What is Grafting robots?

The first commercial model of a grafting robot (GR800 series, Iseki & Co. Ltd., Matsuyama, Japan) became available for cucurbits back in 1993. Since then, semi- or fully-automated grafting robots were invented by several agricultural machine industries and several commercial models are available in East Asia, Europe, and more recently in the U.S. Semi-automated grafting robots generally graft at a speed of 600-800 grafts per hour (speed equivalent of 5-6 skilled workers for cucurbit, and 2-3 skilled workers for tomato), but require a minimum of two workers and one trained worker to inspect the grafting quality.
