I'm building this robotic snake , with 8 servo motors. Out of them , 2 are modified servos and they propel the snake forward ( they've been modified for 360 degrees rotation) and the remaining 6 servos are controlled by a microcontroller board for the coiling action of a snake.
Now my problem is that the snake is'nt able to move as fast as required (i.e the modified servos aren't able to rotate that fast).
How do I increase the forward motion of my snake? Do I add some more motors or do I replace the modified servos with some other motors?
Also, has anyone tried to build sucha bot before?
