When to pick which
Choose the Fourier Intelligence GR-1 for industrial pilots or university research labs requiring heavy-duty manipulation and deep software customization. Its 50kg payload capacity—over four times that of the Panther—makes it the superior choice for light manufacturing tasks involving heavy lifting or rehabilitation R&D where supporting human weight is critical. With 40 degrees of freedom and a ROS2-compatible open-platform stack, it suits developers building complex teleoperation systems or proprietary AI models. While more expensive, its high payload-to-weight ratio and open SDKs justify the investment for teams prioritizing mechanical strength and software flexibility over long-duration autonomous patrol.
Opt for the UniX AI Panther for large-scale commercial deployments or long-shift service roles in hospitality and property security. The standout feature is its 8-hour runtime, which significantly outperforms the GR-1’s 2-hour limit, making it viable for full-shift operations without frequent battery swaps. At a lower $115,000 price point, it is better suited for fleet scaling in retail or elderly care environments where 2 m/s movement speed and vertical reach are more valuable than raw lifting power. Its proprietary UniFlex and UniCortex SDKs target users seeking a more integrated, ready-to-deploy solution for household chores and logistics.
