Head3 [project
suspended] |
|
A solar head constructed
with brass stock and shaft collars. This particular robot uses a variant
of the Wilf Rigter Solar Power Smart Head that was adapted to have two
separate degrees of freedom (it can track light both vertically and
horizontally). |

I have finished the circuitry for the
most part. The only things left to add are the solar cells (two of them)
and the power capacitor. I am very happy with how this project is coming
along. I used socket pins on many of the connections to allow for easy
disassembly of the robot. I am slowly moving towards completely modular
designs and this is a prime example. The circuit has been powered and
works, but it is really sensitive (too much so). It will be tuned in the
coming days. Enjoy!! |

Here are some preliminary pictures of my
newest project, a 2DOF head. So far I have finished the motor mounts and
the basic linkages. The motors are Escap gearmotors from Solarbotics and
are held together with a hand-made piece of copper. The linkages is made
of brass and held together with solder and nickel plated shaft collars
from my local hobby store. When completed it will have two solar cells
positioned on either side of the motors satellite style. One will face
the same direction as the head while the other will be permanently facing
upwards. I am still brainstorming on ideas for the base. I want a big
gear or block of brass to solder the supporting rod to (will replace the
Vice Grips in the first picture). |
