The XV-2 is a more capable and efficient robot than the XV-1 aimed to conduct operational tests within plant factories’ existing facilities.
Typical plant factories have vertically stacked racks for growing seedlings; XV-2 has a range of motion corresponding to the 2m tall plant factory racks used in factories. XV-2 also has many features for actual operation in plant factories. It includes autonomous driving using a magnetic guidance system, detection devices for racks lined up on both sides and automatic exchange of harvesting trays.
We have demonstrated that the XV-2 can perform pollination and harvesting operations under the same conditions as actual plant factories. In addition, the improved efficiency of the new robot has accelerated the ongoing verification experiments of pollination.
The XV-1 is the first robot developed to demonstrate robotic pollination: the XV-1 travelled on rails through a small facility simulating a plant factory, using a depth camera to recognise the position of fruit and flowers to test pollination and harvesting.
We collect the fruiting rate and deformity rate of fruits pollinated by the robot. In the experiments, XV-1 succeeded to pollinate with higher accuracy than bees or human hands.
