Presentation

In order to understand the use of the DCM, we need an overview of all the devices in the robot.

Electronics architecture:

../../../_images/dcm_electronic_arch.png

Device and subDevice definitions

Devices and subdevices are abstract definitions of objects used by the DCM.

  • Devices are subdevice controllers. The DCM communicates with them. They are mainly electronic boards in the robot, with their microcontroller. Each device is defined by a bus type and an address on this bus. It also has an unique name and a type.
  • A subDevice is mainly an actuator or a sensor controlled by a device. A subdevice is defined by its device, a subdevice type, and a subdevice number. This number is used because there is often more than one subdevice of the same type controlled by the one same device (for example a board with 3 LEDs). It starts at 1 (not 0) and increments. Each subdevice has a unique name (different from the Device one). This name is used for the communication with the upper level.

Both devices and subDevices have a series of keys with a unique value (usually a float, but it could be int, boolean or string) for each of the keys. Keys are for example “Value” (the main value), “Min”, “Max”, “Gain”, “Offset”, “Error”... There are some mandatory keys for devices and subdevices, but there could be many others, depending on the subDevice or the Device type.

If you add a prefix with the subDevice or Device name and the specific key name, you’ll have the string name of the subDevice key directly stored in ALMemory or the string name that you can send to the DCM for actuator change.

LED example:

“Face/Led/Red/Right/0Deg/Actuator”: This is the name of one of the LED actuator, the red LED near the right eyes at 0 angle.

This LED has a main value key named “Value”, this is a float from 0.0 (no light) to 1.0 (full light).

If you add the prefix, that is for subDevice :”Device/SubDeviceList/”, you have the complete key name: “Device/SubDeviceList/Face/Led/Red/Right/0Deg/Actuator/Value”

In ALMemory this is the key name that you can use to get the current LED value.

You can also use this name to send a timed-command value to the DCM for this actuator (for this precise use, the prefix is not mandatory).

Joint sensor example:

“LShoulderPitch/Position/Sensor”: This is the name of one of the joint angle sensor (Left shoulder pitch).

This joint has a main value key named “Value”, this is a float that is the angle in radian.

If you add the prefix, that is for subDevice :”Device/SubDeviceList/”, you have the complete key name: “Device/SubDeviceList/LShoulderPitch/Position/Sensor/Value”

In ALMemory this is the key name that you can use to get the current joint position value.

The joint sensor has also other key like “SensorType” ( “Device/SubDeviceList/LShoulderPitch/Position/Sensor/SensorType”). This is a configuration key that describes the kind of sensor for this joint, used then by motorboard. It’s not a good idea to change it!

You’ll see in next chapters the Device and subDevices names and all their possible keys.

The upper level usually communicates through the DCM with subdevices names (sensors / actuators) and seldom with devices names. But you can get useful information from devices (specific errors, ACK / NACK...).

Note

This scheme is a virtual point of view. Hardware buses are not shown.

List of communication bus

Here is the list of possible communication buses for devices:

  • MotherBoard A virtual bus for devices in the motherboard.
  • MotherBoardI2C I2C bus into the head
  • Chest A virtual bus for devices in the chest.
  • ChestI2C I2C bus into the robot body.
  • RS485Down RS485 bus for all boards in legs.
  • RS485Up RS485 bus for all boards in arms/neck.
  • LeftHandI2C Not implemented
  • RightHandI2C Not implemented

This is only useful if you want to understand the preference (configuration) file.

Type of device

Here is the list of possible devices:

  • MotherBoard The main CPU board in the head with the Geode processor.
  • ChestBoard The chest board with the ARM processor.
  • MotorBoard All motor board in the robot that control joints, except for foot and hand. They are specific.
  • MotorBoardHand Motor board for the hands. Right now strictly equivalent to MotorBoard.
  • MotorBoardFoot Motor board for the foots. Since the first released version of NAO, these boards do not manage motors anymore.
  • TouchBoard The board with capacitive sensors at the top of the head.
  • FaceBoard The board around the eyes of the robot, with LEDs and IR.
  • USBoard The board with the ultrasonic sensors.
  • InertialSensor The board with the accelerometer / gyrometer sensors.
  • EarLeds The board that controls LEDs in both ears.
  • Battery The board inside the battery.

This is only useful if you want to understand the preference (configuration) file.

Type of subdevice

Here is the list of possible subdevices:

  • Actuators

    • Joint: a Joint is the actuator that allows you to control the angle of one robot joint.

    • JointHardness: a jointHardness is an actuator that controls the percentage of the total power sent to the motor to control the joint. It’s 0% at the beginning and 100% at normal use (the value is from 0.0 to 1.0). Use this to have smooth increase/decrease of joint control.

      Hardness is defined as stiffness in motion.

    • Led: a basic LED (one color) where you can control the value from 0 to 100% (0.0 to 1.0).

    • Power: not implemented

    • Charge: not implemented

    • UsSend: an actuator that allows you to send an ultrasonic wave, waiting for the sensor result.

  • Sensors

    • JointPosition: the sensor value for the angle position of one robot joint.
    • Current: the electric current for one motor of a specific joint.
    • FSR: the weight on the FSR sensor (or on all the foot)
    • CenterOfPressure: The position of the force applied on one foot.
    • Touch: state of capacitive proximity switch (press = 1.0 or release = 0.0)
    • ChestState: not implemented
    • USReceived: the ultrasonic distance sensor result. Received after a wave is sent with the UsSend actuator.
    • Accelerometer: the result of one accelerometer axis (acceleration).
    • Gyrometer: the result of one gyrometer axis (rotation speed).
    • Angle: an angle of the robot, returned by the inertial board.
    • Temperature: temperature result for each motor (simulation) or the battery (sensor).
    • Switch: switch state (press = 0.0 or release = 1.0) for chest button or foot bumpers.
    • Battery: the battery state sensor (mainly charge).

List of devices

This is all device name/type/busNumber on the robot. They are mainly electronic boards.

../../../_images/dcm_devices.png

Note

The HeadBoard and the Battery can have the same address as they are not on the same bus.

Note

New Sanyo battery has I2C adress 52.

Joint names

Here is the list of all joint names (from the motion module documentation).

These names are used for all joints subDevices. A motorBoard controls one or two joints.

../../../_images/hardware_jointname.jpg

List of subDevices

Here is the list of all the subDevices of the robot.

The number is the subDevice Number. This is not useful, unless you want to understand the preference (configuration) file.

In ALMemory, the name of these subDevices are prefixed by “Device/SubDeviceList/”.

Note

This is only the subDevice list. For all keys and meaning of values, see next chapters.
