Core Concepts
Introducing BatDeck for nano-drone obstacle avoidance using ultrasonic sensors.
Abstract
Nano-drones are ideal for confined spaces.
BatDeck employs ultrasonic sensors inspired by bats.
Sensor characteristics and experimental results are discussed.
Ultrasonic sensors offer effective obstacle avoidance on nano-drones.
Comparison with laser-based ToF sensors is provided.
Implementation of an OA algorithm tailored for resource-constrained hardware.
In-field evaluation shows the effectiveness of BatDeck in challenging environments.
Stats
Results show that BatDeck allows exploration for a flight time of 8 minutes while covering 136m on average before a crash in a challenging environment with transparent and reflective obstacles.
Quotes
"Nano-drones, distinguished by their agility, minimal weight, and cost-effectiveness, are particularly well-suited for exploration in confined, cluttered and narrow spaces."
"Inspired by bats, which can fly at high speeds in complete darkness with the help of ultrasound, this paper introduces BatDeck."
