7-Axis Collaborative Robots

7-Axis Collaborative Robots: Redundant flexibility for confined spaces

Unlike standard models, a 7-axis collaborative robot offers an additional (redundant) degree of freedom, allowing the robotic arm to maneuver around obstacles and operate in extremely compact spaces without changing the position of its end-effector. This AUCTECH series is specifically designed for flexible production lines where layouts are dense and precision is critical.

Equipped with advanced features such as collision detection and traction teaching (hand-guided programming), the 7-axis cobot eliminates barriers between human and machine, facilitating safe and intuitive collaboration.

Technical description: High-Resolution performance

The 7-axis X Series (models X5-7A and X3-7A) redefines industrial maneuverability standards:

• Superior agility: The 7 degrees of freedom allow the robot to execute complex motions, making it ideal for precision assembly, polishing, and testing tasks.

• Extreme precision: Repeatability of up to ±0.02mm ensures perfect consistency in micro-assembly or technical inspection processes.

• Energy efficiency: Low power consumption (approx. 250W) makes this equipment a sustainable and cost-effective solution for modern factories.

• Rapid deployment: The modular design and lightweight build allow for quick redeployment across different segments of the production flow.

Why choose this equipment? 

• Outstanding freedom of movement: The seventh axis allows the robot's "elbow" to move independently, facilitating access inside machinery or into areas where a 6-axis robot would be obstructed.

• Native safety: The collision detection function allows for operation without safety fencing, as the robot stops instantaneously upon contact with personnel.

• Zero-Code programming: Traction teach technology enables operators with no prior programming experience to manually guide the arm to learn new trajectories.

• Industrial Versatility: Ideal for the 3C Electronics, Medical, Automotive, and Education sectors.

FAQ – 7-Axis Collaborative Robots 

What is the main advantage of a 7-axis robot over a 6-axis one?

The seventh axis provides "kinematic redundancy." This means the robot can maintain the same Tool Center Point (TCP) position while reconfiguring its arm joints to avoid environmental collisions or to optimize the working angle in tight spaces.

Is safety fencing required for AUCTECH 7-axis robots?

No, these robots are designed for direct collaboration. The force monitoring and collision detection functions allow for safe operation alongside humans, complying with international robot safety standards.

In which industries is the use of 7-axis robots recommended?

Due to their ±0.02mm precision and high flexibility, they are especially recommended for 3C electronics assembly, medical product testing, complex surface polishing, and CNC machine tending with difficult access points.

How difficult is it to program such a complex robot?

Despite having an extra axis, programming is simplified through the traction teaching function. The operator can manually move the arm to the desired points, and the software automatically records the optimal redundant trajectory.
