Cyclair develops autonomous agricultural robots dedicated to precision weeding in open-field crops. Through its GS and GW models, the company aims to provide growers with an efficient alternative to conventional chemical weed control by combining mechanical weeding, AI-based vision and optional targeted spraying. Its solutions are designed for a wide range of open-field crops with row spacing from 30 to 90 cm, helping farmers protect their crops while reducing labour requirements and the environmental impact of weed management.

Technology Overview

  • Latest revision : 8/4/2026
  • Commercial release date : 2024
  • Application : Cyclair’s GS and GW are autonomous precision-weeding robots designed for open-field farmers. They navigate between crop rows and remove weeds growing between plants, using mechanical weeding and, when required, targeted spot spraying.

Functionalities and technologies

  • Core Functionality : The robots use AI-based vision and environmental sensing for autonomous navigation and in-row weed detection. They operate using only field boundaries as input, navigate along crop rows, perform their headland turns and target weeds between plants when spacing exceeds 10 cm | 3.9 inches. Their in-row weeding system offers precision down to 1 cm | 0.4 inches, while the optional spot-spraying module combines mechanical and chemical weeding to ensure effective crop protection with reduced chemical use.
  • Software : Vision, LiDAR, GPS, Deep AI, Precision robotics
  • Connectivity : 3G/4/G/5G + starling GPS RTK
  • Compatible Tools : Weeding and chemicals spot spray

Development Roadmap

  • Next phase : Addition of electric weeder, addition of crop health sensor, addition of soil sensor
