Feedback from the Field (Trident Kickstarter Update #27)

Original post : December 12, 2017

Hello everyone,

We’re continuing to ship Tridents out to the first batch of beta users. So far, the feedback has been positive, and we’re getting some incredible footage and stories.

If you’ve missed our posts on social media, you may have missed this awesome video we got back from a Trident diving with sea lions near the Farallon Islands.

Another community member filmed some educational programming in Australia, and (with permission from the producer) we have a clip from that here:

We’ve also gotten some great feedback from some early beta users on social media such as this post from one of our community members on Facebook.

As we continue to gather feedback, we’re growing more confident in the production process. There are already a few process and design changes we're making based on what we've learned from the beta program so far. For example, we noticed that one of the pins on our tether connector was oxidizing when left wet after high numbers of saltwater dives due to how it was attached to our internal electronics. The fix for this was fairly straightforward and we’ve already instituted the necessary changes in our motherboard, but we’re happy we’ve been doing beta testing to find these types of issues early. Production and shipping will continue to steadily scale from here.

Trident Controller

Since the beginning, we've fielded questions about the best device to use for controlling Trident, and many users indicated they'd like a dedicated controller for the system. We heard these requests loud and clear, and we've made it happen. We’ve vetted a custom handheld console that we feel is optimal in many ways for making deployments easy and effective. There are many Android phones and tablets that work very well for controlling the vehicle, especially when paired with external joysticks that allow for tactile control, but if you want a controller with everything built into one device, the system we’re recommending is a great way to go.

Feedback from the Field (Trident Kickstarter Update #27)The OpenROV Trident Controller

You can pre-order the new Trident Controller directly from our store. It comes with OpenROV Cockpit pre-installed, has a great battery life (even with the screen constantly on), and also features high-sensitivity joysticks that allow for very precise control of the vehicle. One element of the controller we’re particularly excited about is a mini HDMI output port - so you can easily display your dive on a much larger screen or FPV goggles.

Accessory Platform Design

Now that we have locked down Trident’s design and are in production, we’d like to empower more people to get involved with building their own accessories for Trident. To help with that, we’ve published a STEP file for the outer profile of Trident on Github. This model includes the mounting hole pattern located on the bottom of Trident, which should be useful for anyone who’d like to attach external devices to the vehicle. We’ll also publish more about the interface between these devices and Trident’s onboard WiFi for communications shortly.

Of course, we’re always interested in what accessories people would like to see available for their Trident, so if there are specific payloads that you think OpenROV should look into, please feel free to suggest those here!

We’re really excited to have finally reached this step, and will continue sharing feedback and information from the beta program with you. We expect to complete the beta phase in January, and will begin fulfilling orders as our production line scales up. Stay tuned for more information about this in the next month.

Thank you very much!

Could you also include how to run Cockpit on a standalone RPi3 on my desktop for Payload interface development? Expand on what @Bob_Ellis did in “Having trouble getting started with Raspberry Pi openROV” such that the RPi3 Cockpit will run with:

  • eth0 - The wired tether connection to the PC
  • wlan0 - The Trident WiFi AP for the Payload communication
  • Debugging capable
  • Wetty included



Hi Eric, Two questions: is the controller waterproof, and if so does it work with an OpenROV 2.8?


Tudo o que precisamos é de conhecimentoDiferença entre hotel, hostel,
pousada e resort


What is shortly in this case? This information is important if the community should try to assist OpenROV to develop accessories like the gripper!


Any news on the Trident wifi comms interface for accessories?


Asked that recently and reply was later this year.


Topher, did you get a reply from Eric? I am interested in the same two things.


The third question on my mind is it says “bright” but how bright? Can we know the brightness factor? Use of screens in full sunlight is still a major issue in my operation where there is not a lot of workspace ( 3 m rib).


Hey guys,

Sorry I missed this thread before!

@topher Unfortunately the controller is not waterproof. It was designed as a gaming controller, and we’ve worked with the company to put our software, etc on it, but it still needs cooling fans and things like that which prevent it from being made that way. It doesn’t have an Ethernet jack built in, so if you were to try to use it with the 2.8, you’d need to attach your topside to a wireless router. Additionally, I haven’t tried using the version of Chrome that comes with the controller to log into Cockpit so I’m not sure if that would work. I’ll try some experiments and get back to you when I can.

@Kaare and @cmcp You’ve probably already seen the update post we made last month about this, but the overall message is that we’re working on bringing in more SW staff to help move this forward. The payload stuff has gone slow while we focus on making the rest of our software more stable.

@Robert_Cummins See above!

@achiffings That’s also something we’d really like to address. The screen on our existing controller is about the same brightness as a regular phone or tablet, so if you’re in direct sunlight you’ll need some sort of a shade. Some people have been using clip-on visors which seem to work well, and the controller also has an external mini-HDMI jack that you could use to plug in a set of FPV goggles that take HDMI. We’re searching for the most elegant solution to this, and would love to hear what things work the best for everyone.

I’m glad to be talking to you guys about this stuff!
