A method for measuring the maturity of rock melons.

Various options for determining the maturity of rock melons by non-destructive means are discussed. A system is described for maturity determination which applies a relatively small force of varying magnitude through a domed probe, measures the resulting local deformation relative to a datum ring, and feeds the digitized information to a PC486 computer or micro-controller chip. From this data, the melon compliance curve is computed and compared with a predetermined compliance function threshold. In the context of robotic harvesting, the technique is intended to be used for maturity determination of individual melons in the field, providing a "pick" or "no pick" command to the harvesting robot. How this interrelates to the other operations involved in robotic harvesting is discussed. Application of the technique to grading operations in the packing house is also considered.
