Leave a comment if you build one – let’s see how many pointless machines we can build together!

    The downloaded program does not work the same way that the video shows. Is there some thing done differently in the program? Phil

    • The one in the video is the same program as the one found on this page.

      Exactly what doesn’t work in the same way?

      • Phil

        I modified the power level to 15 from 5 and -10. It works much better now. These are the last program blocks in the forever loop.

        • I see. These values probably depend on battery level. I guess my batteries were fully charged when I filmed this.

          I limited the speed to protect the motors.

    English: My Useless machine keeps glitching the motor moves slowly maybe because the force is to strong for the motor????????????

    Nederlands: Mijn nutteloze machine maakt foutjes de motor beweegt langzaam misschien doordat de kracht die hij moet gebruiken te groot is????????????
