The lightest Jetson Orin NX-based humanoid in our catalog is the Booster K1 Education, at 19.5 kg — by a wide margin over the other Orin NX humanoids, which start at 35 kg.
It's also well suited to the classroom-carry scenario your teaching assistants have in mind: it's a small 0.95 m, 22-DoF humanoid robot whose controller is an NVIDIA Jetson Orin NX 8GB module rated at 117 TOPS. docs.boost... +2docs.booster.tech ↗“19500 g”docs.booster.tech ↗“0.95 m, 22-DoF small humanoid robot”docs.booster.tech ↗“Jetson Orin NX 8GB rated at 117 TOPS”
For comparison, the next-lightest Orin NX humanoids with a listed weight are:
| Product | Weight | Height | Jetson module |
|---|---|---|---|
| Booster K1 Education | 19.5 kg | 950 mm | Orin NX 8GB (117 TOPS) |
| Unitree G1 EDU | 35 kg | 1320 mm | Jetson Orin NX |
| ROBOTIS AI Sapiens K1 | 35 kg | 1355 mm | Orin NX 16GB |
| AgiBot X2 Ultra | 39 kg | 1310 mm | Orin NX (157 TOPS) |
| Unitree H1 | 47 kg | 1800 mm | Jetson Orin NX |
| LimX Oli EDU | 55 kg | 1650 mm | Orin NX 16GB (157 TOPS) |
A few Orin NX humanoids (Unitree G1-D, PAL KANGAROO Pro, EngineAI PM01, Apptronik Apollo) have no weight listed in the catalog, so they can't be ranked — though the G1-D and PM01 are compact models that may also be worth a look.
