Spring sowing brings hope as seedlings break through the soil. Autumn harvest fills the barn with fruit. Every gain in farming efficiency and every increase in income depends on precise control and stable operation of agricultural machinery.
For LJ Tech, product quality is not just theoretical data on a computer. It is proven strength — tested again and again in real fields. To ensure our agricultural robots perform well in extreme conditions and support efficient work during busy seasons, LJ Tech sends a testing team to a lychee orchard in Hainan every year after the Spring Festival. This year is no different. We use real environments as our test paper and extreme conditions as our ruler. Then we refine every detail of our products and verify reliability that goes beyond expectations.
A Natural Testing Ground: Extreme Conditions in Hainan
After the Spring Festival, most parts of China are still cold. Fields are not fully green, so it is hard to simulate real busy‑season work. But Hainan’s tropical climate creates a unique natural testing ground. It is hot and humid. Humidity often stays above 85%. Afternoon temperatures can rise past 35°C. The lychee orchard is dense with leaves and branches. The air feels sticky and heavy. This is the perfect place to test a machine’s environmental adaptability. Only under such extreme natural conditions can we find hidden problems and improve performance.
Hardcore Testing: Sharpening Product Strength
The testing team brought two core products from LJ Tech to Hainan: the S500Pro Agricultural Robot with its small fan module, and the S1000 Agricultural Robot. The tests focus on core performance and real operational needs. They go step by step, carefully and strictly. No “just going through the motions.”
For the S500Pro with the small fan module, the tests cover two areas: basic parameters and key components.
Basic parameter tests: Engineers repeatedly adjust equipment angles, accurately calculate total vehicle weight and fuel consumption, and make sure every data point matches real working conditions. This provides a precise basis for later improvements.
Key component and structure tests: They check driving speed stability, tank sealing and capacity, supercapacitor endurance and charge/discharge efficiency, pump delivery power, and long‑term durability of the whole machine. Each test mimics the high‑intensity rhythm of the busy farming season, so the product can withstand continuous operation.
For the S1000 Agricultural Robot, tests focus more on full verification of core functions.
These include output stability of the drive system, response sensitivity of the drive parts, and accurate performance of key functions. Safety testing is a top priority. It covers three areas: general safety, unmanned mode safety, and remote control mode safety. Engineers repeatedly simulate different sudden scenarios to check every possible risk. At the same time, failure rate, sealing, and ease of use — all closely related to user experience — are also key test points. In addition, the team runs special tests based on the features of tropical orchards like the lychee farm.
Closing the Loop: From Testing to Improvement
Behind these extreme tests is the hard work of the testing team, day after day. The harsh environment adds even more challenges. For example, the lychee orchard is dusty. Dust and sand from leaves, branches, and soil stick to the equipment and get inside, making testing harder. Also, snakes, rats, and insects are common in the tropical environment — an extra nuisance during the tests.
The weather in Hainan changes quickly. Rain often comes without warning. Sudden heavy rains quickly soak the orchard, turning the ground muddy. This seriously affects the testing. The muddy ground makes it hard for the test vehicles to move. The changing environment directly makes test data unreliable. As a result, the planned tests have to stop and be postponed.
After each day of testing, the engineers immediately do a full check and maintenance of the test vehicles. This includes cleaning dust off the air filters so dust does not block the system, and cleaning mud off the chassis while checking for loose or worn parts. They export the day’s test data, check it one by one, and look for any small abnormalities. The team also fully inspects the wear on all vehicle parts and replaces damaged ones right away, so the next day’s testing can go smoothly.
During the day, the lychee orchard is a battlefield for testing. At night, their living place becomes a base for data review and problem solving. The team goes over every data set and every test log from the day. They list every problem and every abnormal situation clearly, gather them together, and quickly send feedback to the R&D team.
The tests are still going on. LJ Tech has always believed that good products can survive all kinds of extreme environments and meet the high demands of the busy farming season.
