OnRobot Soft Gripper
One-line judgment
For actually grasping flowers without damage, OnRobot Soft Gripper may be more practical than a dexterous hand as the first end-effector. It is weak at in-hand manipulation, but its compliant contact is exactly the point.
Overview
OnRobot Soft Gripper is a commercial soft gripper for food, produce, and irregular fragile objects. It is not a dexterous humanoid hand, but for real flower handling, the ability to hold petals and stems without damage may matter more than high-DoF in-hand manipulation.

Fit for Flower Handling and Bouquet Making
| Criterion | Assessment |
|---|---|
| Petal/stem damage | Very strong. Soft contact is the main advantage. |
| Holding stem bundles | Good. Lower damage risk than rigid parallel grippers. |
| In-hand manipulation | Low. It will not finely rotate flowers inside the hand. |
| Tool use | Limited. Robotiq or other industrial grippers are better for cutters/tools. |
| VLA data collection | Feasible if end-effector actions are logged through the arm control stack. |
| Customization | Medium. Commercial ecosystem is less hackable than LEAP or open-source hands. |
Recommended role: first end-effector candidate for actually holding flowers without damage.
Main caveat: not suitable if the research target is high-DoF finger action learning.
Adoption Judgment
OnRobot Soft Gripper is a practical match for OpenArm, xArm, UR, and Franka-style cells when the first goals are holding stem bundles, maintaining flower orientation, and fixing wrapping paper. In early bouquet-making experiments, a compliant gripper may deliver useful results faster than an expensive dexterous hand.
