Niryo One - MATLAB interface
This repository contains resources of Niryo One Matlab Interface. This interface has some similar functions asNiryo One Studio This interface enables you to exchange data between ROS-Niryo One and Matlab. This interface connects Niryo-one to MATLAB to analyze differences between planned trajectory and executed trajectory. In this application, we can compare between the 2 differnet trajectories by ploting them as shown below.
this project connect to niryo one ros
list of Niryo One -MATLAB inetface functionality :
- Activate/ Disactivate learning Mode.
- Calibrate Motors .
- Request New Calibration.
- Send command to Niryo one.
- Plot planned and executed trajectory.
- Plot differences between planned trajectory and executed trajectory.
- Export/import Data.

- Display logs applications.
1.Install and Configure MATLAB-Ros Environment
1.1 Install MATLAB
MATLAB has several versions, If you dont have MATLAB installation file, try to get the newer version.The installer can be downloaded from here: MatlabDownload. N.B. MathWorks provides the licensed product, a trial version and a student version.
Install MATLAB in your PC and make sure to select robotic toolbox while installation.
After finishing the installation , launch MATLAB Command windowand make sure that the Robotic toolbox is installed by running :
1.2 Set up MATLAB environment
1.2.1 Install robotics System Toolbox
To install Robotics System Toolbox, Run this command in MATLAB command window:
Then Choose Robotics System Toolbox Interface for ROS Custom Messages and click install.
N.B. If you have MATLAB R2017a and earlier versions, you have to follow this Bug Reports
1.2.2 Create Custom Messages from ROS Package
You can follow this tutorial. In order to add niryo one msgs ,
- In windows , clone niryo one ros and note the folderpath.
- In Ubnutu, If you already install Niryo One ROS packages on your computer, you just have to note the folder path.
Now , in MATLAB command window run:
folderpath = your_folder_path
Follow steps 1 to 3 from the output of rosgenmsg:
- Edit javaclasspath.txt, add the following file locations as new lines, and save the file:
<your_folder_path>\jar\dynamixel_sdk-3.4.7.jar <your_folder_path>\matlab_gen\jar\mcp_can_rpi-1.0.0.jar <your_folder_path>\jar\niryo_one-1.1.0.jar [...] <your_folder_path>\matlab_gen\jar\niryo_one_rpi-1.1.0.jar <your_folder_path>\matlab_gen\jar\niryo_one_tools-1.1.0.jar <your_folder_path>\matlab_gen\jar\niryo_one_user_interface-1.1.0.jar
- Add the custom message folder to the MATLAB path by executing:
- Restart MATLAB and verify that you can use the custom messages. Type
Ensure that the output contains the generated custom message types.

1.2.3 Connect ROS-MATLAB to ROS robot as a master
- Find the name of your hostname In windows, open cmd window and type hostname (e.g. WINDOWSPC) In Raspberry Pi, type hostname -I (e.g. ROBOTPC)
-Look for IP_ address of robot and matlab computer, they should had the same mask 255.255.255.0 e.g.
192.168.65.82 % <ROBOTIP> 192.168.65.80 % <WINDOWSPCIP>
- Edit file "C:\Windows\system32\drivers\etc\hosts" in windows and "/etc/hosts" in Raspberry Pi by adding those two lines :
192.168.65.82 <ROBOTPC> 192.168.65.80 <WINDOWSPC>
Restart your computer
Turn off all the firewalls on Mtalab PC and Ubuntu PC
Set environment variables on your robot
export ROS_MASTER_URI=http://<ROBOTIP>:11311 export ROS_IP= <ROBOTIP>
Restart your robot
- try to ping both windows pc and the robot For more information:RosNetworkSetup on matlab window command
Pinging <ROBOTIP> with 32 bytes of data: Reply from <ROBOTIP>: bytes=32 time=6ms TTL=64 Reply from <ROBOTIP>: bytes=32 time=4ms TTL=64 Reply from <ROBOTIP>: bytes=32 time=4ms TTL=64 Reply from<ROBOTIP>: bytes=32 time=4ms TTL=64
- On MATLAB command window , set the environment variables for ROS:
N.B. the last step is not necessary , cause it s already in matlab code
2.Download the application
First download or clone the application file form here
3.Getting started with the application
- For your first connection : open niryo One Studio and follow the steps to connect Niryo one to the wifi network in order to connect your computer and your robot to the same network.
- Open Matlab_Gui file
- Click run
This will bring up the start screen
Put your in the first text box( its the same ip address you used to configure connection between robot and matlab-ros).
Put your in the first text box( its the same ip address you used to configure connection between robot and matlab-ros). Put your in the second text file ( the same you used in section 2.1.3) Click connect to Niryo one button to connect Matlab to your robot . wait few seconds until the connection is established. When the button turned to connected you can start commanding your robot.
Go to arm Command button
You can use Learning Mode button to activate /disactivate learning mode You can use calibrate Motors button to start calibrating motors.
- You can send command to your robot: Enter joints value and click Move joints ,you must see you robot move to the following command.
- In order to compare the planned and the executed trajectory ,enter joints value, press listen to trajectory button first, and then press Move joints button. The application will work for a few second before presenting you the results of trajectories on plot trajectory window. Choose the joint ( form joint 1 to joint 6) you want to plot and you will see a curve graph of the planned ,the real trajectory and the difference between them.
- If you want to export result, click export button , choose a location and a name of your text file. the trajectory will be saved in both a text and an excel file.
- You can import a saved trajectory data by clicking on import button and choosing an excel file.
- Click Hardware Status button to get updated hardware status.
- Click application logs button to see your history activities.
Thank you !
