Requirements

I would like to explore rather deep and cold places (see Exploration section). The temperature of the water in Baltic Sea is 1–22°C.

Interesting wrecks are at 50–80m.
I assume that the robot should work in the following environment:

1. Maximum depth: 100m
2. Minimum temperature: 0°C

The main problem will be the pressure 10bar at 100m.

Equipment

1. ATmega32 control unit
2. high sensitivity B/W camera
3. color camcorder
4. Pan and Tilt unit for B/W camera
5. 4W halogen lamp
6. LED lamp
7. Digital compass Devantech CMPS03
8. Grabber
9. Accumulator 12V
10. 3 DC thrusters
11. RS485 interface
12. 2 temperature sensors DS18B20
13. 2 leak sensors
14. pressure sensor
15. laptop + joystick + video capture card + control software
16. Cable 100m
