Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# UNIHIKER Expansion Motor Control

Use this skill to control motors on a DFRobot UNIHIKER Expansion board (SKU: DFR1216). Chinese name is 行空板扩展板.

Run exactly one script with `lua_run_script`.

If `lua_run_script` returns an error, report that error directly to the user.
Do not retry with changed arguments in the same turn unless the user explicitly asks.

## Tool Call Inputs

Stop all motors:

```json
{"path":"{CUR_SKILL_DIR}/scripts/set_motor.lua","args":{"stop_all":true}}
```

Drive motor1 forward:

```json
{"path":"{CUR_SKILL_DIR}/scripts/set_motor.lua","args":{"period_12":255,"duty":{"m1_a":255,"m1_b":0}}}
```

Drive motor1 reverse:

```json
{"path":"{CUR_SKILL_DIR}/scripts/set_motor.lua","args":{"period_12":255,"duty":{"m1_a":0,"m1_b":255}}}
```

Drive four motors with mixed duty values:

```json
{"path":"{CUR_SKILL_DIR}/scripts/set_motor.lua","args":{"period_12":255,"period_34":255,"duty":{"m1_a":255,"m1_b":0,"m2_a":0,"m2_b":255,"m3_a":50,"m3_b":0,"m4_a":0,"m4_b":50}}}
```

Drive motor1 forward for 2 seconds, then auto stop:

```json
{"path":"{CUR_SKILL_DIR}/scripts/set_motor.lua","args":{"period_12":255,"auto_stop_ms":2000,"duty":{"m1_a":255,"m1_b":0}}}
```

How to install

The exact contents, by fingerprint

mdr add espressif/esp-claw-skills-lab/unihiker_expansion_motor_control@sha256:a3b11863b75b2908

The line at the top of this page pins the label git:20261014.4631425, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
