How to Build a Quadruped Robot - NO MATH! -- Episode 538


 

What is better than a wheeled robot? One with legs! But usually when building Hexapods and Quadruped robots, you need to deal with a lot of complicated math and inverse kinematics! Clem ventures out to make a quadruped robot without having to do complicated math!

  •   Cool robot.  My vote is to make it walk smoother.  Since it seems to move one leg at a time, you could use one more servo to move a weighted horizontal wheel to move the center of balance away from the articulating leg.  The robot balances on the three non-moving legs and the fourth one goes where it is supposed to.  Continue rotating the weight to be opposite the articulating leg.  You may need to alternate rotation from time to time.  My gut says that it will wander left/right depending on the direction of spin of the weight.

    yes that would be a quite different approach to the conventional ways of moving them (usually lots of math to shift the servos incremental during each movement)
    could be interesting to explore this.
