endeffector

What This Skill Does

The endeffector skill for OpenClaw acts as a comprehensive knowledge repository and technical reference for robot end-of-arm tooling (EOAT). It provides structural data regarding ISO flange standards, Tool Center Point (TCP) calibration protocols, and payload management. Whether you are an engineer selecting a commercially available gripper or a designer creating custom vacuum fixtures, this skill offers command-line access to essential formulas and industry-standard best practices. It serves as an bridge between theoretical robot kinematics and the physical constraints of the tool interface, ensuring that robot configurations remain within safe load and geometric limits.

Installation

To integrate this skill into your local OpenClaw environment, execute the following command in your terminal:

clawhub install openclaw/skills/skills/bytesagain/endeffector

Once installed, you can configure the data directory by modifying the ENDEFFECTOR_DIR environment variable, which defaults to ~/.endeffector/. Ensure your shell has sufficient permissions to access the installation directory to allow for local caching of mounting standard data.

Use Cases

• Engineering Design: Determining the structural stiffness and cable routing requirements for a custom 3D-printed or machined end-effector.
• System Integration: Calculating the total moment of inertia for an arm equipped with a heavy pneumatic spindle and a complex multi-part workpiece.
• Maintenance: Troubleshooting TCP drift by executing standard 4-point or 6-point calibration scripts.
• Procurement: Evaluating compatibility between a specific robot wrist flange and a universal tool changer or vacuum generator.

Example Prompts

1. "OpenClaw, run the tcp calibration guide and show me the difference between the 4-point and 6-point methods for my arc welding torch."
2. "I'm designing a new gripper for a Fanuc arm; what are the ISO flange bolt pattern requirements I need to account for in my CAD model?"
3. "Calculate the payload for a 2kg vacuum tool holding a 0.5kg part; does this exceed the recommended safety limits for a collaborative robot?"

Tips & Limitations

This skill is primarily an information and reference agent. While it provides accurate industry standards and calculation methods, it does not perform physical hardware actuation. Always verify payload calculations against your specific robot manufacturer’s dynamic load charts, as this skill provides general guidance that may not account for non-linear acceleration or high-speed maneuvers.
