FIRST (or “For Inspiration and Recognition of
Science and Technology”) had a strong presence at the
Faire this year. The international robotics competition
was founded in 1992 by Dean Kamen — the brilliant
inventor behind the Segway.
This year at Maker Faire, FIRST’s booth showcased
2011’s challenge called “Logo Motion.” The challenge
broke down like this:
• Three robots per team, two teams per match.
A variety of FIRST robots were on display, and
several teams were even allowing test drives.
STEER WINNING ROBOTS
Perform proportional speed, direction, and steering with only two Radio/Control channels for vehicles using two
separate brush-type electric motors mounted right and left
with our mixing RDFR dual speed control. Used in many
successful competitive robots. Single joystick operation: up
goes straight ahead, down is reverse. Pure right or left twirls
vehicle as motors turn opposite directions. In between stick
positions completely proportional. Plugs in like a servo to
your Futaba, JR, Hitec, or similar radio. Compatible with gyro
steering stabilization. Various volt and amp sizes available.
