Power-Efficient Actuation for Insect-Scale Autonomous Underwater Vehicles
Cody R. Longwell, Conor K. Trygstad, Nestor O. Perez-Arancibia
We present a new evolution of the Very Little Eel-Inspired roBot, the VLEIBot++, a 900-mg swimmer driven by two 10-mg bare high-work density (HWD) actuators, whose functionality is…
A New 10-mg SMA-Based Fast Bimorph Actuator for Microrobotics
Conor K. Trygstad, Elijah K. Blankenship, Nestor O. Perez-Arancibia
We present a new millimeter-scale bimorph actuator for microrobotic applications, driven by feedforward controlled shape-memory alloy (SMA) wires. The device weighs 10 mg, measures…
Progress Towards Submersible Microrobots: A Novel 13-mg Low-Power SMA-Based Actuator for Underwater Propulsion
Cody R. Longwell, Conor K. Trygstad, Francisco M. F. R. Goncalves +2
We introduce a new low-power 13-mg microactuator driven by shape-memory alloy (SMA) wires for underwater operation. The development of this device was motivated by the recent creat…
VLEIBot: A New 45-mg Swimming Microrobot Driven by a Bioinspired Anguilliform Propulsor
Elijah K. Blankenship, Conor K. Trygstad, Francisco M. F. R. Gonçalves +1
This paper presents the VLEIBot^* (Very Little Eel-Inspired roBot), a 45-mg/23-mm^3 microrobotic swimmer that is propelled by a bioinspired anguilliform propulsor. The propulsor is…
