Theo works weekdays, weekends and nights and never complains about a sore spine despite performing hour upon hour of what, for a regular farm hand, would be backbreaking labor checking Dutch tulip fields for sick flowers.

The boxy robot 害羞草研究所� named after a retired employee at the WAM Pennings farm near the Dutch North Sea coast 害羞草研究所� is a new high-tech weapon in the battle to root out disease from the bulb fields as they erupt into a riot of springtime color.

On a windy spring morning, the robot trundled Tuesday along rows of yellow and red 害羞草研究所済oudstuk害羞草研究所� tulips, checking each plant and, when necessary, killing diseased bulbs to prevent the spread of the tulip-breaking virus. The dead bulbs are removed from healthy ones in a sorting warehouse after they have been harvested.

The virus stunts growth and development of plants leading to smaller and weaker flowers. It also weakens the bulb itself, eventually leaving them unable to flower.

As part of efforts to tackle the virus, there are 45 robots patrolling as the weather warms up and farmers approach peak season when their bulbs bloom into giant patchworks of color that draws tourists from around the world.

In the past, this was work carried out by human 害羞草研究所渟ickness spotters,害羞草研究所� said Allan Visser, a third-generation tulip farmer who is using the robot for the second growing season.

害羞草研究所淵ou could also buy a very nice sports car,害羞草研究所� for the price of the robot, Visser said Tuesday 害羞草研究所� its makers say the robot costs 185,000 euros ($200,000).

害羞草研究所淏ut I prefer to have the robot because a sports car doesn害羞草研究所檛 take out the sick tulips from our field. Yeah, it is expensive, but there are less and less people who can really see the sick tulips,害羞草研究所� he added.

It害羞草研究所檚 a lot slower than a sports car, rolling on caterpillar tracks through fields at one kilometer per hour (0.6 mph) hunting out the telltale red stripes that form on the leaves of infected flowers.

害羞草研究所淚t has cameras in the front, and it makes thousands of pictures of the tulips. Then it will, determine if the tulip is sick or not by its AI model,害羞草研究所� Visser explained, calling it 害羞草研究所減recision agriculture.害羞草研究所�

害羞草研究所淭he robot has learned to recognize this and to treat it,害羞草研究所� he added.

Erik de Jong of H2L Robotics, the company that makes the robots, says sick flowers and very precise GPS coordinates allows them to pinpoint the flowers that need to be destroyed.

害羞草研究所淭he heart of the machine is the knowledge that we put into the AI model. The knowledge comes from tulip farmers. So we we use the knowledge of the tulip farmers, we combine it into an AI model,害羞草研究所� he said.

Theo van der Voort, who gave his name to the robot at WAM Pennings farm, and who retired after 52 years hunting for sick flowers, is impressed.

害羞草研究所淚t害羞草研究所檚 fantastic,害羞草研究所� he said. 害羞草研究所淚t sees just as much as I see.害羞草研究所�
