Each board allows one of the LabPro's Digital ports to control both
a stepper motor and either a servo motor or a voltage-activated device
such as a light or buzzer. With two boards, the LabPro can
run a SAM robot.
A single board can also be used with the CBL2 to run a 1-dimensional
cart or a pointer. The board can also be modified with an alternative
phone jack to work with the original CBL. Because they each have just
one digital output port, this board is NOT appropriate for controlling
a multifunction robot from the
original
CBL
or CBL2.
This electronic circuit is very straight-forward and
reliable. Iit is an ideal choice for anyone who has access to
a LabPro and wants a
"work horse" robot for classroom use. It is less "intelligent" than
our EDE1200 board, however, and requires continuous
signals
from the LabPro, CBL or CBL2 to operate. (The EDE1200
board has on-board
memory and processing capabilities which enable it to continue operating
without continuous signals from the interface. It also has the ability
to control more servo motors and the EDE1200 board can be "daisy
chained.")
