An Arduino Based Quadruped Robot

Arduino-Based-Four-Legged-Robot

Sure, we see hexapods all the time at [HAD], but moving around with four legs can be more tricky kinematics-wise. This Instructable shows you how to make one out of balsa wood.

Although one might not think of balsa to make their robot out of [vexedpheonix] explains that this was chosen because it’s extremely light and easy to work with. Since he was trying to keep costs down, the cheapest servos available were used. These weren’t all that powerful, so the lighter the body the better! According to the included bill of materials, he was able to keep the entire robot build under $100.

According to the article, the hardest part was making four copies of the same leg. We might suggest using a CNC router, but building one would obviously add a huge layer of complication to the project!

Thanks for the tip on this one [SteveT]! Be sure to check out the video of this little robot waving one of it’s legs or trying to walk after the break!

  1. Glad to see that the writing on the introductions are back to normal. I was getting nervous.

  2. Too subtle?

    Always makes me smile and see prototyping in wood. To me this is the most obvious choice to use before spending time and money on fancy plastics or metal

  4. Nardella says:

    If I was trying to make it walk I would have it move only one leg at a time. At least until you work out a more complex gait.

  5. Keith says:

    Consider adding some rubber feet to the legs.

    Hey
    I have staretd the development of arduino based Quadruped robot for my college project.I initially started with the purchase of hardware like servo brackets,robot leg
    and i purchased it at a very cheap cost compared to others.I purchaesd robot parts form http://danuc.com/index.php?main_page=index&cPath=5&zenid=90cb06ec660ea0d127525d1cf4e45b49
    .I also bought the quadruped robot chasis for the same website http://danuc.com/index.php?main_page=index&cPath=3 .Its awesum and my full assembled robot is complete
    and it looks perfect.Now i want to start with the programming of the same robot using arduino.I want to know which dimensional measurements of the robot to feed to the IK program
    and if u can tell me according to your program which parameters i need to measure as per my chassis.If u show it in pictorial format i will be gratefu to u.

    Thanks
