Developed by LinkerBot (Beijing) Technology Co., Ltd., the Linker Arm A7 (Model LA7‑01‑V2) is a 7‑degree‑of‑freedom commercial robotic arm designed for embodied intelligence and lightweight application scenarios. Its 7‑DOF design enables flexible posture adjustments and complex motion trajectory planning, while the integrated motor, driver, and planetary gearbox structure ensures compact construction and efficient power transmission. The classic mechanical configuration combined with 7 degrees of freedom allows the A7 to adapt to a wide range of complex application scenarios, providing stable and reliable automation solutions across different industries.

Key Features

• 7 Degrees of Freedom for Superior Flexibility – Each joint features a wide rotation range, delivering exceptional flexibility and motion redundancy. The 7‑DOF design enables precise trajectory planning and flexible posture adjustments, easily handling complex operational requirements.

• Lightweight Design with Impressive Payload Capacity – Weighing only 6.5 kg, the A7 is a lightweight robotic arm that is easy to deploy and relocate. Despite its compact form, it delivers a rated payload of 3 kg and a working radius of 580 mm, achieving both “flexible deployment” and “reliable operation” in lightweight applications. The static maximum load capacity reaches 10 kg, with a load‑to‑weight ratio of 0.488.

• High Speed for Efficient Operation – Maximum joint speed reaches 360 rpm, enabling rapid motion execution. This makes the A7 ideal for sorting, assembly, and other scenarios where operational efficiency is critical.

• High Precision and Repeatability – With a repeat positioning accuracy of ±0.076 mm, the A7 ensures consistent, high‑precision performance across repeated tasks.

• Robust Communication and Power – CAN communication protocol ensures stable, real‑time data transmission. Operating voltage is 48V, with static power consumption of 27.7 W and maximum power of 324 W.

• Wide Temperature Range – Operates reliably from -20°C to 50°C, suitable for diverse deployment environments.
