DC Motor Controller Serves Mobile Robots
Directly driving up to 120 A on each channel at up to 60 V, Roboteq’s AX2860 dual-channel DC motor controller functions in Automatic Guided Vehicles (AGV), Underwater Remote Operated Vehicles (ROVs), and mobile robots for exploration, hazardous material handling, and military and surveillance applications. The 9” × 5.5” × 1.6” device accepts commands from standard R/C radio for remote controlled robot applications, analog joystick, or RS232 interface. The unit can design fully- or semi-autonomous robots by connecting it to single board computers, wireless modems, or WiFi adapters via a serial port. The controller's two channels can be operated independently or combined to set the direction and rotation of a vehicle by coordinating the motors on each side. The AX2860 includes inputs for two quadrature encoders up to 250 kHz, four limit switches, and intelligent current sensing and controlling. Pricing is $720 with cable and PC-based configuration software.
