Classifying mechanical links
Slide subtitle or context (optional)...
- ●Rigid links maintain constant distance between points
- ●Designed to transmit force without deformation
- ●Commonly made from steel or carbon fiber
- ●Used in industrial robot arms and chassis
- ●Soft links allow controlled deformation
- ●Utilize elastomers or pneumatic actuators
- ●Enable safe human-robot interaction
- ●Used in surgical tools and soft grippers
