When designing Voyager II, the user control scenario is the main concern of ROV MAKER. Many ROV manufacturers have their own controller, since it is the main method of controlling the vehicle. ROV MAKER decided to use Notebook (NB)/Tablet, which has windows or Linux, as the controller of Voyager II. Notebooks and tablets are mature consumer products in terms of CPU performance, battery capacity, size or even price. In the past 30 years, software for notebook has developed by leaps and bounds, which can be seen not only in applications on windows /Iinux platform but also in cloud technology. Using NB as the controller of Voyager II helps users to write their program to control the vehicle and easily use cloud technology such as FB LIVE and Cloud storage.
Voyager II adopts WebRTC as the video transmission protocol. WebRTC is a kind of video conference protocol based on UDP/IP. It is especially useful when users connect the reel by WIFI. In this way, video won’t delay when WIFI signal is poor. On Voyager II, Janus Gateway is integrated for WebRTC Implement.
Given the above-mentioned software framework, the software development for Voyager II is based on the following issues.
With the above design guidelines in mind, ROV MAKER has implemented many functions for Voyager II. we are planning to open-source the Voyager II software so other experts will be able to implement their own features on Voyager II.
The following features have been implemented on Voyager II.
- Real time video based on WebRTC, which is implemented by Janus Gateway
- Software driver of 8250 IMU/MS5837-30B depth sensor/IST 8310 eCompass
- Control UI (HTML/CSS/JS)
- Factory Test Mode to calibrate/adjust ROV
- Software upgrade
- Depth-Control based on PID algorithm
- Heading-Control based on PID algorithm
- 720P video recording
- Navigation Logging
- Control ROV by touch Panel
