Fun With ‘Robo-Bugs’
One robot that can retrieve objects drifting into deep water using a whirligig beetle’s swimming ability. Another that can deliver letters and greeting cards with the speed and grace of a dragonfly. Both were among the “Robo-Bugs” imagined and designed by third graders at Barclay Elementary/Middle School last fall.
