1. Product Overview
EA2021 Series full-scope perception intelligent plant protection UAV is an
intelligent multi-rotor plant protection UAV released by Suzhou Eavision Robotic
Technologies Co., Ltd. Based on the industry-leading stereovision technology, the UAV
can complete plant protection services of various fields crops and cash crops. It has
the following functions:
Intelligent Terrain-following: It can complete plant protection services in plains,
hills, mountains, wetlands or other complex terrains;
Quick Plan: No need to survey the plot with clear boundary. Users can draw the
map by their hands to confirm the plot boundary, which improves survey
efficiency.
Positioning precision can reach centimeter-level. RTK components are included in
the flight control system;
Precise Spraying: It can adjust the flow rate by itself according to user's needs to
realize intelligent spray control;
Foldable Design: Both the arms and propellers of UAV are foldable, which is
convenient for storage and transportation;
User Friendly: User can send commands (such as taking off, hovering or returning)
to the UAV just by tapping a button in the ground station. Beginners can learn
basic operations in half an hour, reducing the dependence on professional
operators.
High Safety: The UAV can fly safely autonomously for 1 minute even if the satellite
signal is lost.

Data Management: The supporting agricultural data management system can help
improve operation management efficiency and increase economic value.
Intelligent Battery: 3C fast-charging is available, and the battery can be maintained
autonomously. Battery charging and maintenance more convenient than the
previous generation.
We have completed plant protection services of tens of thousands of hectares in
total for crops such as rice, corn, wheat, apple, sugarcane, banana, pitaya, grapefruit,
orange, bean and dates in many places in China. Our UAV can provide plant protection
services for different crops in different terrains.
