Robotics scientists at Carnegie Mellon University in Pennsylvania set out to develop a device to automatically measure the caliper of nursery trees in the field, but found that a simple tree counter would be more useful for the tree fruit industry. Dr. Sanjiv Singh and colleagues began to develop the tree caliper calculator with shade tree nurseries in mind. The difference in value between large- and small-caliper trees can be significant. The device would be attached to a vehicle and would assess tree size as it moved down the nursery rows. The project is part of a major research project […]
