Let's Make Robots!

Snapper

 
Nothing much

UPDATE 2:

Project has ended and robot is disassembled. link

UPDATE 1:

Since i changed from PIC to Atmega, I remade this bot's whole brain. H-bridges and motor controllers were a headache so I changed motors to servos. Also now i have new power source, 5x AA NiMh regulated to 5V for electronics. Hmm. New pictures soon.

 

-- Original --

First bot what is entirely my built and has sensors what are connected to brain. Now it just moves its gripper open and close and does other preprogrammed activities. First i tried to use prototypeing board (green one with premade tracks) but everything failed so i moved to self made breadboard. I know that it is a mess of wires, but it is really handy. All parts are from eBay & Farnell.

 

 It has such name because all it does is snaps.

 

Bigger batteries are for motors & servos. 9V for electronics and sensors. There is a voltage regulator hidden in that heatsink.

 

I'm using L298N to drive motors. For some unknown reasons servos sometimes go grazy if i motors run, and i think motors are too big for this robot. I'm thinking of changing over to 2X 9g servos. It could use tiny omniwheel or roller to tip of tail.

 

Idea is that it moves around and if it finds anything it can use its tail servo to tilt whole body + arm. By doing this it can scan the height of thngs and crab things from different angles. If it crabs something it pulls prey to its lair.

 

(Soon: more sensors, activity and videos.)

I knew it existed I just thought it was more central or easter Europe. Too many new countries over there.
If there is one awesome thing about this website it is the fact that we all get to learn geography! I had no idea where Estonia even was. Actually, I really didn't even know it was even a country! I thought it was one of those places from back in history. Too cool. Welcome.
:D it doesn't surprice me. Like some years ago it was Soviet Russia. Good part is that i have big box full of russian electronics.
If you got balls, you can use it to snap them..............
I like it, it looks like it's evolved from a pile of junk, looks cool.
