Boe-Bot Speed

uberness

Hi! I'm new to robotics and was wondering if there is anyway to make the Boe-Bot faster. I got the Boe-Bot robot kit.


Thanks!!

What do you mean by faster? The BoeBot is pretty zippy normally. It might help to use a 5 cell battery (5 x AA NiMH cells with the 5th cell sitting in a single cell holder over the rear wheel / ball. Make sure your program, whatever it may be, uses the full range of servo control pulse timing. The servo speed goes up as the pulse width gets further from 1.5ms (PULSOUT <pin>,750) which is the stop point. Less than 1.5ms goes in one direction and greater than 1.5ms goes in the other direction. Most servos will stop responding to pulses shorter than 0.5ms or longer than 2.5ms.

If you really do want something that goes faster, you will need to use DC motors rather than servos and use a motor controller designed for that. You'll probably need a larger power source.

You could replace the servos with higher performance ones. You would most likely have to modify said servos for continuous rotation.

Here's an example http://www.junun.org/MarkIII/Info.jsp?item=90
