Food-Grade Soft Gripper for Collaborative Robots
SKU
soft-gripper
The Soft Gripper is an electrically actuated, adaptive end-of-arm tool designed for collaborative robot applications where traditional rigid grippers are not suitable. Using flexible, compliant fingers, the gripper conforms to part geometry rather than relying on precise positioning or fixed gripping surfaces.
This approach allows a single gripper to handle a wide range of object shapes, sizes, and surface conditions while maintaining controlled gripping forces suitable for collaborative environments.
The Soft Gripper is commonly used in applications where product variation, fragility, or surface sensitivity makes conventional parallel or rigid grippers impractical.
Key Features and Capabilities:
- Soft, compliant gripping fingers that adapt to part geometry
- Designed for handling fragile, irregular, or variable-shaped objects
- Electrically actuated for simplified cobot integration
- Adaptive gripping reduces dependency on precise part positioning
- Single gripper can handle multiple product types
- Designed for collaborative robot payload and safety constraints
Gripping performance is achieved through finger compliance rather than high mechanical force.
Note: A combination of the below options are included with your purchase depending on the model selected:
- 1x robot side quick changer
- 1x tool mounting flange
- 1x cabling kit
- 1x robot kit (The robot kit is required for Ethernet IP communication and software updates for all OnRobot tooling.)

Integration with Collaborative Robots
The Soft Gripper is designed for direct use on collaborative robots and aligns with typical cobot integration requirements, including compact size and electrical actuation. It is part of the collaborative EOAT ecosystem from OnRobot, supporting deployment across multiple cobot platforms depending on interface and configuration.
Final robot compatibility depends on the selected robot flange, electrical interface, and control environment.
When a Soft Gripper Is the Appropriate Choice
A soft gripper is typically selected when:
- Parts vary in size, shape, or orientation
- Surface damage must be minimized
- Precise part alignment cannot be guaranteed
- One gripper must support multiple SKUs
- Frequent mechanical changeover is undesirable
It is not intended for high-force gripping or precision fixturing tasks.
Adaptive electric soft gripper for collaborative robots, designed to handle fragile and irregular objects through compliant gripping rather than rigid force.
