Project Guidelines
Your oceanic exploration team has just discovered an underwater seabed littered with golden riches. The loot lays
1 meter bellow the water and it’s in the interest of everyone to collect as much gold as possible.
The problem is the water is home to a vicious breed of piranhas (don’t place your hands into the water). You and
your team will have to build a ROUV (Remotely Operated Underwater Vehicle that can accomplish the following
tasks:





Achieve neutrally buoyancy
Surface and dive into the water
Survive the duration of the operation
Collect gold!!!
Dance (For bonus marks)
Your supplies are limited and your budget is under $50. You will need to work out a budget plan and create a
design that caters to your list of materials. The ROUV design has to be certified and approved by the Marine
Safety Publications (that’d be your teacher).
You’ll be running against the clock as another team of treasure hunters is after your precious…
Your precious!!!
You have until May 23, 20XX to complete your ROUV.
Key Components of a ROUV (Word-Picture Activity)
Electrical Aspects of an ROUV
Safety Content to Cover:
 Electrical Shock Hazard
 Water’s interaction w/ Electronics
 Short Circuiting
Procedures
Basic Concepts
The primary function of the electronics is to drive the motors, in a logical manner, based upon the response to
user’s feedback. This will consist of two circuits:
A. Primary Circuit – The User Controller
Students will need to be able to operate the ROUV while it’s under the water without physically interacting with it.
In order to do that the team must devise a controller that can drive the motors while it’s under the water. A tether
controlled ROUV is recommended. You are welcome to explore radio frequency based operation; be aware of how
the radio waves degrade as it interacts with the water (an antenna may resolve this issue).
B. Secondary Circuit – The Motor Driver
This circuit will interact with the response of the primary circuit and drive the motors in a logical manner. I’d refer
to the H-bridge circuit as a starting point (the Electronics – R students should be proficient with this concept).
There are three main motors that’ll be utilized in the ROUV. One motor will be designated for depth control; the
other two will control the steering and directing of the ROUV.
Schematic Diagram
Your first task will be to design a schematic diagram for the controller and the motor driver. Sketch out the
diagrams on the sheets provided for your team. Be sure to factor in:
•
•
•
•
Space, Dimensions and line weights of the copper tracings
Parts and Materials
Costs (no need to “Pimp yo ROUV”)
Labour Time
Your diagram needs to be approved by an instructor to ensure it meets the safety and functionality standards.
Eagle Design
Once your diagram’s been approved, you may proceed to designing it on Eagle. I’ve allocated a section in the
library specifically for the parts that’ll be used for our ROUVs (search with the keyword “ROUV”). Once you’ve
designed the electronics circuit, you may print it out on the “special” printer next to my office.
PCB Etching and Soldering
You’ll want to briefly review the basics of PCB etching and soldering from your previous notes.
