Detailed assembly instructions are available for the Triggerfish kit, including video lessons, classroom activities, and many more topics here. You will need to register to access our lesson plans, however, registration is free.
The SeaMATE Triggerfish Kit is designed for 15 amps. Modifications that increase the ROV's overall amperage above 15 amps may require certain components to be modified as well. See the assembly instructions for additional information.

The Triggerfish is an easy to construct ROV kit that moves from a switchbox controller to analog joystick control of four motors. The Triggerfish ROV kit consists of a control system, wires to receive and deliver power, and thrusters (motors, propeller adapters, and propellers). A frame is not included in the kit, but frame materials can be purchased from your local hardware store.
The control system is housed inside a compact, Seahorse brand protective equipment case. Two joysticks make piloting the Triggerfish ROV easy and logical. Each joystick controls two motors, one joystick controlling forward/reverse and turning, the other joystick controlling up and down, and sideways movement. The joysticks and control boards on the Triggerfish allow speed control; nudging the joystick forward provides slow speed while pushing the joystick fully provides full-speed movement. The Triggerfish comes video ready (video system sold separately) with two video input channels and easy power out for monitors and cameras. A volt and ammeter along with multiple LED indicators display vehicle status and make the Triggerfish easy to troubleshoot. Modular connections mean that Triggerfish control boxes and vehicles are interchangeable.

Students will want to drive their Triggerfish ROV by utilizing the robot's sense of sight. Be sure to add the Triggerfish/Barracuda Video System Kit (TWO Cameras) to your order.
In addition to the ROV having vision forward, it will be important to utilize an additional camera to help the Triggerfish ROV see other peripheral ROV features to help the team achieve the challenges of the MATE ROV Competition.

A POWER SUPPLY is not included with this kit
The Angelfish kit does not come with a power source. You will need to provide a power source to power your vehicle. We offer three different solutions, depending on your budget and how you intend to use the ROV.
For a solution that never needs recharging, we recommend an AC to DC, 30 amp power supply that plugs into an AC outlet, and provides a constant source of 12 volt DC power that the ROV needs. This power supply can operate two Angelfish vehicles at once without issue.
SAFETY NOTE: Since this converter is being used near water, you must plug this converter into a Ground Fault Circuit Interrupter (GFCI) protected outlet or have a GFCI plug on the end of the converter. DO NOT PLUG THIS INTO A STANDARD WALL SOCKET WITHOUT GFCI PROTECTION.
We also recommend keeping the AC to DC converter in a splash proof container or case. A small plastic tub turned upside down will work to keep splashes off the power supply.
The 12V power supply with GFCI protected outlet is available here.
Power pack with Powerpole adapter:
Powerpacks are battery packs that will provide the power your ROV will need. Powerpacks are often kept in vehicles to jumpstart a dead battery. They will run down over time but can be recharged by plugging them into a wall socket. The length of time a power pack can run an ROV depends on the ROV's power demands. Here is an example of a jumpstarter power pack with a 12V socket (external link)
The power packs will need an adapter for the Powerpole connector to plug into. This adapter plugs into the 12V lighter outlet found on the power packs, and the Powerpoles from your ROV plug into the adapter.
12 volt Deep-Cycle Marine/RV car battery with alligator adapter:
Large lead acid batteries are another way to power the ROV. We recommend the Deep-Cycle Marine / RV battery, as they are designed to be run down and recharged many times (a standard 12-volt car battery is not designed for this). The battery should be able to run a Triggerfish ROV for 3 to 5 hours or you can run 3 ROVs at a time for about an hour. The battery will need to be recharged after that. To recharge a car type battery, you will need to purchase a charger.
The battery will also need an adapter for the Powerpole connectors from your ROV to plug into. This adapter has Alligator clips that connect to the battery posts on one end and has Powerpole connectors at the other end.
