A lecturer within QUT’s Robotics and Autonomous Systems discipline, Dr Lehnert’s research interests lie in the development of novel methods for robotic manipulation in real-world and challenging environments, including autonomous robotic harvesters.
He has led an agricultural robotics team at QUT to develop one of the world’s best robotic capsicum harvesters, “Harvey”, which can autonomously detect and harvest sweet peppers within a real greenhouse. Harvey has been demonstrated to achieve a harvesting success rate of 76.5% in a real-world environment at 30 seconds per fruit. Harvey achieved this performance through a novel robotic vision system and patented robotic harvesting tool.
Most recently, Dr Lehnert developed a 3D-printed camera system, involving nine cameras operating at different depths, enabling a robot like Harvey to look around obstructing leaves much like a human.
