AX2550

Dual Channel,

Forward/Reverse

Digital Speed Controller

for Remote Controlled and

Computer Guided Robotic Vehicles

oboteq’s AX2550 controller is designed to con-

vert commands received from a R/C radio,

Analog Joystick, wireless modem, or microcomputer

into high voltage and high current output for driving

one or two DC motors. Designed for maximal ease-

of-use by professional and hobbyists alike, it is deliv-

ered with all necessary cables and hardware and is

ready to use in minutes.

The controller's two channels can either be operated

independently or mixed to set the direction and rota-

tion of a vehicle by coordinating the motion on each

side of the vehicle. The motors may be operated in

open or closed loop speed mode. Using low-cost

position sensors, they may also be set to operate as

heavy-duty position servos.

The AX2550 can be reprogrammed in the field with

the latest features by downloading new operating

software from Roboteq’s web site. Numerous safety

features are incorporated into the controller to

ensure reliable and safe operation in the most

demanding mobile robotic vehicle applications.

give your robot muscle with brains Roboteq’s AX2550 controller is designed to fit a wide range of mobile robotic vehicle applications.
PAGE 3
multiple input modes The AX2550’s multiple command input modes - R/C Radio Pulse Width, Serial Port or Analog - make it uniquely interfaceable to all types of microcontrollers, remote control radios, or other command devices. tes eR teS R/C Radio Mode R/C Pulses R/C Radio is the most popular, simplest and least expensive method to build and operate a remote controlled robot.
PAGE 4
multiple command modes The AX2550 may be connected to two motors which will react to commands received on two input channels. Using these two channel inputs, the motors can be commanded independently or in a combined fashion to accommodate the most common drive and steering methods in robotic vehicles. Independent Speed Commands In this mode, each of the two motors is commanded independently of the other. This operating mode is best suited for generic motor control applications.
PAGE 5
multiple motion modes For each channel, the AX2550 supports multiple motion control modes: Open Loop Speed mode In this mode, the controller delivers an amount of power proportional to the command information. The actual motor speed is not measured. This mode is adequate for most applications where the operator maintains a visual contact with the robot. Tachometer Speed Feedback Closed Loop Speed mode In this mode, an analog tachometer measures the actual motor speed.
PAGE 6
simple and fail-safe operation For all its sophistication, the AX2550 is very simple to install and operate. Its many configuration options are programmed using only two switches and a LED display on the controller front panel. The controller may also be connected to a PC for setting configuration parameters using a convenient Graphical User Interface.

sturdy and lightweight construction 3.00" (76 mm) 4.00" (102 mm) 5.50" (140 mm) The AX2550 is built into a extruded aluminum case which also serves as a heat sink for its electronics. The large fin area ensures sufficient heat dissipation for operation without a fan in most applications. 0.25" (6.3 mm) Mounting brackets on each end are provided for durable assembly of the controller onto any robot chassis. Optional shock mount absorbers may be added for use in the most brutal environment. 7.
