Dancing Honey bee Robot Elicits Dance-Following and Recruits Foragers

TL;DR

This study demonstrates that a biomimetic honeybee robot can successfully mimic natural dance patterns, elicit dance-following behavior in live bees, and influence their flight paths, advancing understanding of insect communication.

Contribution

The paper introduces RoboBee, a robotic honeybee capable of reproducing waggle dance cues and recruiting live bees, providing new insights into bee communication mechanisms.

Findings

Robotic dance elicits natural dance-following in bees.

Bees adjust flight paths based on robotic dance cues.

First successful use of a biomimetic robot for bee recruitment.

Abstract

The honey bee dance communication system is one of the most popular examples of animal communication. Forager bees communicate the flight vector towards food, water, or resin sources to nestmates by performing a stereotypical motion pattern on the comb surface in the darkness of the hive. Bees that actively follow the circles of the dancer, so called dance-followers, may decode the message and fly according to the indicated vector that refers to the sun compass and their visual odometer. We investigated the dance communication system with a honeybee robot that reproduced the waggle dance pattern for a flight vector chosen by the experimenter. The dancing robot, called RoboBee, generated multiple cues contained in the biological dance pattern and elicited natural dance-following behavior in live bees. By tracking the flight trajectory of departing bees after following the dancing robot via harmonic radar we confirmed that bees used information obtained from the robotic dance to adjust their flight path. This is the first report on successful dance following and subsequent flight performance of bees recruited by a biomimetic robot.
