The Bumpers
|
|
|
First version realized on 13 - 10 - 2007 |
|
|
|
They are done with 2mm diameter iron wire, covered with heat shrink tubing.
|
|
|
|
|
|
|
The collision avoidance system is divided in three different sections, in order to detect frontal and lateral bumps.
|
|
|
Each section acts on its own slotted optical switch. |
|
|
|
Mobile parts are installed on 20 x10 mm sized hinges.
They are fixed with plastic blocks, obtained by PVC bars.
All these parts are available in bricolage shops too.

After some tests outdoor or in higly illuminated environments, it was evident the need of a better light shield
