Gripper — Robot Gripper Reference

Quick-reference skill for gripper types, force calculations, actuator selection, and end-effector design.

When to Use

  • Selecting a gripper type for a robot application
  • Calculating required gripping force for a payload
  • Choosing between pneumatic, electric, and vacuum grippers
  • Designing custom jaw geometry for specific parts
  • Troubleshooting grip failures in production

Commands

intro

scripts/script.sh intro

Gripper fundamentals — types, actuation methods, key specifications.

types

scripts/script.sh types

Gripper types: parallel, angular, three-jaw, vacuum, magnetic, soft, adaptive.

force

scripts/script.sh force

Grip force calculation — formulas, safety factors, friction coefficients.

pneumatic

scripts/script.sh pneumatic

Pneumatic grippers — cylinders, valves, air prep, circuit design.

electric

scripts/script.sh electric

Electric grippers — servo, stepper, advantages over pneumatic.

vacuum

scripts/script.sh vacuum

Vacuum grippers — suction cups, venturi generators, cup selection.

applications

scripts/script.sh applications

Gripper applications by industry: automotive, electronics, food, pharma.

Usage Guidance
This skill appears to be a self-contained reference implemented as a local bash script that prints engineering guidance and formulas. Before installing or executing: (1) review the entire scripts/script.sh (the provided content was truncated in the listing) to confirm there are no hidden network calls, file writes, or command substitutions later in the file; (2) run the script in a sandbox or isolated environment if you want to be extra cautious; (3) if you set GRIPPER_DIR, point it to a directory you control (it’s only for local data storage per the docs). If you see any curl/wget, base64, eval, or unexpected subprocess calls in the remainder of the script, treat it as suspicious and stop. Otherwise the skill is coherent with its stated purpose.
Capability Analysis
Type: OpenClaw Skill Name: gripper Version: 1.0.0 The 'gripper' skill is a purely informational reference tool for robotics engineering, providing data on gripper types, force calculations, and industrial applications. The shell script (scripts/script.sh) only outputs static text via heredocs and contains no network calls, file system modifications, or suspicious execution logic.
Capability Assessment
✓ Purpose & Capability
Name/description (robot gripper reference) matches the runtime instructions and the included scripts which implement subcommands for types, force calculations, pneumatic/electric/vacuum guidance and checklists. There are no unrelated credentials, binaries, or install steps.
✓ Instruction Scope
SKILL.md instructs the agent to run local commands (scripts/script.sh <command>) that produce reference text. The provided script functions only print documentation and formulas; there are no instructions to read unrelated system files, collect environment secrets, or send data externally in the visible portion.
✓ Install Mechanism
No install spec — instruction-only usage with a bundled shell script. No downloads, package managers, or archive extraction are declared. The script is executed locally from the skill bundle.
✓ Credentials
The skill declares an optional GRIPPER_DIR for local data storage but requires no environment variables or credentials. The script content shown does not access or exfiltrate secrets or external services.
✓ Persistence & Privilege
always is false and the skill does not request persistent elevated privileges or modify other skill/system configs. It runs locally with normal agent invocation.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install gripper
  3. After installation, invoke the skill by name or use /gripper
  4. Provide required inputs per the skill's parameter spec and get structured output
