Quattro is a quadruped that we developed that can do several things.

leg_init.inoQuattro's legs need to start at their "initial position". To do this run the servo motors with this program and then set the legs to their correct positions.ino - 456.00 bytes - 07/19/2017 at 13:53 |

Quattro_test.inoBetter run this on a cup as a support. Quatro should before it's gait.ino - 20.25 kB - 07/19/2017 at 13:53 |

quattro_ik_pr.inoThis is infact very complex. Developed with the mathematics from Inverse Kinematics Quattro can now do pushups!ino - 3.60 kB - 07/19/2017 at 13:53 |

quattro_add_feat.inoThis code is with the added on obstacle avoiding feature. Quattro with the ultrasonic sensor will navigate in an environment without knocking into objects.ino - 20.63 kB - 07/19/2017 at 13:53 |

Its been a year since we have been working on this project but it's finally complete. Quattro can now walk, see, avoid obstacles and even dance. She might look dangerous but remember she's non-lethal : )
That's it from us!
Today we tested Quattro on a cup, she worked rather well. Although when put on the ground she struggles a bit, I say we give her a bit more power...updates soon.
PS: wiring up this beast is a real mess!
A big thanks to our friend Suman Pal who really brought this project to life by developing the maths and then converting it to code.
After three months, of failure, after blood sweat and tear , Quattro has finally manifested herself in this Beauty. Very satisfied with the product. What about you guys?
Now the tough bit developing algorithms to make it walk!
We bought the small servo motors of Amazon which performed rather well.
The star of the show is definitely the Arduino Nano, because of its size and power. I'm off to making this beast!
We started this project in 2016 and after lots of modifications we have finally succeeded in a robust frame ready for laser cutting
Hi guys! Here's a spider robot that we had made for the 2016 science fair which was held at our school. Well, you can't technically call it a "spider robot" as spiders have 8 legs, but we atleast tried to make it look like a spider (or maybe spider like) . Our robot has four legs, so the correct term would be a quadruped. Well guys say hello to "Quattro", a non lethal, arduino quadruped!
Here is an instructable on how we made her, taking you through the building process, getting to the programming and finally admiring the robot come to life once its finally done :) . Watch the video to get an idea of what it will finally look like, the problems we encountered and how we solved it and improved it.
Before going to the next step please note that a laser cutter has been used in the making of this robot. A laser cutter can be avoided if you are very skillful with your hands, as precision is key to completing the project!
The robot has 4 legs, with 3 servo motors in each leg, which give the legs a freedom of three degrees. We use a simple gait to get the robot to walk which is known as the creep gait .
We used a creep gait as its one of the simplest, slowest and yet smoothest of all gaits. At first we just get the robot to walk forward, back, left, and right and then we add cooler features such as obstacle avoiding and Bluetooth control to take it to the next level.

I think you should give her a first name - Suzy. :-)
