Miniature Multihole Airflow Sensor for Lightweight Aircraft Over Wide Speed and Angular Range

ICRA 2026poster

An aircraft's airspeed, angle of attack, and angle of side slip are crucial to its safety, especially when flying close to the stall regime. Various solutions exist, including pitot tubes, angular vanes, and multihole pressure probes. However, current sensors are either too heavy (>30 g) or require …

SailMAV: Water-Surface Locomotion and Biodiversity Monitoring (I)

ICRA 2026poster

Existing aquatic robotic vehicles tend to be large, heavy, and difficult to deploy. This often renders them unsuitable for monitoring delicate aquatic habitats and hard-to-access areas. We present a comprehensive framework for the design and development of sailing micro aerial vehicles (SailMAVs), w…

Design of the High-Payload Flapping Wing Robot E-Flap

RA-L 2021

Autonomous lightweight flapping-wing robots show potential to become a safe and affordable solution for rapidly deploying robots around humans and in complex environments. The absence of propellers makes such vehicles more resistant to physical contact, permitting flight in cluttered environments, a

MEDUSA: A Multi-Environment Dual-Robot for Underwater Sample Acquisition

RA-L 2020

Aerial-aquatic robots possess the unique ability of operating in both air and water. However, this capability comes with tremendous challenges, such as communication incompatibility, increased airborne mass, potentially inefficient operation in each of the environments and manufacturing difficulties

Unmanned Aerial Sensor Placement for Cluttered Environments

RA-L 2020

Unmanned aerial vehicles (UAVs) have been shown to be useful for the installation of wireless sensor networks (WSNs). More notably, the accurate placement of sensor nodes using UAVs, opens opportunities for many industrial and scientific uses, in particular, in hazardous environments or inaccessible

SailMAV: Design and Implementation of a Novel Multi-Modal Flying Sailing Robot

RA-L 2019

Despite significant research progress on small-scale aerial–aquatic robots, most existing prototypes are still constrained by short operation times and limited performance in different fluids. The main challenge is to design a vehicle that satisfies the partially conflicting design requirements for

Power and Control Autonomy for High-Speed Locomotion With an Insect-Scale Legged Robot

RA-L 2018

We present a power and control autonomous, insect-scale legged robot the Harvard Ambulatory MicroRobot with RF communication (HAMR-F). At only 2.8 g and 4.5 cm in length, HAMR-F is capable of locomotion at speeds up to 17.2 cm/s (3.8 body lengths per second) with an onboard battery. Two microcontrol
