A 200-hectare farm in Tay Ninh buys 3 spraying drones for 2 billion VND, expecting to replace 30 workers. Three months later, 2 drones sit idle for lack of technicians, 1 is fined for unlicensed flight. Farm automation is not “buy a robot and done” — the equation lies in operation, legal compliance, and people, with the purchase price only the first line.
What do farm robots include?
Common today: drones for spraying, fertilizing, seeding, and field mapping; autonomous tractors and harvesters (partial or full); harvest robots (fruit picking, greenhouse cutting); automated greenhouse systems (irrigation, fertigation, climate control). Each has different cost structures and legal requirements — they cannot be lumped as “buying robots”.
Drones: flight needs a permit
Where most farms stumble: drones (unmanned aircraft) are governed by Decree 36/2008/ND-CP on unmanned aircraft and ultralight vehicles. The rule: flight requires a permit — apply in advance to the competent authority (the Operations Department, General Staff), issued within the prescribed time; with prohibited acts (no-fly zones, endangering safety…). An expensive drone flown “underground” becomes scrap metal, plus fines and confiscation.
The financial equation: depreciation and hidden costs
The purchase price is only part: depreciation of hi-tech equipment is fast (obsolete in 3–5 years); operating costs (batteries, parts, maintenance, software); personnel — drone/robot technicians are scarce and far costlier than manual labor; insurance for equipment and third-party robot accidents. Compute total cost of ownership over the equipment lifecycle before comparing with labor costs — many farms find robots pay off only at sufficient scale with continuous operation.
Labor safety and liability
Robots do not erase OSH duties under the OSH Law 84/2015/QH13 — they shift risks: collisions with workers, chemical leaks from spraying drones, software failures. Farm owners need dedicated safe-operation procedures for automated equipment, training for staff working alongside robots, and liability insurance. When a robot injures a third party, civil liability falls on the equipment owner/manager — purchase contracts should clearly allocate manufacturer warranty and product-defect responsibility.
Frequently Asked Questions
1. What permits are needed to buy a spraying drone?
Distinguish: buying and owning a drone differs from being allowed to fly. Drone flight (with exceptions) requires a flight permit under Decree 36/2008/ND-CP. Operators need training; some localities add no-fly rules.
2. Who is liable when a robot injures a worker?
The farm owner (employer) compensates the worker under labor and OSH law; and may pursue the manufacturer/supplier if a technical defect caused it — provided the purchase contract has clear warranty and product-liability clauses.
3. Should we hire drone services instead of buying?
For small and mid-size farms, hiring per-season drone spraying is usually more efficient: no capital outlay, no maintenance worries, the provider handles flight permits and operation. Buy only with large acreage, high usage frequency, and in-house technicians.
