Mobile Robotics

Definition of Mobile Robots

  • Robots with manipulators, navigation systems, and autonomous driving capabilities.

KUKA Mobile Robotics

  • Divided into two product groups:
    • KMP: KUKA Mobile Platforms
    • KMR: KUKA Mobile Robots

KUKA Mobile Platforms (KMP)

  • Two standard products:
    • KMP 200: Supports loads up to 200 kg
    • KMP 1500: Supports loads up to 1500 kg
  • Project-based applications can support loads from 3 tons to several hundred tons.

KUKA Mobile Robots (KMR)

  • Includes iiwa robots mounted on platforms.
  • Project-based applications include:
    • QUANTEC robots
    • KMR KR 60

Common Features of KMP and KMR

  • Vehicle Safety Functions:
    • Laser scanners for a surrounding area
    • Divides safety area into two zones:
      • Yellow Warning Zone: Speed reduction when entered.
      • Safety Field: Complete stop when entered.
  • Emergency Stop Buttons: For immediate stopping.
  • Audio and LED Signals: Indicate vehicle status.
  • Batteries: Lithium-ion, available in 4 or 8 hours running time, up to 5000 charging cycles.
  • Controller:
    • Manages both platform and robot (in KMR).
    • Configurable from one software/computer.
  • Navigation System: SLAM-based with laser scanners.
  • Fleet Management:
    • Flexible handling system.
    • Capable of manual operation with wireless controller.
  • Other Features:
    • OmniWheels for high flexibility and precision movements.
    • Lifting devices on board (KMP).

Navigation Systems in Mobile Robotics

  • Possible solutions include inductive guidance, optical guidance (rotating lasers and mirrors), magnetic grids, indoor GPS.
  • SLAM Navigation:
    • Mapping: Manual driving to create a map.
    • Path Creation: Defining paths and parameters.
    • Command: Higher system gives missions to vehicles.
    • Fleet Manager: Manages tasks and communicates with PLC/ERP/MES systems.
    • Cloud-connected for remote monitoring.

Benefits of Mobile Robotics

  • High flexibility and precision in movement.
  • Space saving in production layout due to omniWheels.

Practical Implementations and Events

  • Demonstrations at TechCenter in Augsburg and Gothenburg.
  • Possibility to arrange events at customer sites.
