Manual mode now receives angular velocity (degrees/s) via 0xA6 frame instead of
absolute angle reference. The firmware integrates velocity * dt into gimbal angle ref.
Motors are no longer auto-enabled at DMMotorInit — they stay disabled until a mode
switch out of DEBUG. Extract ROBOT_CMD_DELAY macro to replace magic number.
Fix "volity" typo → "velocity" and update docs/protocol comments accordingly.
- Add DEBUG mode (parallel to AUTO/MANUAL) for real-time PID parameter tuning
- New 0xA8 debug frame: 12 floats for vision/motor angle PID tuning params
- DMMotorSetMode: send zero-velocity before disable, clear PID to prevent jumps
- motor_enable topic: pub from robot_cmd, sub in gimbal, controls motor on/off
- motor_pid topic: pub from robot_cmd, sub in gimbal, updates motor angle PID
- Rename DM motor enums (DM_CMD_ENABLE_MODE/DISABLE_MODE, DM_Motor_Ctrl_Mode_e)
- SwitchToAuto/Manual: re-enable motors when switching back from DEBUG mode
- Static-allocate enable_msg/pid_tune in GimbalTask to avoid stack churn
- Add docs/host_comm_guide.md with Python Tkinter tuning GUI example
- Remove ARCHITECTURE.md
- Remove RC_ctrl_t and RemoteControlInit from robot_cmd.c
- Delete GIMBAL_ZERO_FORCE, gimbal_mode_e, Robot_Status_e from robot_def.h
- Remove EmergencyHandler and robot_state from robot_cmd.c
- Remove emergency commands from master_machine.h
- Remove remote_control and can_comm from CMakeLists.txt
