wow i think this is the

wow i think this is the first solar powered robot on LMR, iirc

so no controller at all… cool!

Btw, i saw you’re italian…
Btw, i saw you’re italian… I’ve always said it, italians do it better :slight_smile: All your robots are quite original and interesting.

Good write-up!

What is the voltage/amperage
What is the voltage/amperage you are seeing from those 2 cells indoors? I have future plans for a solar robot and I have been looking at cells.

** those are two solarbotic**

those are two solarbotic SCC3733

rated 6.7V , 15mA

I love the use of the logic

I love the use of the logic chip as a control mechanism. This is a nice change to all of the uProcs that we all use.

Great work and can’t wait to see more.

EDIT: I did a bit of searching since I was damn curious about how the logic behind this worked and found an article on the sb board that goes into a similar design using the 74hc240 chip.

This helped me to understand a bit more of how the chip was utilized. Again, I have to say, great work on this design noise0. :slight_smile:

I think this will help others in utilizing solar power in their bots.

nice job, can you make it
nice job, can you make it follow a black line instead of a white one?

This is such an awesome
This is such an awesome little bot, way cool noise0!
