Challenges of Engineering Project

Even with all of the resources I have for planning projects, sometimes the best ones come from just being in the right place at the right time. A couple of months ago, I took some students to the first National Science Fair in Washington DC and we had a great time seeing all of the universities and organizations who had shown up to renew the country's commitment to STEM.

One of my favorite exhibitions was with Disney/Imagineering and the National Institutes of Health. They were partnered to demonstrate innovation in one of the critical Challenges of Engineering that were produced by the National Academies of Engineering. Some examples are cyber security, solar energy, personalized learning, and 11 more.

When I came home, my humanities teaching partner mentioned to me that she would like to work on the technical writing skills of our students. An idea for a project was born and after some collaborating, we had decided that we would have the students create research paper/posters based upon the Challenges of Engineering.

This was a valuable project for many reasons:

  • It did help the students learn about these important topics that threaten the survival of our society as we know it. Students began with almost no knowledge of these topics and yet at the exhibition were able to impress community members we had invited with the depth and breadth of their knowledge.
  • Students worked diligently to research these topics using college level resources and understand it in a way that they could explain it to others.
  • This provided them an opportunity to create beautiful work through feedback and refinement.
  • We set a high standard of excellence, our model and criteria were based upon the same used for Graduate School work, but the students rose to meet our expectations.

Science, Technology, Engineering, and Mathematics at the National Mall in Washington D.C.

What an exciting event. America is renewing it's support and interest in STEM (Science, Technology, Engineering, and Mathematics) with the first annual USA Science and Engineering Festival. It was exciting to bring our virtual bike to the fair, but there were many other exciting booths and events.

It was uplifting to see hundreds if not thousands of people come to ours and the other booths. Organizations, Corporations, and Schools of all types came out to get citizens of all ages excited about science and engineering. So often we forget that it is possible to have fun while learning but events like this are just what is needed to remind us. I also appreciated the chance to meet and talk with educators and business people from all over the country and hear their passion and interest in getting interest reignited about science, technology, engineering, and mathematics.



Everyone did an amazing job and brought some wonderful exhibits. Here are a few highlights:




There are so many potential discoveries and opportunities in biology and genetics so it was great to see so many exhibits teaching about DNA. Students of all ages learned trascription/translation, how to extract genetic material from fruit, mutations, and much more.






Robotics was a big player in this festival. Almost every type of robotics team was represented at the fair. VEX Robots were playing soccer, BotBall bots were following obstacle courses, but FRC stole the show with its high powered catapults and launchers. Who wouldn't want a robot that could shoot a soccer ball 20 feet into the air?



The National Academies of Engineering and Disney's Tron had a line out the door with their exhibit on Virtual Reality (you can imagine why we took an interest). Partnered together because of the NAE Grand Challenges. It was mindblowing to see the virtual technology being used to improve neurosurgeon's precision. As they practice, they are able to see if their stress levels are high, as well as practice on a realistic simulation. Apparently one cannot learn everything by practicing on a cadaver. It will be amazing if the top surgeons of the future can trace back their skills to practicing on video games like this.



Thanks to all who made this event possible. My students and I would definitely come back to exhibit another ground breaking innovation by the Chaos Vortex Robotics Team from Chula Vista, CA.

Virtual Bike at the National Mall in Washington DC

After almost a year of preparation 4 of my students are bringing our virtual bike tour of the Otay Valley Regional Park to the first ever USA Science and Engineering Festival in Washington DC. How did this happen? Let me back up and tell you the story.

The incredible Lisa Davis approached me about participating in the HP Grant our school was receiving to encourage the implementation of technology in the classroom. Through this grant we received laptops and scientific sensors.

One of the organizations we were were connected to work with was Wildcoast and the Otay Valley Regional Park. Through our discussions, we learned that the largest obstacle the park was dealing with was obscurity. There are miles of beautiful trails and natural resources that much of the San Diego community is not aware of. So we decided our project would be to help make the community more aware of this park while encouraging the use of technology.

After some brainstorming and prototyping, the students developed a basic 15 second movie of what was possible. The video was created using Blender a free and open source 3D Rendering Software. I have embedded below the prototype video (which the students despise because they have learned and improved their skills so much since then). 



Wildcoast and HP were extremely happy with our idea and so we received the green light and funding to move forward. After months of work and learning along the way, the students refined their work significantly. The user sees the virtual park through Virtual Reality Googles we received through a sponsorship with Vuzix. With the built in accelerometer, it is possible to look around 360 degrees within the virtual park.

The bike was donated by REI, and while were unable to bring it with us for logistical reasons, it is quite an exciting experience to ride. Using force sensors from Sparkfun Electronics and the Arduino Microprocessor, the game is able to detect when the rider pushes on the pedals and moves them forward in around the park.

