  1. 1. German Carro Fernandez* , Elio Sancristobal Ruiz, Sergio Martin Gutierrez, Manuel Castro Gil, Francisco Mur Perez Electrical and Computer Engineering Department Spanish University for Distance Education (UNED) Madrid, Spain
  2. 2. German Carro Fernandez germancf@ieee.org Flexibility of wireless technologies in learning in robotic laboratories • Introduction • Wireless Communication • Flexibility of wireless technologies in learning • Conclusions This contribution was solely written by students and/or doctoral candidates.
  3. 3. German Carro Fernandez germancf@ieee.org Flexibility of wireless technologies in learning in robotic laboratories Solution: Wireless Let’s go to see Why!
  4. 4. German Carro Fernandez germancf@ieee.org Objective: Reflects the importance that wireless may have in:  Safety: avoid unintentional injuries  Efficiency and productivity: avoid distractions  Costs: avoid unnecessary expenses  Autonomy: avoid depends on a wire length,… …in learning and e-learning process, as well as the motivation that this changes cause on the students Flexibility of wireless technologies in learning in robotic laboratories
  5. 5. German Carro Fernandez germancf@ieee.org Flexibility of wireless technologies in learning in robotic laboratories • Introduction • Wireless Communication • Flexibility of wireless technologies in learning • Conclusions
  6. 6. German Carro Fernandez germancf@ieee.org Today there are some alternatives on market…  IrDa port Communication:  Based on light rays moving in the infrared spectrum  Bidirectional at 4 Mbps and 1 meter  Common devices (TV remote controls)  WI-FI Communication:  802.11 Standard  Several wide band and up to 100 meters  Common in laptops Flexibility of wireless technologies in learning in robotic laboratories
  7. 7. German Carro Fernandez germancf@ieee.org  Bluetooth Communication:  Designed specifically for low power devices  720 kb/s (1 Mbps raw) and 10 meters  Common on any robotics kits (Lego)  NFC and tags Communication:  Short-range and high frequency  Up to 848 kbit/s and less than 10 cm  Any educational robots (Kibot) Flexibility of wireless technologies in learning in robotic laboratories
  8. 8. German Carro Fernandez germancf@ieee.org …the other side of the coin…  Security: The wireless communication systems are more vulnerable than traditional systems via cable or wires …the advantages  Security is enough for educational environments  Training should focus on learning to use a specific robotic equipment, where direct practice prevails against everything else Flexibility of wireless technologies in learning in robotic laboratories
  9. 9. German Carro Fernandez germancf@ieee.org Flexibility of wireless technologies in learning in robotic laboratories • Introduction • Wireless Communication • Flexibility of wireless technologies in learning • Conclusions
  10. 10. German Carro Fernandez germancf@ieee.org Installation and equipment costs in wireless learning environments  Selection and adaptation of environment in which it will be developed the learning  Wires:  Installation of rails to accommodate the wires  So many connectors as computers and robots to be used  Switches needed to try to save installation time  Adequate supervision and control cable lengths and pinched them  Wireless:  Decide the tool to use communication (Wi-Fi, Bluetooth, NFC, IrDA)  Install the respective receiver/transmitters on the PCs and robots  Less material, less hours for installation, etc. => Less costs on time and money Flexibility of wireless technologies in learning in robotic laboratories
  11. 11. German Carro Fernandez germancf@ieee.org Safe E-learning  Student interaction with equipment and tools on-line:  Wires:  Presence of a supervisor who avoids possible accidents  Limits the flexibility in the use of these systems  Reduce operating time depends on the availability of a third party to conduct the activity  Wireless:  Facilitate student interaction from remote terminals without physical presence in the classroom or lab environment  The only parameter to ensure will be a good wireless connection in place and, of course, a good Internet access Flexibility of wireless technologies in learning in robotic laboratories
  12. 12. German Carro Fernandez germancf@ieee.org Safe E-learning  On academic environment:  The student can anticipate possible experiments based on the study,  increasing their curiosity about the use of the robot to use,  or develop new uses for it, out of the face and tutoring of traditional classroom, or supplementing it  On industrial environment:  This type of remote communication can be the difference between a significant reduction of errors by the operator when working with a new team,  or avoid long hours of classroom training in place work that will result in a waste of time and decreasing in production Flexibility of wireless technologies in learning in robotic laboratories
  13. 13. German Carro Fernandez germancf@ieee.org Increased student motivation  Student interaction with equipment and tools:  Wires:  Discomfort of having to connect and disconnect a robot kit every time we have to load new software on it  Risks of unintentional injuries  Difficulties to work in group. People + Cables= Uncomfortable  Wireless:  Load of data with a single click. Agile feedback student-robot  Low risk  Comfortable to team working But wireless is not everything… Flexibility of wireless technologies in learning in robotic laboratories
  14. 14. German Carro Fernandez germancf@ieee.org Increased student motivation  Student interaction with software (other stone in front of motivation):  Specific software:  Must be easy to use and avoid agile feedback between student and robot  If needed, is better teaching its use on a specific course for avoid overcharge the student Customized Lab View Interface => Flexibility of wireless technologies in learning in robotic laboratories
  15. 15. German Carro Fernandez germancf@ieee.org Increased student motivation  Student interaction with software (other stone in front of motivation):  Commercial software (Robotic kits):  Usually is easy to manage  Focus the attention at robot and use the software as tool Commercial Lego Mindstorm Interface => Flexibility of wireless technologies in learning in robotic laboratories
  16. 16. German Carro Fernandez germancf@ieee.org Increased student motivation  The scary question: Was the student motivated?  Survey : If you want to know how the students felt the class, please, answer it to them!  Feedback: Even during the course. Every time is a good time to change if the next way is better  Look at them: Look the students, their way of work, their activities during the class, can give to us more information that any other tool Flexibility of wireless technologies in learning in robotic laboratories
  17. 17. German Carro Fernandez germancf@ieee.org Increasing autonomy of the robot  Wires:  Cables block the movement  Slow movement and, in many cases, prevents certain rotations or translations  The robot that can end up caught between them  Wireless:  The only limit: Wide range of communication (usually more length than cable length)  Can help test the robot, and handling, from a safe distance,  or through windows or rooms away from the main interface handling Flexibility of wireless technologies in learning in robotic laboratories
  18. 18. German Carro Fernandez germancf@ieee.org Increasing autonomy of the robot  A special cases for remove unnecessary wiring:  Bipedal robots:  Facilitate the movement and mobility is even greater  The crucial point is the balance of the robot  Misplaced cable or tension, can cause problems in the configuration of the load of the servos. That problems can affect to the instructions of software and eventually cause failure of the mobility tests Flexibility of wireless technologies in learning in robotic laboratories Nao robots pictures from http://www.aldebaran-robotics.com
  19. 19. German Carro Fernandez germancf@ieee.org Increasing autonomy of the robot  A special cases for remove unnecessary wiring:  Interactive robots:  Communication between the robots themselves. Using such tools may be able to get several robots work as a team, improving their productivity by acting collaboratively Flexibility of wireless technologies in learning in robotic laboratories Nao robots pictures from http://www.aldebaran-robotics.com
