3. Description
3.1. A toolkit for robot developers
The SWD® Starter Kit is made of combinable, modular devices for mobile robotics.
The SWD® Starter Kit introduces key technologies for mobile robots' development
•SWD® Safety Wheel Drive: the world’s first drive with embedded safe motion control
•Safety Laser Scanner: the smallest laser scanner for safety critical applications
•ROS Robot Operating System: the reference middleware for robotics

3.2. Integrated Safety
The SWD® Starter Kit provides the simplest AGV/AMR safety architecture ever:
•SWD integrates motor drivers
•Unique, fully certified safe motion features
•Safety encoder integrated into SWD
The robot architecture is therefore extremely simplified compared to conventional AGVs or AMRs:
✓Drives interfaced directly with safety laser scanners
✓Replaces safety encoders, PLCs, and motor drivers
