Researchers from INRoL (Interactive & Networked Robotics Laboratory) at Seoul National University have unveiled LASDRA, a dragon-like drone connected with multiple ODAR-8 links that are connected via cable with each other. By using its distributed rotors as “external actuation”, LASDRA can overcome the limitation of internal actuation and may one day lead to large dexterously-articulated robots.
This demonstration video showcases its design, modeling, joint locking strategy to increase its loading capability, and an innovative decentralized control scheme. The latter allows for compliant operation with scalability against the number of links. To validate their theory, the researchers also perform trajectory tracking and valve turning experiments.
