Multi-modal jumping and crawling in an autonomous, springtail-inspired microrobot

ICRA 2024poster

Springtails are tiny arthropods that crawl and jump. They jump by temporarily storing elastic energy in resilin elastic cuticular structures and releasing that energy to accelerate a tail, called a furca, propelling them in the air. This paper presents an autonomous, springtail-inspired microrobot t…

3D Printed Ferrofluid Based Soft Actuators

ICRA 2019poster

This work demonstrates 3D printed soft actuators with complex shapes and remote actuation using an external magnetic field. Instead of embedding magnetic particles in a polymeric matrix, we fabricated a novel ferrofluid-based actuator, in which the fluid can be moved to different locations in the ac…

A Lightweight, Compliant, Contact-Resistance-Based Airflow Sensor for Quadcopter Ground Effect Sensing

ICRA 2018poster

Sensors to measure quadcopter ground effect are often relatively large, heavy, and require significant power, which restricts their applicability when it comes to small quadcopters and other aircraft that require lightweight and non-obstructive solutions. This paper presents the design of an elastom…

3DFlex: A rapid prototyping approach for multi-material compliant mechanisms in millirobots

ICRA 2017poster

This paper describes an intuitive method for the design and fabrication of small-scale robots with multi-material compliant mechanisms in 3D. The rigid components are 3D printed, and flexures are inserted into the rigid components, creating the final mechanism. The assembled mechanisms are robust, r…
