Lumen S1 (光子 S1)

Sized for classrooms and exhibition stands, the Lumen S1 from HECbot in Wuhan measures 130 cm and weighs 35 kg. The body offers 31 degrees of freedom before the five-finger dexterous hands are counted; the maker does not state how many axes the hands add. End-effector payload is 3 kg. A 500 Wh battery runs for two hours, after which the pack can be swapped or the robot docks to recharge on its own.

Sensors are spread across the body: a chest LiDAR, an RGB-D depth camera, a front stereo RGB pair, a rear RGB camera, a dedicated interaction camera and a touch sensor on the head. Computing is handled by an NVIDIA Jetson Orin NX with 157 TOPS, 16 GB of memory and a 512 GB SSD. The software speaks Chinese and English, carries an emotion model and recognises faces.

Connectivity covers 4G/5G, WiFi, Bluetooth and two Gigabit Ethernet ports, and 12 V and 48 V outputs power add-on modules, a useful detail for universities and integrators. Walking speed is not published. The S1 is meant for reception, exhibitions, companionship and teaching, with education, research, care and entertainment as target groups.

Its shipping status follows from the series deliveries of the Lumen line, which also includes the full-size Lumen H1. Price on request.
