Il RoboClaw è un driver per motori a spazzole che offre una corrente in modalità continuativa sino a 15A per canale e correnti di picco sino a 30A! Risulta essere un ottimo controller per motori DC di media potenza, indispensabile in tutti i progetti di robotica mobile!
The RoboClaw motor controllers from Orion Robotics can control a pair of brushed DC motors using serial, RC, or analog inputs. The integrated dual quadrature encoders make it easy to create a closed-loop speed control system, or analog feedback as position control. This version can supply a continuous 15A per channel (30A peak).
The RoboClaw from Orion Robotics (formerly Basic Micro) is an efficient, versatile, dual-channel synchronous regenerative motor controller. It can supply two brushed DC motors with 5 A, 15 A, 30 A, or 60A continuous (depending on the model) at voltages from 6 to 34 V, and it allows for peak currents up to twice the maximum continuous rating.
The RoboClaw features dual quadrature decoding capability. A built-in PID routine can be used for closed-loop speed control, maintaining motor speeds even if the load varies and to read from encoder pulses.
Several interface modes are supported by the RoboClaw: it can be controlled via TTL serial for use with an embedded system or a PC with a serial adapter, RC hobby servo pulses for use as an RC-controlled electronic speed control (ESC), or analog voltages for use with potentiometers or analog joysticks.
