4D1 launches T2 for rugged, millimeter-level 3D indoor positioning - The Robot Report

4D1 has launched the T2, a precise indoor positioning system designed to deliver millimeter-level 3D positioning with six degrees of freedom (6DoF) for industrial environments such as factories and process-centric industries. The T2 system addresses common challenges in indoor positioning like accuracy loss, drift, and bulky hardware by providing drift-free, real-time location tracking that includes full orientation for both robots and human operators. Its rugged, compact design is IP54-rated for dust and water resistance, making it suitable for harsh industrial settings. The system uses advanced sensor fusion, combining ultrasonic signals with an inertial measurement unit (IMU), enabling calibration-free operation and rapid deployment with existing industrial equipment. 4D1 emphasizes that T2 facilitates seamless collaboration between humans, robots, and AI systems, enhancing efficiency, safety, and productivity on the shop floor. The system generates AI-ready operational data that supports task validation, faster workforce upskilling, and actionable insights, contributing to smarter decision-making and AI-driven
