Evaluation Criteria
Payload & Reach
You should always consider payload and reach when choosing a robot arm for precision assembly. Payload refers to the maximum weight the robot can handle, while reach is the distance the arm can extend. For small-scale assembly, most user-friendly cobots offer payloads under 10 kg and reach up to 1 meter. Studies show that higher payload and longer reach expand your assembly options and improve performance. Articulated arms with more axes can work across multiple stations, making them ideal for flexible production lines. When you match payload and reach to your specific tasks, you ensure consistent quality and efficient operations.
Precision
Precision is critical for quality and reliability in precision assembly. You want a robot arm that can repeat the same motion with minimal error. Research shows that many industrial robotic arms achieve repeatability between ±0.02 mm and ±0.1 mm. High-precision models reach up to ±0.02 mm, which is essential for micro-assembly and electronics. The PLOS One study confirms that a 5-DOF lightweight manipulator can achieve 0.05 mm repeatability, matching commercial standards. Environmental factors, calibration, and end effector quality all affect precision. Reliable precision ensures your products meet strict quality standards every time.
