Hi all,

I am excited to announce Blue Trail Engineering’s new SER-20XX series of underwater servos which are depth-rated to 200 meters and are optionally available as a low-cost kit.

We currently have three models:

SER-2010, $395: 29.0 kgf-cm of torque with a default travel range of ± 70 degrees. Cobalt 3-pin bulkhead connector included. Sold fully assembled and tested.

SER-2020, $495: 34.0 kgf-cm of torque with a default travel range of ± 230 degrees, but programmable for up to ± 3.5 full turns of rotation with position control or continuous rotation with speed control. Brushless motor and magnetic encoder. Cobalt 3-pin bulkhead connector included. Sold fully assembled and tested.

SER-2000, $215: Low-cost kit option that allows users to select and install their own standard-sized R/C servo inside the enclosure – including PWM, CAN, or serial servos – as well as their choice of either a Cobalt bulkhead connector or an inexpensive penetrator. The SER-2000 is shown below unassembled and then assembled with a Blue Robotics WetLink Penetrator:

Hi @damonblue,

Always exciting to see advancements and refinements in underwater technologies, and reasonably priced depth-rated servos are seemingly few and far between.

Thanks for sharing! :slight_smile:

Nice work, @damonblue! These look great. I particularly like the DIY option with the SER-2000. That’s very cool!

What, typically, servos will fit inside this enclosure ?

Hi Øystein,

We know that these ones fit:

-Hitec D625MW, D645MW, D930SW, D940TW, D945TW, D950TW, D954SW, D955TW, DB961WP, MDB961WP-CAN, HSB-9360TH, HSB-9370TH, HSB-9380TH, HSB-9465SH, HSB-9475SH, HSB-9485SH, HSR-M9382TH

-GoBilda (all models)

I also have used some KST servos with a little bit of modification.

Other ones may fit as well. If you have one that you want to use, let me know and I can make a model of it and put it into my CAD assembly to see if it fits. Of course, this would require a drawing of the servo with dimensions (which most, but not all, manufacturers provide).
