Model-Reference Adaptive Flight Control of a 95-mg Insect-Scale Flapping-Wing Aerial Robot
Francisco M. F. R. Gonçalves, Conor K. Trygstad, Néstor O. Pérez-Arancibia
Due to the system's scale and complex fabrication, the model describing the dynamics of a flapping-wing insect-scale aerial robot is subject to parameter uncertainty; for example,…
An Autonomous Subgram SMA-Based Swimmer
Conor K. Trygstad, Francisco M. F. R. Gonçalves, Néstor O. Pérez-Arancibia
We present the Swima, a bioinspired 900-mg swimmer propelled by two 10-mg high-work-density (HWD) actuators driven by shape-memory alloy (SMA) wires. We integrated onboard power an…
Force Characterization of Insect-Scale Aquatic Propulsion Based on Fluid-Structure Interaction
Conor K. Trygstad, Nestor O. Perez-Arancibia
We present force characterizations of two newly developed insect-scale propulsors--one single-tailed and one double-tailed--for microrobotic swimmers that leverage fluid-structure…
Feedback Control of a Single-Tail Bioinspired 59-mg Swimmer
Conor K. Trygstad, Cody R. Longwell, Francisco M. F. R. Gonçalves +2
We present an evolved steerable version of the single-tail Fish-&-Ribbon-Inspired Small Swimming Harmonic roBot (FRISSHBot), a 59-mg biologically inspired swimmer, which is driven…
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…
A New 1-mg Fast Unimorph SMA-Based Actuator for Microrobotics
Conor K. Trygstad, Xuan-Truc Nguyen, Nestor O. Perez-Arancibia
We present a new unimorph actuator for micro-robotics, which is driven by thin shape-memory alloy (SMA) wires. Using a passive-capillary-alignment technique and existing SMA-micros…
