  8. phil says:

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

    • Laurens says:

      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 says:

        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.

        • Laurens says:

          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????????????
