Didge NX (operating as Didge, from Nextera Robotics) builds autonomous mobile robots and a vision-AI platform that continuously digitize active construction sites. Its wheeled and tracked robots drive themselves around a jobsite daily — climbing stairs or riding human-operated hoists — capturing 360-degree imagery that the platform turns into progress tracking, safety monitoring, quality inspection and automated documentation. The neural networks are trained on data from thousands of miles driven inside live construction sites, and the platform integrates with Procore, Autodesk and Oracle project tools. The company was founded at MIT, went through Y Combinator, and has taken strategic equity investment from Oshkosh Corporation and its JLG access-equipment business.
