mechanism-design
Skill for mechanism kinematics, dynamics, and motion analysis
npx skills add a5c-ai/babysitter --skill mechanism-design --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Mechanism Design Skill ## Purpose The Mechanism Design skill provides capabilities for mechanism kinematics, dynamics, and motion analysis, enabling systematic design and optimization of mechanical motion systems. ## Capabilities - Linkage synthesis and analysis - Cam profile design - Gear train design and analysis - Kinematic simulation - Dynamic force analysis - Motion optimization - ADAMS/RecurDyn integration - Mechanism specification documentation ## Usage Guidelines ### Kinematic Analysis #### Degrees of Freedom ``` Gruebler's Equation (planar): DOF = 3(n-1) - 2j1 - j2 Where: n = number of links (including ground) j1 = number of full joints (pin, slider) j2 = number of half joints (cam, gear) DOF = 1: Constrained mechanism DOF = 0: Structure DOF < 0: Over-constrained ``` #### Common Mechanisms | Mechanism | Links | Joints | DOF | Application | |-----------|-------|--------|-----|-------------| | Four-bar | 4 | 4 pins | 1 | Motion generation | | Slider-crank | 4 | 3 pins + 1 slider | 1 | Reciprocating motion | | Scotch yoke | 4 | 2 pins + 2 sliders | 1 | Exact sinusoidal | | Quick return | 4 | 3 pins + 1 slider | 1 | Unequal stroke times | | Geneva | 2 | Cam joint | Intermitt

What does the mechanism-design skill do?
Skill for mechanism kinematics, dynamics, and motion analysis
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill mechanism-design --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
