REX system: autonomous robotic plant sampling for DNA extraction
The REX System combines micro needle array technology and autonomous robotics to extract plant DNA samples in greenhouses. This innovative method is less destructive than traditional techniques and offers automation potential for scalable plant research.
Overview
The REX System is an advanced robotic solution designed to autonomously extract leaf samples from plants in greenhouses, specifically targeting DNA extraction. Developed by Carnegie Mellon University and Virginia Tech, this system employs micro needle array technology to efficiently and gently obtain plant DNA, reducing the destructiveness associated with traditional cutting methods. By integrating this technology with an autonomous robotic platform, the REX System offers a promising approach to streamline plant research and data collection in controlled environments.
Technical specifications
Key features:
- Utilizes micro needle arrays for non-destructive DNA extraction from plant leaves
- Autonomous robotic platform capable of 3D modeling and plant interaction
- Proposed enhancements include a simplified robot arm and end-effector design for improved functionality
- Integration with a commercially available gantry system for increased automation
The system's design facilitates the automation of DNA extraction, amplification, and library preparation, crucial for sequencing plant DNA. This innovation not only aims to enhance the efficiency of plant sampling but also supports scalability across different crop types.
Technology readiness level
The REX System currently stands at Technology Readiness Level 3. Initial prototypes have been developed and tested in controlled environments, with further validation planned to refine the technology. The next steps involve optimizing the robotic components and validating the micro needle extraction method against traditional techniques, aiming to bring the system closer to a turn-key solution for researchers and agricultural professionals.
