactions on Industrial Electronics, 2002
A new strategy to accomplish low frequency regulation IEC 1000-3-2 at system level is proposed in this paper. By means of a simple power converter, connected in parallel with the loads, the harmonic currents generated by them are greatly reduced, being unnecessary to change the loads.
