When to pick which
Choose the Agility Robotics Digit v4 for high-throughput logistics and fulfillment centers requiring immediate commercial deployment. This robot is the better investment for warehouse managers focused on tote handling or truck unloading where operational uptime is non-negotiable. Its four-hour runtime and hot-swappable battery system support multi-shift cycles that the GR-1 cannot match. Furthermore, the Agility Arc cloud platform provides the enterprise-grade fleet management tools necessary for scaling beyond a single pilot unit. Select this model if your priority is a rugged, production-ready bipedal platform integrated into existing industrial workflows via a ROS2 bridge.
Select the Fourier Intelligence GR-1 for university laboratories or corporate R&D departments focused on advanced manipulation and human-robot interaction. With 40 degrees of freedom, it offers significantly higher mechanical dexterity than the Digit v4, making it the preferred choice for teleoperation studies and rehabilitation research. The $100,000 lower price point allows institutions to deploy multiple units for swarm or collaborative testing on a limited budget. Despite the shorter runtime, its 50kg payload capacity and open-platform Fourier OpenAI Stack provide the flexibility needed for experimental light manufacturing pilots where high articulation is more valuable than continuous shift endurance.
