This research was to develop and preliminary test the mangosteen harvesting equipment (MHE). The principle of the equipment is similar to holding and twisting the fruit from the stem. The electronic color and force sensors were attached to the equipment in order to check the maturity stage of mangosteen (MT) and to protect the damage of MT during harvesting respectively. The methodology consisted of 1) testing of the electronic color and force sensors in laboratory with tennis ball and 2) preliminary testing of the MHE in the orchard. The results showed that 1) the MHE can be operated both manually which inspecting the maturity stage and harvesting by the operator or semi-automatic which inspecting maturity stage by electronic color sensor. When the inspected fruit was detected as the calibrated color, the equipment will hold and twist the fruit from the stem, The two installed electronic sensors can work together effectively and 2) the capacity of MHE was 180 and 210 fruits/hr. for semi-automatic and manual operating system respectively. The results showed that there was no damage on MT harvested by the equipment. However, there are some limiting factors that need further development.
