YMBot D4

YMBot D4 is a heavy-load industrial wheeled humanoid from YMBot (Jiangsu Yunmu Intelligent Manufacturing) in Taicang, first shown at the 2026 World Artificial Intelligence Conference in Shanghai. It is built around two arms that can carry 60 kg together, 30 kg each, with high-precision motion control that YMBot says places loads to within a millimeter. A vertical lifting platform with an 800 mm stroke lets it work from the floor up to 2 m. It stands 1820 mm tall on a base measuring 800 by 680 mm, has 27 degrees of freedom without end tools, and drives at up to 1.5 m/s on a four-steer, four-drive omnidirectional chassis. Two 48 V, 30 Ah batteries run it for about 8 hours and can be swapped quickly. It sees with stereo and RGB-D cameras, a fisheye camera and LiDAR, and feels loads through a six-axis force sensor. YMBot reports a redundant power system in the chassis that lets it stop safely if one drive fails, plus an emergency stop and several layers of safety protection. It runs YMBot's Primitive X industrial model, connects by Wi-Fi, 4G/5G and Bluetooth, and offers low-level joint and sensor interfaces with ROS2 compatibility. YMBot aims it at heavy manufacturing, logistics handling and other jobs that replace high-risk, high-intensity manual work, completing the light, medium and heavy tiers of its industrial line.
