Let's Make Robots!

Solar Charger for my robot

I have placed several solar cells on the top cover of my robot, Shrödinger.

I noticed that for various reasons such as shadows falling on some cells, or one side being closer to a light, that the cells did not charge at the same rates. Solar batteries do not work well if they are allowed to backfeed the current from one to another. Consequently, I used diodes in each string of two to block this backfeeding.

Mini Robotic Ant Farm

I have started the build of the first Drone prototype for my little ant farm project. I plan on building around 4 Drones and a Builder.

 


1. The Drones:

Chassis:

The Drones will be as simple as possible, using TH components, as is hard to prototype with SMD. A double sided, plated holes prototyping board will be used as the chassis. The board is 38mm x 38mm and it can get smaller only if I use a smaller battery.
