What is BASV?

BASV is our new friday afternoon project (or spare evening/weekend hours). We want to create an Autonomous Surface Vehicle, so BASV stands for BerkelaarMRT Autonomous Surface Vehicle. In fact it can be seen as a robot-sailboat. On this blog you can find our success (failures?) of this project.

Remote controlled test

Yes, finally. After some major updates we were ready for some real life testing. 

First major thing we changed is the hull. The blue hull had some terrible sailing properties making it very difficult to steer. Also the stability was a real issue. To fix this we decided to use something what is commonly available: wind surf board. Difficult to sink, nice stability and easy to maneuver.

Production Skin

After the preliminary wing assembly it is time to coat the foam with a glass fibre skin.

Production Foam

Most of the foam parts will be milled with the big portal milling machine of Roberto Guido. The small flaps are produced on the milling machine of Science Centre Delft.

For the BASV a pcb is designed to handle all the low level stuff (ADC, PWM RC servo pulsing, power measuring). This board uses a STM32F103ZET6 microcontroller and has a connector for a Raspberry Pi. The raspberry Pi can handle the navigation, collision avoidance using maps, logging and internet connection.

Rib production

For the wing extra wooden ribs are placed to distribute the generated wind forces on the mast. To produce these ribs, they are first drawn in Alibre, exported as step, imported into the CAM software and finally the generated NC code is processed by USBCNC in the Science Centre Delft Milling machine

Wing design

The wing has a length of 2 meter with a chord of 0.55 meters. Giving a surface area of 1.1 m2
