Nasa Datanauts Water Cooler Chat: Evolutionary Robots for Space Exploration

  1. 1. MODULAR ROBOTIC SYSTEMS Reem Alattas Technology Transformer Twitter: @ReemTechFit
  2. 2. Agenda • Introduction • Modularity • Self-Assembly • Self-Reconfiguration • Self-Repair • Self-Reproduction • Evolutionary Robots • Printable Robots • Automatic Manufacturing
  3. 3. Introduction • The goal is to create systems: • Versatile • Robust • Low cost
  4. 4. Modularity • Modular robots are composed of various units or modules. • Each module involves actuators, sensors, computational, and communicational capabilities. • Modularity allows robots for self-assembly, self- reconfiguration, and self-repair.
  5. 5. Self-Assembly • Constructing complex multi-unit system using simple units. • Perform tasks in remote environments.
  6. 6. Self-Reconfiguration • Allows robots of metamorphosis, which in turn makes them capable of performing different sorts of kinematics. • Classes: • Lattice • Chain • Mobile
  7. 7. Self-Repair • Allows a robot to replace damaged modules with functional ones in order to continue with the task at hand.
  8. 8. Self-Reproduction • Allows robots to reproduce themselves from an infinite supply of parts using simple rules. • If the resulting system is an exact replica of the original, the system is called a self-replicator.

  13. 13. Telecubes – Suh et al., 2002
  14. 14. M-TRAN – Murata et al., 2002
  15. 15. Evolutionary Robotics • Evolutionary Robotics is a method for the automatic creation of autonomous robots. • Inspired by the Darwinian principle of selective reproduction of the fittest captured by evolutionary algorithms. Zykov et al. 2004
  16. 16. Printable Robots • 3-D printing, are becoming increasingly accessible. • 3D Printing allows fabrication of low cost, capable, agile, functional 3-D robots; such as Origami robots. Onal et al., 2014
  17. 17. Automatic Manufacturing • Combines evolutionary computation and additive fabrication. Lipson and Pollack., 2000
  18. 18. Conclusion • In this presentation, we have presented a comprehensive survey of modular robots that were created to meet three main goals, versatility, robustness, and low cost.
