#New #Wheels and Slow motion video comparison of the Brute Force PID algorithm Vs the FSM DOC algorithm. Left side is the Brute Force robot with Vmax 255/255 at 11.1v (3s lipo) and 8 sensors and right side is the FSM DOC robot with Vmax 225/255 at 7.4v (2s lipo) and only 6 sensors. Notice how more elegant the motion of the FSM DOC is and how the front sensor stays longer on the actual line despite having 2 less sensors and a significantly smaller width. #unique #project #pid #control #theory #future #Gregoris #LineFollower #Fast #Robot #Custom #STEM #BuiltNotBought #MyBrainChild #I #Love #Arduino #Dedicated #Gregoris #ItoldYouIwouldDoIt #competition #imagine #instagood #art #beautiful #happy #instadaily #science #engineering

    What if you add camber on the back wheels?

  • @robotics.lab 2:06 PM Jan 5, 2019

    @hotwheelsatl You can’t add camber on such wide wheels, you will loose traction, plus there is no suspension system on a wheeled robot. As you can see I solved the drifting issues with software. This is also the purpose of this post, to show that by thinking out of the box and by putting some effort one can invent innovative ways to solve common issues.

    @gian_nos_ele What if you used narrow wheels that far out with camber?

  • @robotics.lab 7:51 AM Jan 6, 2019

    Max robot width can’t exceed 250mm. Using narrow wheels results in loss of traction, these motors run at 3000rpm. No amount of camber can give back the amount of traction lost by reducing the width of wheels. Hence the fix with the software. But I can try if someone donates a test robot vehicle
