Weiyi Technology Unveils Humanoid Force-Control Arms and Dual-Arm Controller for Industrial and Home Use
Humanoid products in embodied AI are polarizing: some focus on heavy industrial payloads but lack fine, compliant manipulation, while others target home demonstrations and struggle with stable, long-term factory production.
Shanghai Weiyi Technology has developed self-researched high-precision force-control joint modules and a dual-arm cooperative controller to create a humanoid force-control arm matrix. It applies one underlying force-control technology to both industrial lines and home service.
The arms can perform assembly, grinding, and palletizing in factories, and also handle household chores, item organization, and delicate operations at home, enabling cross-scenario deployment with one force-control stack.
Unlike split control and external six-axis force sensor stitching, Weiyi's dual-arm cooperative controller is deeply customized for dual-arm force control. It serves as the computing and control core of the system, supporting industrial stability and home safety from the same architecture.
1. Native full-domain joint force-control closed loop: instead of adding force sensors at the end effector, each joint has built-in torque sensing for millisecond-level hybrid force-position adjustment. In industrial conditions, it resists impact and adapts to workpiece tolerances; in home environments, it is gentle on contact, grips fragile items without crushing them, and ensures safe human-robot interaction.
2. Millisecond dual-arm synchronization: it supports human-like two-handed work, with one hand holding and the other operating. In factories, this enables cooperative assembly and two-sided grinding; at home, it supports two-hand organizing, storage, and holding vessels.
3. Full-model compatibility with one controller: the controller adapts to 10 kg, 20 kg, and 50 kg dual-arm gradients. Industrial heavy-load models pursue long-term stable output, while home light-load models emphasize compliant interaction. A unified debugging interface lowers the threshold for secondary development.
4. Dual-mode safety system: industrial mode supports long continuous operation and production-line safety logic; home mode enables flexible force limiting and collision buffering, releasing force immediately upon human contact to protect the living environment.
The full-gradient humanoid force-control product matrix spans industrial and home scenarios. The cooperative dual-arm series covers factory heavy-load and home compound tasks with human-like two-handed operation.
The 10 kg humanoid cooperative dual-arm model is a benchmark for small and medium-sized collaboration. On the industrial side, it handles two-hand assembly of complex components, gripping and aligning irregular parts, cooperative dispensing, and medium material transfer. At home, it supports two-hand organizing, folding large garments, and carrying boxes, completing two-handed tasks that a single arm cannot.
The 20 kg humanoid cooperative dual-arm model is a general medium-load option. Industrially, it covers material handling, box docking, loading and unloading parts, and heavy component assembly. For home and commercial use, it moves large storage boxes and household heavy objects, balancing payload with safe compliance.
The 50 kg heavy-load humanoid cooperative dual-arm model is the flagship. Industrially, it targets large material transfer, full-box palletizing of finished goods, and loading and unloading in warehousing and logistics. It maintains native force control while retaining high payload, avoiding rigid impacts that damage workpieces, and is designed for future large home or warehouse compound scenarios requiring bulky material transfer and stacking.
In industrial scenarios, the series serves as a flexible manufacturing mainstay. Flexible precision assembly performs snap-fit pressing, gap alignment, part insertion and removal, and compliant fastening, adapting to workpiece tolerances and preventing damage to thin-walled parts. Constant-force grinding and deburring polishes irregular curved surfaces with stable force, ensuring surface consistency across batches. Dual-arm collaboration lets one arm hold a workpiece while the other grinds, assembles, or dispenses. Logistics and palletizing handle material transfer, box loading and unloading, and finished-product stacking, replacing repetitive heavy manual work.
In home scenarios, the series acts as a general domestic assistant with compliance and safety for living environments. Native joint force control allows fine grip-force adjustment with safety first. Household organization includes tidying clutter, folding clothes, and cleaning surfaces. Object operations include handling tableware, watering plants, and moving storage boxes. Assisted care includes delivering items and simple chores, with automatic compliant buffering upon human contact to ensure safe home interaction.
From flexible assembly, grinding, and palletizing in factory workshops to household organization and material handling in home spaces, Weiyi's humanoid force-control arms use human-like two-handed collaboration to connect industrial mass production with general home operations, pushing embodied AI from lab demonstrations into real-world deployment.
