Der Spiegel's international desk has a interesting feature on attempts in the Rheingau and surrounding regions to preserve traditional viniculture with robotic aid. Engineers at the University of Geisenheim have developed a rover-prototype that can scale the steep hills at times approaching a right-angle.
For decades, many vintners have chosen to retire their harvest to flat land as the geometry of steeper slopes has proven unprofitable and presents a risk to life and limb. Hillsides are preferable because the grapes here tend to be exposed to more sun and enjoy better drainage, thus preventing rot on the vine. Along the Rhein, however, I know that there are growers who perennially open up grape picking to volunteers of the public and feast them after a hard day's work. With some modification to the rows of vines yet minimal supervision, the robots can accomplish routine tasks like watering and pruning and have even produced their own vintage, taste-tested by vineyards in doubt. Reception is positive and apparently the units are on pre-order, but there's no word if they will be assigned additional duties.
