Q: What are potential drawbacks or challenges associated with using hybrid systems in soft robotic grippers?

While hybrid systems offer a promising approach to enhancing the capabilities of soft robotic grippers, there are several drawbacks and challenges that need to be considered: Complexity: Integrating multiple technologies into a single system increases complexity both in design and operation. Managing different components effectively requires sophisticated control algorithms which may be challenging to develop and maintain. Cost: Hybrid systems often involve combining various technologies which can result in higher production costs compared to single-function systems. This cost factor may limit widespread adoption across industries. Maintenance: With more components comes an increased risk of failure or malfunction. Maintenance requirements for hybrid systems may be more demanding than for simpler designs, leading to potential downtime during repairs. Integration Issues: Ensuring seamless integration between different technologies within a hybrid system can pose technical challenges related to compatibility issues or synchronization problems between components. Scalability: Scaling up hybrid systems for mass production or industrial applications may present scalability challenges due to factors like size constraints, power requirements, or customization needs based on specific use cases.

Stats

The gripper can lift objects up to 1617 times its own weight.
Adhesion stress was found to be 1.8 kPa for preloaded metamaterial adhesive.
Applying 4 kV/mm electric field resulted in an adhesion stress of 1.6 kPa for SEM adhesive.
The enhancement ratio was approximately 60x at 6 kV/mm for wood and PVC pipes.
