The problem
Weeding is expensive. There is a lack of personnel. Alternatives are in short supply.
Across Europe, farmers are facing a growing challenge: manual weeding is expensive, physically demanding, and increasingly difficult to organize – while herbicides are being restricted and socially rejected.
Our solution
Autonomous precision for real fields.
Precira is developing an autonomous robot that detects and selectively removes weeds – without chemicals, without manual labor. The system is designed for continuous use and adapts to existing agricultural processes.
Autonomous
Fully autonomous in operation, over 24 hours without interruption. No battery changes, no driver. Designed for the pragmatic field everyday – together with farmers.
Precision
Our AI detects weeds in over 99% of cases. The laser operates with millimeter precision: reliably between crops, even in dense stands.
Wet soils
Lightweight: With a total weight of less than 500 kg, the robot remains soil-friendly. No sinking in wet fields, no soil compaction – ideal for real operating conditions.
High laser power
A modern high-performance laser permanently destroys weeds. Completely without chemicals. No pesticides, no residues – maximum effect with minimal intervention.
