to mark as completed Quadro_Pet
I wanted to make a 4 legged robot inspired by the way dogs walk. However i initially had no idea about robots or programming. Then one of my friends,Adrian introduced me to Arduino.
We ordered 4 tower pro servos from ebay and bought all the other items including the Arduino uno board locally.Since arduino has many libraries and has a much simpler form of C++, it was easier for us get hold of it. Once the servos arrived we tried to make a Quadruped with just 4 servos (tower pro sg90 ) however, it was an utter disaster. The gearing was plastic and they were stripped and the robot never moved and inch forward.
Then we ordered another 8 servos (Tower pro mg90s) that had metal gearing. They held up really well throughout our project and very much recommend it, To power the servos we used an external power supply which we initially plugged into a usb port.
We were worried about the portable power supply. when we found out about the rechargeable batteries that came with CDMA telephones of 4.2v. They were perfect for our arduino project.
Once, the codes for moving forward and back were done, we altered the code to make it work through a usb seriel port via the software puTTy. We assigned keys to each movement. We also connected a bluetooth module HC-06.
Currently we are working on the code to turn the robot left and right and using puTTy via the usb connection as of (16th May 2017).
