RobotClaw — Robot Control Skill

Control physical LOBOT LX bus servo robots through this skill. Bridges the digital AI world with the physical robot world.

Capabilities

Movement

• go_home — Move all joints to neutral home position
• set_joint — Set a single joint to a target position (0-1000)
• set_joints — Set multiple joints simultaneously
• unload_all — Disable torque on all servos (free movement)
• load_all — Enable torque on all servos

Status

• scan_status — Scan all servos and report: online/offline, position, voltage, temperature
• get_positions — Read current positions of all joints

Motion Recording & Playback

• record_start — Begin recording a motion sequence
• record_capture — Capture current joint positions as a keyframe
• record_finish — Finish recording and save to file
• play_motion — Play a recorded motion file at variable speed
• list_motions — List all saved motion files

Usage Examples

from robotclaw.openclaw_skill import OpenClawSkill

skill = OpenClawSkill(port="COM3")
skill.connect()

# Move to home
skill.execute("go_home", time_ms=2000)

# Check servo status
result = skill.execute("scan_status")

# Move a single joint
skill.execute("set_joint", name="left_knee", position=300, time_ms=500)

# Play a recorded motion
skill.execute("play_motion", motion_name="walk_cycle", speed=1.5)

skill.disconnect()

Safety Notes

• Always scan servos before commanding movements
• Use unload_all before manually posing the robot
• Monitor voltage — below 6000mV indicates low battery
• Monitor temperature — above 65°C indicates overheating
