AX3500
Dual Channel
Forward/Reverse
Digital Robot Controller
with Optical Encoder Inputs
2 x 60 SmartAmps
for Computer Guided and
Remote Controlled Robotic Vehicles
Roboteq’s AX3500 controller is a product family designed
Key Features
Benefits
to convert commands received from a R/C radio, Analog
Joystick, wireless modem, or microcomputer into high volt-
age and high current output for driving one or two DC
motors. Designed for maximal ease-of-use in OEM applica-
tions, it is delivered with all necessary cables and hardware
and is ready to use in minutes.
Dual MCU digital
design
Accurate, reliable, and fully programma-
ble operation. Advanced algorithms
R/C mode support
Connects directly to simple, low cost R/
C radios
RS232 Serial mode
support
Connects directly to computers for
autonomous operation or to wireless
modem for two-way remote control
The controller's two channels can either be operated inde-
pendently or mixed to set the direction and rotation of a
vehicle by coordinating the motion on each side of the vehi-
cle. 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.
Analog mode support
Optical encoder inputs
Connects directly to analog joystick
Stable speed regardless of load. Accu-
rate measurement of travelled distance
Built-in power drivers
for two motors
Supports all common robot drive meth-
ods
60A output per channel Gives robot strongest lifting or pushing
power
The AX3500 may be ordered in one of many assembly
options, depending whether optical encoder input is
needed and depending on the application’s power, number
of channels, and thermal requirements.
Programmable current
limitation
Protects controller, motors, wiring and
battery.
Open loop or closed
loop speed control
Low cost or higher accuracy speed con-
trol
The AX2550 can be reprogrammed in the field with the lat-
est features by downloading new operating software from
Roboteq’s web site. Numerous safety features are incorpo-
rated into the controller to ensure reliable and safe opera-
tion in the most demanding mobile robotic vehicle
applications.
Closed loop position
control
Create low cost, ultra-high torque
jumbo servos
Data Logging Output
Capture operating parameters in PC or
PDA for analysis
Built-in DC/DC con-
verter
Operates from a single 12V-40V battery
Field upgradable soft-
ware
Never obsolete. Add features via the
internet
