Control and command a DJI RoboMaster EP using Mental Commands fetched from EMOTIV's Cortex API. The description of the cortex, dji-robomaster and cortex-dji folders can be found by clicking on them.
As the EMOTIV Cortex API is a WebSocket server that uses the JSON-RPC protocol, any version of Python that supports websocket-client can be used. The description for it can be found here.
The latest version of Python (as of March 2021), 3.9.2 was used to write and test the code in the cortex folder. Python 3.9.2 can be downloaded here.
There are also prerequisites that need to be met before the Cortex API can be used, such as an EmotivID, License and Cortex App.
The attached code prints out the name of the mental command and the power of it when a subscription request is sent to Cortex. Other data such as the sessionId and time are not printed, and will need to be extracted from the data sample object if desired.
The Python.exe file needs to be for 64-bit installation and the version must be between 3.6.6 and 3.8.9. Otherwise, the DJI RoboMaster Python SDK cannot be properly used due to compatibility issues.
Instructions to set up the necessary programming environment can be found at DJI's RoboMaster Development Guide.
Python 3.8.8 was used to write and test the code in the dji_robomaster folder. This version of Python can be downloaded here.
The RoboMaster application also needs to be installed to allow the DJI RoboMaster EP to connect via Wi-Fi router mode using a QR code that will be generated in the application. It can be downloaded here.
To cater to the DJI RoboMaster Plaintext SDK, Python 3.8.8 was used to write and test the code. This version of Python can be downloaded here.
The requirements for both the Cortex API and DJI RoboMaster mentioned above must be met.
To utilise the code, the following values need to be found and replaced accordingly.
For the Cortex API, it will be:
- [clientId]
- [clientSecret]
For the DJI RoboMaster, it will be:
- [ip_address]
