ZERITH H1

Reach rather than strength is the trade-off behind ZERITH H1 from Hefei: each of its two seven-axis arms is rated for just 1 kg, 1.5 kg at most, yet reaches up to 2.16 m, and a lift in the waist adjusts the overall height between 0.96 and 1.76 m. The robot weighs 111 kg and has 23 degrees of freedom: 2 in the head, 7 per arm, 3 in the waist including the lift, 2 in the differential-drive chassis and 1 in each end effector.

Repeatability is 1.5 mm and travel speed 1 m/s. A swappable 20 Ah battery, voltage unstated, lasts 4 to 7 hours depending on use; a 54.6 V, 10 A mains adapter allows tethered operation. Sensing comprises a 6-axis IMU, a depth camera in the head, a second depth camera on the wrist, LiDAR and a speech-recognition module.

The onboard computer pairs a 20-core, 28-thread CPU with 32 GB DDR5, a 1 TB SSD and an NVIDIA RTX 5060. An open SDK in Python and C++, a complete URDF for sim-to-real transfer and a reaction latency below 10 ms make it a teaching and research tool; the maker also names instant-retail warehouses, robot kiosks and data-collection centres.

The company, led by founder Min Yuheng, quotes prices only through a telephone hotline, so the catalogue lists price on request. Its earlier bipedal project is Zerith Z1.
