Potential for higher productivity
Lower moving mass can enable faster working cycles when motion limits the cycle time. Drives and controls must support the change.
Application & Value
Lightweight Composite Robot Arm
Less moving mass for precise, dynamic motion.
Challenge
Robot arms must move loads quickly and precisely. Their own weight loads the drives, while deflection and vibration affect positioning.
Solution approach
Fibre-reinforced arm structures combine low moving mass with high stiffness. Their construction addresses loads during movement, while connections and joints transfer the forces. This allows the structure to support precise motion while limiting the structural weight carried by the drives.
The benefits
Stable positioning
A stiff structure limits deformation under load and supports repeatable motion.
Lower energy demand per cycle
Less mass to accelerate can reduce drive loads and energy demand. The effect depends on the motion profile.
What could this mean for your product?
In moving systems, structural weight also affects the demands on drives and control. A lighter structure with sufficient stiffness can therefore create benefits beyond the component itself. For other handling tasks, duty cycle, reach and payload should be considered together when assessing this potential.
