McMaster Carr

McMaster Carr offers a great selection of industrial components and raw materials. We commonly source acrylic tube, O-rings, fasteners, adhesives, aluminum rods, machining tools, and valves from them. Their main attraction is a large inventory and one-day shipping.

Mechanical Vendor

Blue Robotics

Blue robotics is our main source for thrusters, penetrators, and depth sensor. They offer affordable and reliable marine thrusters, T100 and T200 series. Their watertight, single-use penetrator populates both of our electronic endcaps.

Mechanical Vendor


Sometimes we purchase acrylic tubes from eplastic because they have better selection. They also offer more types of plastics there.

Mechanical Vendor


Teledyne designs the impulse series, splash-proof, underwater electrical connectors. These “sub-conns” allow us to tether the robot underwater and supply shore power to it. If needed, email them for quotes.

Mechanical Vendor

Amazon / Small Parts

We use amazon to purchase 3D printer filaments to be used in SSL printers. Sometimes, tools like dial caliper, or COT parts like buoys are bought here.

Mechanical Vendor

Peifer Waterjetting

Peifer offers affordable water jetting services. The side panels of current robot were machined at Peifer.

Makerbot Innovation Center

We use the innovation center for most 3D print prototyping job. They charge $0.10 per gram and has more enough printer to ensure a quick turnout time. This means we can quickly print a placeholder and use it on robot before the actual part is fabricated.
