How to choose battery for Racing Drone

How to choose battery for Racing Drone Larger battery provides longer flight time. on the other hand It increases weight and thous decrease speed As the battery gets heavier, the increase in flight time becomes smaller. Eventually it will reaches a point where it just doesn’t gain any more flight time with bigger battery (even lose flight time). LiPo batteries (short for Lithium Polymer) are a type of rechargeable battery that is the battery of choice in the RC world . Chacteristic of Lipo Betteries RC LiPo batteries are light and can be made in any shape.

Anyone know about machine learning on Arduino?

I saw this code about Neural net on an Arduino here: http://robotics.hobbizine.com/arduinoann.html

and would like to know how I could apply it to my latest robot DuckBot so that it could figure out how get back on it's feet

on it's own instead of me having to code explcitely to do that. I have one sensor that currently says if angle of sensor indicates < 145 degrees then robot has fallen. It uses 3 servos to get back up on its feet.

Any ideas greatly appreciated.

Quadruped Sneak Peak!

In the Grapes of Wrath, there was a turtle that had a lot of symbolism, and in English class, you can basically do anything for the final project. So I thought, what the heck, I'll just play my strengths! Below is a rough CAD using 3d-printed parts and MG996R servos. Electronics are not really shown, shell is not missing (like there's a CAD of a salad bowl out there), and the head has been remodified to have a more "turtle" look. Photos of the final product coming soon.
