GECKO GRIPPER V1.0

Product catalog summary

General Properties:
The Gecko Gripper is designed for handling various materials such as polished steel, acrylic glass, and sheet metal. It can handle a maximum payload of 6.5 kg (14.3 lb) with a safety factor of 2. The gripper requires a preload of 140 N for maximum adhesion and has a detachment time of 300 milliseconds. It can hold a workpiece even during a power loss. The pads have a change-out interval of 150,000 to 200,000 cycles for high preload and 200,000 to 250,000 cycles for low preload. Manual cleaning is done with isopropyl alcohol and a lint-free cloth, while robotic cleaning is performed using a cleaning station.

Sensors:
The gripper is equipped with an ultrasonic range sensor for pre-load sensing, with a range of 0 to 260 mm (10 inches) and an error margin of 7% to 2%. It has an IP classification of 42.

Operating Conditions:
The operating temperature ranges from 0°C to 50°C (32°F to 122°F). The gripper is most effective on smooth, low surface roughness substrates that are flat, stiff, and rigid.

Effectiveness on Different Materials:
The gripper's effectiveness varies with the material's stiffness and surface finish. For rigid materials with a mirror-like finish, a medium preload is required for a payload of 2 kg. For flexible materials, the effectiveness decreases, and higher preload may be necessary.

Preload and Payload Matrix:
The document provides a matrix showing the gripper's capability to pick up different materials with varying stiffness and roughness at three preload values: low (40N), medium (90N), and high (140N). The matrix indicates which materials can be easily picked up, which require caution, and which cannot be picked up.

Material Characteristics:
Stiffness and roughness are rated on a scale from 1 to 10, with examples provided for each level. For instance, a stiffness of 1 corresponds to flexible fabric, while a roughness of 1 corresponds to polished metal with an RMS value of 0.1 micron.
