Controller with USB
Roboteq’s SDC2130 (30V) / SDC2150 (50V) controller is
designed to convert commands received from an RC radio,
Analog Joystick, wireless modem, PC (via RS232 or USB) or
microcomputer into high voltage and high current output for
driving one or two DC motors. Fitting a very compact 70x70mm
board, and designed for maximal ease-of-use, it is delivered
with all necessary cables and hardware, and is ready to use in
minutes.
The controller features a high-performance 32-bit microcom-
puter and quadrature encoder inputs to perform advanced
motion control algorithms in Open Loop or Close Loop (Speed
or Position) modes. The SDC2130/SDC2150 features several
Analog, Pulse and Digital I/Os which can be remapped as com-
mand or feedback inputs, limit switches, or many other func-
tions.
For mobile robot applications, the controller’s two motor chan-
nels can either be operated independently or mixed to set the
direction and rotation of a vehicle by coordinating the motion of
each motor. Numerous safety features are incorporated into the
controller to ensure reliable and safe operation. The controller's
operation can be extensively automated and customized using
Basic Language user programs. The controller can be repro-
grammed in the field with the latest features by downloading
new operating software from Roboteq.
