OTC DAIHEN FD-B4S – Highly Flexible 7-Axis High-Speed Robot

Integrated Cable Routing • Advanced Redundancy Kinematics • Compact High-Density Layout

The OTC DAIHEN FD-B4S is a cutting-edge, 7-axis vertical articulated industrial robot engineered to provide unmatched freedom of movement, agility, and precision path execution. Featuring a unique 7th rotational axis configuration, the FD-B4S specializes in dynamic obstacle avoidance within highly crowded or restricted welding zones. Unlike standard 6-axis configurations, it can freely alter its structural arm posture while holding the exact position and attitude of the end-of-arm tool completely constant. Built with a sleek, through-arm hollow shaft structure, all core utility lines and heavy welding cables are integrated entirely inside the 7th axis mechanism. This eliminates exterior snags, slashes teaching downtime, and significantly boosts overall arc quality and production line efficiency.

Key Features & Design Advantages

• 7-Axis Kinematic Redundancy: Rotates smoothly around bulky parts or tight fixtures to reach internal seams, frequently eliminating the need for expensive external component positioners.
• Fully Enclosed Internal Routing: Keeps torch coaxial connections, electrical signal lines, and pneumatic supply conduits protected internally, ensuring zero component wear from external rubbing.
• Coordinated Teaching Software: Advanced trajectory math controls the 7th joint automatically, simplifying manual teach-pendant manipulation into intuitive directional paths.
• High Rigidity & Tracking Precision: Powered by premium 3,550W AC servo drives to maintain an industrial repeatability rating of ±0.08 mm.
• Space-Saving Work Envelope: The narrow arm profile fits tightly against neighboring machines to achieve ultra-compact, multi-robot manufacturing cell arrangements.
