Basic studies on robot to work in vineyard (Part 3). Measurement of physical properties for robotization and manufacture of berry thinning hand

, : Basic studies on robot to work in vineyard (Part 3). Measurement of physical properties for robotization and manufacture of berry thinning hand. Journal of the Japanese Society of Agricultural Machinery 56(2): 93-100

The automation of grape thinning operations was investigated in order to develop a grape production system. The physical properties of grapes were measured and a thinning hand was constructed.
