How fast is a Rambot?

Alright, alright...

We've all heard that the Rambots are fast this year. From the sightings of a flying robot over New England to a robot who can catch it's own tail... you guys keep touting how fast this creature is.

Let's hear the facts. Answer these three questions and you'll tell us just how fast the Rambot '01 is:

What ratio are you running?

What is your wheel size?

How much does your robot weigh?

There are other questions, but these are the three most important. We assume that you are running in high gear (at least) on the drill motors.

To answer your question...

Yes, speed will be very important this year. There will be some robots who can go across the field in under 5 seconds, probably... but, they will also have some problems. Robot controlability is one thing that you gotta deal with, along with tripping the breakers after 20 seconds of running. Also, if you wanna do any turning, breakers will trip quickly.

The fastest robot I saw last year was team 188's (Woburn Robotics) 'bot at the Great Lakes Regional. They could get across the field in under 5 seconds, I think. They decided to gear down (slow down) for Nationals to be able to better control their robot. They had a 3:1 ratio on the drill motors in high gear, and they had 7 or 8" dia. wheels (if I remeber correctly... I don't want to mis-speak their design).

Buzz (175) also had a darn fast robot, but not quite as fast as 188's at Great Lakes. There are probably others, but these two stick out.

As for us... we're trying to get some speed, but with tank treads. Looks OK so far.
