OnRobot Gecko Single Pad (SP) Gripper Review: Specs, Price and Applications
The OnRobot Gecko Single Pad (SP) gripper uses a dry adhesive inspired by gecko feet to pick flat, smooth objects. It is offered as SP1, SP3 and SP5, the number indicating the payload in kilograms.
No air supply or electronics are required, and the gripper leaves no marks. It handles perforated items such as circuit boards and shiny surfaces where vacuum struggles, and its compact single pad reaches into tight spaces. It is plug-and-play with leading small robots and cobots.
Quick Verdict
A unique gripper for flat, glossy or perforated parts. It removes compressed air from the cell and handles parts vacuum cannot hold.

Design and Operating Principle
Gecko adhesion relies on millions of microscopic fibres that create van der Waals forces when pressed onto a smooth surface. The pad sticks when preloaded against the part and releases when the fibres are peeled, which the gripper does mechanically.
Because there is no vacuum, perforated parts such as circuit boards or mesh do not leak, and shiny surfaces do not need cleaning before gripping. The absence of air also removes noise and compressor energy.
Adhesion depends on surface smoothness and cleanliness; rough, dusty or oily surfaces reduce holding force, and pads should be cleaned periodically.
Integration and Selection
Choose SP1, SP3 or SP5 by part weight and accelerations, and test the actual surface finish. Program a short pressing move so the pad engages before lifting.
Plan pad cleaning and replacement intervals based on part cleanliness.

The Gecko SP suits cobot users handling flat, smooth or perforated parts without compressed air.
Price and Availability
Price: Request a quote. OnRobot prices the Gecko SP1 / SP3 / SP5 by size, options and quantity, so the final figure depends on the exact configuration. Budget for the complete tooling package, including fingers or adapters, mounting, air or electrical connections and commissioning time, rather than the module alone.
