A ready-made drive subsystem instead of months of R&D

Roboteq is a motor controller that manages motors in mobile robots and vehicles: it controls torque, speed, braking, and direction. It typically serves as the low-level control layer between the onboard computer and the drivetrain.

Typical applications include AMR/AGV, UGV, autonomous carts, logistics platforms, and special-purpose electric vehicles. It fits where stable traction and predictable drivetrain behavior are needed in 24/7 duty cycles.

Start with the DC bus voltage (e.g., 24V/48V/60V), continuous current, and peak current required by the motor and load profile. In practice, include margin for acceleration, inclines, and start-up torque.

Depending on the series, controllers can support BLDC motors (with or without Hall sensors) and brushed DC motors. The drive technology affects smoothness, efficiency, and feedback requirements.

For applications that need stable speed and repeatability, closed-loop control with encoders or Hall sensors is used. It improves load compensation and yields more predictable acceleration and braking.

In mobile robotics the most common are CAN bus, RS232/RS485, and USB for configuration and diagnostics. Interface choice affects the control architecture (MCU/IPC/PLC) and real-time integration.

Yes. In industrial architectures the drive controller often communicates with a PLC over serial interfaces or CAN, with process logic implemented in the higher layer. Define data exchange cycles and fault handling strategies.

Many mobile applications use dual-channel configurations to control left and right drives in differential-drive or skid-steer platforms. This simplifies wiring and enables consistent ramps and current limits.

Typically you configure acceleration/braking ramps, current limits, control mode (torque/speed), and regulator parameters for feedback operation. Good tuning reduces jerks and improves traction.

During regenerative braking, energy can raise the DC bus voltage (regen overvoltage), especially with high inertia. Projects use energy absorption strategies such as a braking resistor (shunt) and appropriate protection thresholds.

Beyond drive configuration, critical elements include emergency stop (E-Stop), undervoltage/overvoltage monitoring, current protection, and correct wiring/grounding architecture. This is the foundation for safe operation in industrial environments.

Account for cooling conditions, ambient temperature, duty cycle, and current margin versus load. Stable thermals are one of the main drivers of drive controller reliability.

For maintenance, key signals are current, voltage, temperature, fault codes, and states. Integrating drive telemetry enables faster root cause analysis and reduces fleet downtime.

In selected use cases, local logic on the controller handles simple sequences and input reactions. This is useful in edge-control architectures where some decisions must occur without network latency.

Gather motor parameters, power supply voltage, target speeds and vehicle mass, gearbox type, payload mass, and required communication interfaces. This enables selection based on real peak currents and operating conditions.
