Dr Cheryl McCarthy is a Senior Research Fellow in mechatronic engineering with the Centre for Agricultural Engineering (formerly NCEA) at the University of Southern Queensland. Her research involves developing machine vision and sensing systems for agriculture. She has worked on machine vision projects for the beef, fodder and macadamia industries and her current projects include precision sensing of weeds for the sugar, cotton and grains industries. She has a BEng (Mechatronic) and PhD from USQ. Her research interests include the application of mechatronic engineering to agriculture and imaging spectrometry. She holds a CASA UAV Operator's Certificate.

Remote sensing of bait boxes to improve surveillance http://www.portbees.com.au/

The Australian honeybee industry is currently free from a number of exotic bee pests that have devastated honeybee populations around the world. This HIA/RIRDC project was to develop an electronic sensing system that could automatically detect when a swarm of bees had entered a bait box (an old beehive which is used as a pest bee trap), to save a bait box officer from having to continually check for exotic bees inside the bait box, and to allow round-the-clock trap monitoring.

Weed spot spraying for the cotton, sugar and pyrethrum industries

Weeds cost Australian agriculture $2-4 billion each year, with control methods typically comprising manual spot spraying, broadcast spraying or tillage operations. A Machine Vision System mounted on a tractor or ground robot can tell the difference between weeds and crop plants growing next to each other, and only spray the weed, hence reducing herbicide use.
