Laboratory work and risk analysis
Laboratory work for this project will be mainly performed at AIRLab/Lambrate. It will include significant amounts of mechanical work as well as of electrical and electronic activity. Potentially risky activities are the following:
- Use of mechanical tools. Standard safety measures described in Safety norms will be followed.
- Use of soldering iron. Standard safety measures described in Safety norms will be followed.
- Use of high-voltage circuits. Special gloves and a current limiter will be used.
- Robot testing. Standard safety measures described in Safety norms will be followed.

Preliminary part design
The design of the body has evolved into the current shape through many development steps, in response to the varying specifications of the on-board electronics, to changes in the manufacturing process of the hull, and for a better approach to the hydrostatic balance problem.
The first two images below represents the early proposed mostly flat design, and a step of the manufacturing of a "master" hull component in a modelling clay. The third image shows a simple prototype made of polyurethane foam, tethered to the tank for power supply. It can be noted the original configuration of the tail components, which were mounted in a horizontal fin arrangement with two parallel actuators.
