Overview
The RealBot-S2 is the full-size wheeled humanoid robot with folding legs in RealMan Robotics' RealBot family. The lower body consists of folding legs with ankle and knee axes and a four-steer four-drive chassis; when the legs fold the arms drop to floor level, when they extend they reach 2.1 m, and a 0.3 m lift travel completes that range. The body measures 614 × 552 × 1700 mm and weighs approximately 125 kg. Excluding the base and end-effector there are 20 active axes: 7 per arm, pitch and yaw in the head, pitch and yaw in the waist, ankle and knee in the legs. The humanoid-configuration arms carry 5 kg, the arm span is 1778 mm without end-effector and reach is 0.69 m; each arm houses a six-axis force-torque sensor with a 200 N / 7 N·m range and 0.5% full-scale accuracy, and at the end-effector a two-finger parallel gripper and a five-finger dexterous hand swap quickly. The stereo RGB camera and two fisheye cameras in the head give 360-degree surround vision and an RGB-D camera is standard in the hands; compute runs on an NVIDIA Jetson AGX Orin 64 GB. The chassis moves at 0.1-1.5 m/s, climbs 8 degrees, crosses 20 mm obstacles and runs SLAM navigation and localization with dynamic obstacle avoidance on dual LiDAR. Modules release quickly, and OTA remote operation and maintenance deliver updates without a site visit. The 48 V 20 Ah battery runs around 6 hours in typical use; manual charging, battery swapping and automatic dock charging are supported. Connectivity is wired, Wi-Fi and optional 5G; a built-in microphone array and speaker serve voice interaction, and an optional tablet takes the place of a display. RealMan was founded in Beijing in 2018 and builds its robotic arms on its own joint modules; in 2025 it established Beijing's first humanoid robot data training center. The RealBot-S2 is built for data collection and training, home service, retail and industrial manufacturing; it is supplied to Turkey with enterprise supply, commissioning and engineering support.

RealBot-S2: Technical Analysis
Folding legs on a four-steer chassis
The lower body of the RealBot-S2 consists of folding legs with ankle and knee axes and a four-steer four-drive chassis. When the legs fold the arms drop to floor level and when they extend they reach 2.1 m; a 0.3 m lift travel completes that range. Each of the four wheels both steers and drives, so the robot turns in place and moves sideways; speed is 0.1 to 1.5 m/s, climb capability 8 degrees and obstacle crossing 20 mm. The body measures 614 × 552 × 1700 mm and weighs approximately 125 kg; SLAM navigation and localization with dynamic obstacle avoidance run on dual LiDAR.
20 axes and 360-degree head vision
Excluding the base and end-effector there are 20 active axes: 7 per arm, pitch and yaw in the head, pitch and yaw in the waist, ankle and knee in the legs. The humanoid-configuration arms carry 5 kg, the arm span is 1778 mm without end-effector and reach is 0.69 m; each arm houses a six-axis force-torque sensor with a 200 N / 7 N·m range and 0.5% full-scale accuracy. The stereo RGB camera and two fisheye cameras in the head give 360-degree surround vision, and the RGB-D cameras in the hands watch the moment of grasp. Compute runs on an NVIDIA Jetson AGX Orin 64 GB; at the end-effector a two-finger parallel gripper and a five-finger dexterous hand swap quickly.
Designed for fleet operation
Modules release quickly; maintenance and upgrades are done by swapping parts, and OTA remote operation and maintenance reduce the need for on-site intervention. The 48 V 20 Ah battery gives around 6 hours of typical operation; charging is manual, the battery can be swapped, or the robot recharges itself at an automatic dock. Connectivity is wired, Wi-Fi and optional 5G; a built-in microphone array and speaker serve voice interaction, and an optional tablet takes the place of a display. These traits move the S2 away from single-robot demonstration and towards data collection and manufacturing deployments where several robots are managed remotely on one site.
Applications
- Data collection and training: real-robot data recording through teleoperation and embodied-AI model training.
- Industrial manufacturing: line-side material handling, loading and unloading and assembly-assist tasks.
- Retail: shelf restocking, product handling and in-store service tasks.
- Home service: multi-level household tasks from floor level up to 2.1 m.
- Education and research: a folding-leg dual-arm manipulation and navigation platform.

About the RealMan RealBot-S2
RealBot-S2 Frequently Asked Questions
The most commonly asked questions and answers about RealBot-S2.
RealMan Robotics' full-size wheeled humanoid robot with folding legs: 20 active degrees of freedom, two 7-axis arms (5 kg per arm), a 0-2.1 m vertical working range, a four-steer four-drive chassis, an NVIDIA Jetson AGX Orin 64 GB and around 6 hours of runtime. It is built for data collection and training, home service, retail and industrial manufacturing.
When the ankle- and knee-axis legs fold the arms drop to floor level, and when they extend they reach 2.1 m; a 0.3 m lift travel completes the range. One robot can therefore handle a box on the floor and a product on the top shelf in the same task.
There are three paths: manual charging, battery swapping and automatic dock charging. The 48 V 20 Ah battery runs around 6 hours in typical use; on multi-robot sites battery swapping and the automatic dock provide continuous shifts.
Yes. OTA remote operation and maintenance handle software updates and diagnostics without a site visit; connectivity is wired, Wi-Fi and optional 5G. Quick-release modules reduce hardware maintenance to part replacement.
At the end-effector a two-finger parallel gripper and a five-finger dexterous hand swap quickly. Each arm houses a six-axis force-torque sensor with a 200 N / 7 N·m range and 0.5% full-scale accuracy; payload per arm is 5 kg.
It is sourced on a project basis; import, customs clearance, commissioning and engineering support are part of delivery.
