WFAR3 Nov. 2012
Competition Robotics
Speed Matters • CIM Motor from Andymark
Free Speed: 5310rpm
• Brushless DC Motors
Very High RPM
WFAR3 Nov. 2012
Competition Robotics
• Light Weight Solutions
WFAR3 Nov. 2012
Problems and Solutions
• Electrical Noise Issues Better wiring, Eliminating the effect of magnetic field
• Communication Noise System gets complex
Multi-controller are used
Communication between controllers
WFAR3 Nov. 2012
Latest Experiments
• Solution to Communication Noise Reduce communication as much as possible: Parallelism
Options:
– Propeller Microcontroller (8-core Microcontroller), it can run 8 threads at a time
– Parallel modules on FPGA
WFAR3 Nov. 2012
Other Problems
• Funds
• Knowledge
WFAR3 Nov. 2012
Funds
• ABU Robocon project funds come from – Center for Advanced Studies in Engineering (CASE)
– Center for Advanced Research in Engineering (CARE)
• Not sufficient for doing good research
• All other student projects are self funded by students
WFAR3 Nov. 2012
Entrepreneurship
• To generate revenue for these projects, we started entrepreneurial activities and consultancy
• We are registered as “RoboTech Engg. (pvt) ltd”
• Products
– DC Motor driver was designed and sold
– Breakout board for dsPIC 33F microcontroller
WFAR3 Nov. 2012
Entrepreneurship
• Consultancy
– IR-SAM prototype was developed, now we get production orders
– Remote surveillance security application
– eSatRol prototype completed, we will also get production orders
WFAR3 Nov. 2012
Knowledge
• We, here in Pakistan, Lacking in technology and latest knowledge
• Solution: Learning and Knowledge sharing
WFAR3 Nov. 2012
Knowledge Sharing
• To learn and share knowledge, we started a new venture last year:
Robosprint: National Education Campaign – National Robotics Competition (rotation based) with three
novel ideas 1. A National Student Coordination Program (NSCP)
2. Special Robotics Seminars
3. National Board as Governing Body: Representatives from all major universities of Pakistan
WFAR3 Nov. 2012
Knowledge Sharing
Rotation of event host:
• Robosprint 2012 was hosted by CASE
• Robosprint 2013 would be hosted by UCP Lahore
WFAR3 Nov. 2012
Collaborations
• We are open for collaborations on
– ABU Robocon
– Robosprint
• National Board
• Seminars
WFAR3 Nov. 2012
Conclusion
• Undergraduate Students: Strength of Pakistan
• Learning/Knowledge sharing
WFAR3 Nov. 2012
Acknowledgments
• All Founding members of CRG
• All undergraduate students of CASE for forming a vibrant robotics group
• Organizers of WFAR3
• Dr. Abubakr: Great teacher and mentor, he is my inspiration.
