Founded in 2013 in Fairmont, West Virginia, 4D Tech Solutions develops and rapidly prototypes technology for government and civilian customers, taking projects from research and system design through testing and technology transition. Its work is especially marked by unmanned systems and sensing, including a MEMS-mirror LiDAR product transitioned from Army Research Laboratory research and robotic platforms built for demanding field conditions. 4D is a wholly owned subsidiary of Accenture Federal Services and has delivered projects ranging from an Army-approved unmanned aircraft to more than 2,400 small robots for explosive-device defeat.
