Dynamixel_motor_cont library {#mainpage}
Description
This driver offers a c++ wrapper to control a dynamixel servo. This driver provides a set of functions to:
- Configure the servo with an XML file.
- Download the current configuration to a XML file.
- Move the servo to a desired position.
- Move the servo to a desired position relative to the current position.
- Move the servo on torque mode.
- Get any feedback that the servo offers.
Installation
- Add the labrobotica repository if it is not already added:
Run the commands on add repository and add key from labrobotica_how_to installation
- Install the package:
sudo apt update && sudo apt install iri-dynamixel-motor-cont-dev
Important information
To use this driver is necessary to unload the ftdi_sio module, so the device is detected as a serial-usb device. This can be achieved with the following command
sudo rmmod ftdi_sio
or executing the following script:
unbind_ftdi_udev.sh -s <serial_number>

Dependencies
This package requires of the following system libraries and packages
- cmake, a cross-platform build system.
- doxygen and graphviz to generate the documentation.
- XSD to enable XML support.
- stdc++.
Under linux all of these utilities are available in ready-to-use packages.
Under MacOS most of the packages are available via fink
This package also requires of the following IRI libraries:
- iriutils, a set of basic tools.
- comm, a set of drivers for standard communication devices.
- dynamixel, a driver for dynamixel communication protocol.
Compilation and installation from source
Clone this repository and create a build folder inside:
mkdir build
Inside the build folder execute the following commands:
cmake ..
The default build mode is DEBUG. That is, objects and executables include debug information.
The RELEASE build mode optimizes for speed. To build in this mode execute instead
cmake .. -DCMAKE_BUILD_TYPE=RELEASE
The release mode will be kept until next time cmake is executed.
make -j $(nproc)
In case no errors are reported, the generated libraries (if any) will be located at the lib folder and the executables (if any) will be located at the bin folder.
In order to be able to use the library, it it necessary to copy it into the system. To do that, execute
make install
as root and the shared libraries will be copied to /usr/local/lib/iri/dynamixel_motor_cont directory and the header files will be copied to /usr/local/include/iri/dynamixel_motor_cont dierctory. If the support for XML file is enabled, all the necessary files will be copied to /usr/local/include/iri/dynamixel_motor_cont/xml. At this point, the library may be used by any user.
To remove the library from the system, exceute
make uninstall
as root, and all the associated files will be removed from the system.
To generate the documentation execute the following command:
make doc
How to use it
To use this library in an other library or application, in the CMakeLists.txt file, first it is necessary to locate if the library has been installed or not using the following command
FIND_PACKAGE(dynamixel_motor_cont)
In the case that the package is present, it is necessary to add the header files directory to the include directory path by using
INCLUDE_DIRECTORIES(${dynamixel_motor_cont_INCLUDE_DIRS})
and it is also necessary to link with the desired libraries by using the following command
TARGET_LINK_LIBRARIES(<executable name> ${dynamixel_motor_cont_LIBRARIES})
Examples
There are several examples that show how to use the different classes.
