✨ Features

• 🔌 LOBOT LX Protocol Driver — Full implementation of the LX serial bus servo protocol
• 🤖 High-Level Robot API — Joint-level control with direction/offset mapping
• 🎬 Motion Teaching — Record, save, and playback robot movements with variable speed
• 🧠 OpenClaw Integration — Skill adapter for AI agent → robot control
• 🛠️ CLI Tools — robotclaw-scan for diagnostics, robotclaw-teach for interactive teaching
• ⚡ Thread-Safe — All serial operations protected by mutex locks

📦 Installation

pip install robotclaw

For development:

pip install robotclaw[dev]

🚀 Quick Start

Basic Servo Control

from robotclaw import ServoBus

# Connect to servo bus
bus = ServoBus()
bus.connect("COM3", baudrate=115200)

# Move servo ID=1 to position 500 in 1 second
bus.move(servo_id=1, position=500, time_ms=1000)

# Read current position
pos = bus.read_position(servo_id=1)
print(f"Position: {pos}")

bus.disconnect()

High-Level Robot Control

from robotclaw import Robot, DEFAULT_CONFIG

with Robot(config=DEFAULT_CONFIG, port="COM3") as robot:
    # All joints to home position
    robot.go_home(time_ms=2000)

    # Move a single joint
    robot.set_joint("left_hip_pitch", position=350, time_ms=500)

    # Read all joint positions
    positions = robot.get_positions()
    print(positions)

Motion Teaching & Playback

from robotclaw import Robot, DEFAULT_CONFIG
from robotclaw.recorder import MotionRecorder, MotionPlayer

with Robot(config=DEFAULT_CONFIG, port="COM3") as robot:
    # Record a motion
    recorder = MotionRecorder(robot)
    recorder.start_recording("wave_hand")

    robot.unload_all()          # Let user pose the robot
    input("Press Enter to capture frame 1...")
    recorder.capture_frame()

    input("Press Enter to capture frame 2...")
    recorder.capture_frame()

    clip = recorder.finish_recording()
    recorder.save(clip, "motions/wave_hand.json")

    # Play it back at 1.5x speed
    robot.load_all()
    player = MotionPlayer(robot)
    player.play(clip, speed=1.5)

CLI Tools

# Scan for connected servos
robotclaw-scan --port COM3

# Interactive motion teaching
robotclaw-teach --port COM3

🧠 OpenClaw Integration

RobotClaw ships with a built-in OpenClaw skill that allows AI agents to control the robot through natural language commands:

You: "让机器人回到初始位置"
AI:  → robot.go_home(2000) ✅

You: "播放走路动作，2倍速"
AI:  → player.play(walk_clip, speed=2.0) ✅

You: "检查所有舵机的电压"
AI:  → robot.scan() → 报告电压状态 ✅
