  • ­A Farmer-Assistant Robot for Nitrogen Fertilizing Management of Greenhouse Crops
    Computers and Electronics in Agriculture Journal, June 2017
    Product: Nitrogen Fertilization Robot
    Environmental Impact: Improve nitrogen fertilization efficiency in greenhouse crops
    Planetary Boundary: Biochemical Flows 
    Keywords: Autonomous machine vision-based system, Nitrogen fertilizing management, Image processing, Image textural features, Biochemical flows, Chemical pollution, Ground robotics, Preventive solution
    Description: This autonomous robotic system was developed for precise nitrogen fertilization for greenhouse crops (e.g. tomatoes, lettuce, peppers). The system was tested using a machine vision-based scenario and was found to be able to decrease the crops’ nitrogen fertilizer consumption by about 18%.

  • Automated Robotic Assay of Phosphomonoesterase Activity in Soils
    Soil Science Society of America Journal, 01 March 2006
    Product: Automated Testing Robot
    Environmental Impact: Monitoring and recording chemicals within the soil
    Planetary Boundary: Biochemical Flows
    Keywords: Zymark XP laboratory robotic system, Phosphomonoesterase measurement, Biochemical Flows, Ground robotics, Preventive solution
    Description: This study found that using a robotic system for measuring phosphomonoesterase activity in soils differing in physical and chemical characteristics was comparable in both accuracy and precision to manual procedures, yet the robotic system resulted in considerable savings in cost and labor.

  • Reducing Air Pollution with hybrid-powered Robotic Tractors for Precision Agriculture
    Biosystems Engineering Journal
    , March 2016
    Product: Farming Assistant Robot
    Environmental Impact: Reduces carbon emissions from the farming process 
    Planetary Boundary: Climate Change 
    Keywords: Robotic tractor, Precision agriculture, Atmospheric emission, Atmospheric air pollution, Ground robotics, Preventive solution
    Description: The emissions from robotic tractors with a hybrid energy system for precision weed and pest control were compared with those from tractors with a combustion engine as a single power source. The hybrid energy system was designed by adapting the original energy systems of the tractors to reduce atmospheric pollution emissions. The results of the study found that the hybrid system reduced emissions by 50% in the best case.

  • Vision-Based Robotic System for On-Site Construction and Demolition Waste Sorting and Recycling
    Journal of Building Engineering, August 2020
    Product: Waste Sorting Robot 
    Environmental Impact: Makes the recycling process more efficient 
    Planetary Boundary: N/A

    Keywords: Construction, and demolition waste (CDW), CDW management, CDW recycling, Waste Sorting, Soil pollution, landfills, Autonomous mobile robots, Ground robotics
    Description: Prototype pick-and-place system for sorting irregular construction and demolition waste (CDW) using “instance segmentation on uneven surfaces” and SLAM. This is a new solution for picking and sorting CDW, and it was proven to be effective and efficient through practical experiments.
