I searched our robot catalog for ground robots from other makers that carry at least 100 kg and carry an IP rating of IP54 or higher (IP54/IP65/IP67). Here is what I found:
Verified match
Unitree B2 is the only product in the catalog that meets both constraints — 120 kg rated payload and IP67. However, note that it is a legged quadruped (12 degrees of freedom, 6 m/s max speed, -20 °C to 55 °C operating range), not a wheeled or tracked UGV like your Panther. It supports NVIDIA Jetson Orin NX modules in an optional configuration. unitree.com +2unitree.com ↗“Industrial-grade IP67 quadruped robot”unitree.com ↗“robot.payload_kg=120 kg, mechanical.ip_rating=IP67”unitree.com ↗“Legged (Quadruped)”
What I could not determine
- No wheeled or tracked ground robot from another maker met both constraints. When I restricted the search to wheeled/tracked locomotion plus the payload and IP requirements, no product matched.
- I could not rule out every robot in the catalog, because most entries have no IP rating or no rated payload listed — I can only confirm matches on products where both values are published, not assume they satisfy the requirements.
- I did not find another maker's wheeled/tracked UGV with a Panther-class payload in the catalog. The closest verified alternatives would need to relax one of your two requirements, and I didn't retrieve any such candidates in this search.
So, to answer your question directly: in our catalog, Unitree's B2 is the only other maker's robot rated for 100 kg+ with at least IP54, and it is a quadruped rather than a wheeled ground robot. If a wheeled UGV with those specs is a hard requirement, I did not find one among the catalog's ground robots with confirmed ratings.
