Enables easy mobile robot automisation

Thanks to the simple and uncluttered nature of the mobile robot architecture, designers of robotic solutions gain more freedom to be creative The engineering effort to develop a safety compliant mobile robot is drastically reduced and can cut development costs by a factor of five; additionally the absence of bulky components offers complete freedom for the robot layout and shape.

Safety integrated and reliability requirements

Each SWD wheel is equipped with a certified safety controller that processes information from the robot's safety sensors to prevent unsafe movements. The built-in operational compliance to ISO 3691-4 (driverless truck standard) means safety features within the wheel include STO (Safety Torque Off), SLS (Safe Limited Speed), SMS (Safe Maximum Speed), SBC (Safe Brake Control) and SDI (Safe Direction Control) and direct compatibility with all SIL2/PLd safety laser scanners, such as the IDEC SE2L series. The drives can be easily chained together to provide multi-wheel or multi-axis systems capable of moving several tons. SWD drives feature standard CANopen CiA/DS 402 interfaces for motor control, and safety loops ready to connect to the safety sensors.

Integrator expectations

All the above safety features are pre-configured withing the SWD control and safety routines, which are usually complex and costly to develop, therefore the SWD solution provides much faster and cheaper development time to the user or integrator. Of course, individual adjustments to suit the specific application can be carried out through a number of SWD support and configuration tools. The SWD family are all configurable and provided with full drivers for both ROS and ROS2 (Robot Operating System) instruction sets, giving freedom to the developer.

Scalable technology

The minimum footprint of the series facilitates customised solutions. You can choose from the SWDCore (gear motor), the SWD125 (125mm diameter wheel) or the SWD150 (150mm diameter wheel). Each drive is sealed to IP66 (electronic housing) and available with various gear ratios, ensuring appropriate torque is available to move the required load. Applications for the SWD®Core include pallet shuttles, conveyors, lifts and mobile robots. Whereas the SWD125 and SWD150 can be deployed on applications such as logistic robots, mobile platforms, AGVs and AMRs with maximum speeds from 0.5 to 3 m/s, depending on the transferable load and the gearing used with the SWD)
