Highlights

  • Control modes: MIT, POS_VEL, VEL, FORCE_POS
  • Typical motor types: 3507, 4310, 4340, 6006, 8006, 8009, 10010/L
  • Unified CLI: damiao scan, send-cmd-*, register tools, and damiao gui
  • Python API for multi-motor control with continuous feedback polling

Installation

pip install damiao-motor

Requirements: Linux + CAN interface (socketcan on can0, etc.). Set CAN bitrate to match your motor before running commands.

Quick start

Safety: these examples can move hardware. Secure the motor and keep clear of moving parts.

python examples/example.py

Edit examples/example.py to set motor_id, feedback_id, motor_type, and channel.

from damiao_motor import DaMiaoController

controller = DaMiaoController(channel="can0", bustype="socketcan")
motor = controller.add_motor(motor_id=0x01, feedback_id=0x00, motor_type="4340")

controller.enable_all()
motor.ensure_control_mode("MIT")
motor.send_cmd_mit(
    target_position=1.0,
    target_velocity=0.0,
    stiffness=20.0,
    damping=0.5,
    feedforward_torque=0.0,
)

state = motor.get_states()
print(state["pos"], state["vel"], state["torq"])
controller.shutdown()

Control laws

MIT mode (impedance control)

MIT mode control law

T_ref  = Kp * (p_des - theta_m) + Kd * (v_des - dtheta_m) + tau_ff
iq_ref = T_ref / K_T
id_ref = 0

CLI commands

All damiao subcommands require --motor-type (example: 4340).

Command Purpose
damiao scan --motor-type 4340 Scan bus for motors
damiao send-cmd-mit --motor-type 4340 --id 1 MIT command
damiao send-cmd-pos-vel --motor-type 4340 --id 1 POS_VEL command
damiao send-cmd-vel --motor-type 4340 --id 1 VEL command
damiao send-cmd-force-pos --motor-type 4340 --id 1 FORCE_POS command
damiao set-zero-command --motor-type 4340 --id 1 Zero hold command
damiao set-zero-position --motor-type 4340 --id 1 Set current position to zero
damiao set-can-timeout --motor-type 4340 --id 1 --timeout-ms 1000 Set CAN timeout (reg 9)
damiao set-motor-id / damiao set-feedback-id Change IDs (reg 8 / reg 7)
