Configure Data Capture
Add the Data Management Service
To capture data from one or more robots, you must first add the Data Management Service:
On your robot’s Config page, navigate to the Services tab.
At the bottom of the page you can create a service. Choose
Data Managementas the type and specify a name for your Data Management Service, for example
On the panel that appears, you can manage the capturing and syncing functions individually and specify the interval and directory. If the capture frequency or the directory is not specified, the Data Management Service captures data at the default frequency every 0.1 minutes that is every 6 seconds in the default
If you change the directory for data capture only new data is stored in the new directory. Existing data remains in the directory where it was stored.
Click Save Config.
Configure Data Capture for Individual Components
Once you have added the data capture service, you can specify the data you want to capture at a component level. The following components support data capture:
- Movement Sensor (includes GPS)
To add data capture for a component, navigate to the Config tab of your robot’s page in the Viam app.
For each component you can capture data for, there is a
Data Capture Configuration section in its panel.
Add Method and then select the method type and the capture frequency.
Avoid configuring data capture to higher rates than your hardware can handle, as this leads to performance degradation.
Click Save Config at the bottom of the window.
Now your data will be saved locally on your robot to the directory specified in the Data Management Service.
For example, a camera has the options
NextPointCloud and a motor has the options
You may capture data from one or more component methods:
- To enable or disable data capture for a configured component or method, use the
- To change the frequency of data capture for a method, enter the number of measurements you wish to capture per second in the frequency field.
After adding configuration for the methods, click Save Config.
If you want to remove a capture method from the configuration, click the
Configure Data Capture for Remote Parts
Viam supports data capture from remote parts. For example, if you use a component that does not have a Linux operating system or that does not have enough storage or processing power, you can still process and capture the data from the component by adding it as a remote part.
Currently, you can only configure data capture from remote components by adding them to your JSON configuration.
To add them to your JSON configuration you must explicitly add the part’s
additional_params to the
data_manager service configuration in the
|The type tells your robot what the part is. For example, a board.|
|The model is a _colon-delimited-triplet that specifies the namespace, the type of the part, and the part itself.|
|The name specifies the fully qualified name of the part.|
|The additional parameters specify the data sources when you are using a board.|
To sync your captured data with the cloud, configure cloud sync.
