Episode Seven - Agricultural Robotics: Farming for the future

Robot Talk · 30 Apr 2021 · 28m · Episode 7

What this episode covers

Dr Petra Bosilj of the University of Lincoln explains that robotic vision in agriculture is bottlenecked by a lack of annotated training data for complex tasks like distinguishing weeds from crops, though precision spraying can reduce herbicide use by 80%. Chris Chavasse, founder of Muddy Machines, describes his startup's development of lightweight, swarm-capable field robots for harvesting tender stem broccoli, designed to reduce soil compaction compared to heavy industrial machinery. The episode contrasts academic research into phenotyping and soil health with the commercial challenges of building rugged, soft-robotic end effectors and securing funding during the pandemic.

    47. Robotic Farming Makes Produce Better & Cheaper

    Daniel and Forbode discuss how robotic systems are revolutionizing agriculture by addressing inefficiencies in conventional farming. They analyze two key approaches: a configurable adaptive and scalable swarm system (CASS) from Texas A&M University, which uses collaborative drones and ground robots, and Pixel Farming Robotics, a Dutch company offering modular, lightweight autonomous robots. The hosts highlight specific technologies like wireless inductive charging from Wi-Fi On and Varda batteries, emphasizing how these innovations reduce soil compaction, chemical usage, and operational costs while increasing yield.

    153. Robot Farmers Bring Back Biodiversity

    Hosts Daniel and Forbode discuss a report from the Technical University of Denmark on using agricultural robots to restore biodiversity. They explain how post-WWII monoculture farming damaged ecosystems and how small, agile robots can enable diverse crop planting. The hosts highlight the use of neuromorphic (event) cameras to allow these robots to react faster than traditional vision systems, potentially making sustainable farming viable within a decade.

    44. How Computer Vision Is Changing Your World

    Hosts Daniel and Farbod discuss how computer vision AI is applied in manufacturing and agriculture, featuring insights from Plain Sight AI and a project by the Technical University of Denmark. They explain Plain Sight AI's three levels of vision systems for detecting hazardous objects on production lines, emphasizing that Level 3 instance segmentation offers superior sorting and counting capabilities. The hosts also detail a robot developed by PhD student Ronja Goldring to autonomously remove weeds from organic dairy farms using laser or electrocution, highlighting the importance of large, diverse training datasets and collaboration with end-users.

    Willy Pell from Blue River Technology brings AI to the farm

    Willy Pell, VP of Autonomy at Blue River Technology (acquired by John Deere), explains how the company applied machine learning and computer vision to automate farming, starting with the See & Spray weed management system and expanding to the autonomous John Deere AR tractor. Pell details the strategic decision to use stereo cameras instead of LIDAR due to dust and speed constraints, and describes how the system uses deep learning to detect crops versus weeds, achieving significant herbicide savings. The episode also covers the broader roadmap for autonomous tillage, planting, and grain cart coordination, drawing inspiration from Tesla's data-driven approach to achieve full autonomy in a semi-structured agricultural environment.

    Getting Out of the Weeds with John Deere's Revolutionary AI Technology

    Chris Padwick, Director of Computer Vision and Machine Learning at Blue River Technology (a John Deere subsidiary), explains the engineering behind the See & Spray system, which uses computer vision to spot-spray herbicide on weeds. He details the massive compute requirements, noting the system uses NVIDIA Xavier and Orin GPUs to achieve 0.3 petaflops of processing power for real-time image classification at 12 mph. Padwick also discusses the critical role of data collection, the acquisition by John Deere for scaling, and the future of autonomous agricultural machinery.