The final video file is huge and I am unable to show you a video inside the final version of the park, but here are screenshots, pictures of the students working, and pictures of people enjoying it at the USA Science and Engineering Festival.


I hope you will be able to stop by and say hi, this is a result of a lot of student (and teacher) effort and we are honored to be a part of such an exciting event. We will be located in National Mall 3 on 4th Street. Next week I will post pictures and a report about the other events and exhibits at the festival.

Impact a Student's Life by Starting a Robotics Team

I have spoke in the past about the importance of After School Programs. My after school program is a robotics and engineering program. I love robotics because it teaches all of the major aspects of engineering (mechanical, electrical, programming, pneumatics, etc). It is wonderful to see something that you built come to life (very Dr. Frankenstein).

The students love it for this reason, and that every year the organizations frame the challenge in the form of a competitive game. Through teamwork, and ingenuity, students learn engineering and life skills.

At every competition I see educators in the audience get hooked by the excitement and motivation of the students. They want that for their students and the question is, "Which robotics competition is right for me and how do I get started?" Here is an overview of each of the main organizations and some tips on how to get started:

FIRST - FIRST is For Inspiration and Recognition of Science and Technology. It was started by Dean Kamen who invented the Segway but also the Insulin Pump, and a Water Purification machine. His philosophy is summed up in the following quote, "In a free culture, we get what we celebrate." Seeing sports and celebrities being idolized by students but not engineers and scientists motivated him to start FIRST.

FIRST has been around for over 25 years and is a huge and diverse organization. The original competition FRC (First Robotics Competition) involves students building a large 120lb robot from scratch. Students have 6 weeks from the Kickoff event in early January to design, build, refine,  and test a robot. The students compete in regional competitions and the winners move onto the World Championship. The events are truly exciting and newcomers will be hooked immediately as they are just as exciting, if not more, than any sporting event.

Tips for FIRST:

  • FRC has a significant cost, teams spend $6500 to register and pay for their first regional, and up to $3500 for the actual building of their Robot. However, there are many companies willing to help out. FIRST has been around long enough that companies and colleges are well aware of it.
  • Creating a robot from scratch can be a daunting task, but while this is a competition, FIRST seeks to usher in a world of Gracious Professionalism. This means that teams are willing to share and help out one another for the true goal of learning and enjoying STEM (science, technology, engineering, and mathematics). If you are interested in starting a team, the FIRST robotics website will help you find workshops and other teams in your area who will gladly help out.
  • Do not be discouraged if you are not yourself an engineer. Companies will gladly donate mentors to your team to help you out in all aspects of the program. This is another component of FIRST, getting students integrated into the community of professionals. Additionally, my previous Robotics Team MorTorq won the 2010 Chairman's award, the highest award one can receive in FIRST. This was done through the incredible leadership of Eileen Kahn who herself is a businesswoman. Through their partnerships though, the students were never at a loss for expertise. 

VEX Robotics: VEX was originally a part of FIRST but became so popular that it became its own organization and competition. These robots are much smaller (18"x18"x18") but the excitement and learning is as significant as with FRC. 
  • The cost is far lower than with FRC. Teams can build a great competition robot for well under $500. Many teams will use VEX to start their robotics team and then a couple of years later add on FRC.
  • VEX is great for prototyping, or testing ideas and designs. It takes less than a week to build a VEX robot and the parts are analogous to larger parts (e.g. gear ratios, torque).
  • These robots can be built by elementary/middle schoolers with support and the programming software Easy C teaches programming concepts while keeping the difficulty to a minimum.

Botball - Similar in size and cost to VEX, Botball has a much more significant reliance on programming and sensors as their robots are completely autonomous. This means that there is no human controlling the robot duing the competiton. Additionally, the parts are Lego Technic pieces. So while they might not be as robust, the time to build a robot is much faster. This makes it very useful in a classroom for exploring programming and robotics.

BEST - The BEST robotics program was inspired by Woodie Flowers of MIT (and later FIRST) with the hopes of bringing engineering and robotics to High Schoolers. The robots are larger than VEX or Botball but tend to be smaller than FRC robots. The parts are hardware like PVC and Wood, in addition to standard motors and electrical components. BEST is significantly different from other competitions in how heavily they rely upon other aspects of a team besides the robot. To go see a competition you will see beautiful and elaborate booths filled with detailed engineering notebooks, research, and financial documentation.


If you wish to sign up for any of the above Robotics teams, there is still plenty of time. Go to Robotevents.com and sign up your team and register for competitions. Opportunities for funding can come from the numerous grants available for STEM, private corporations, community businesses, organizations, fundraising, and many more. People are going to come out of the woodwork to donate to your noble cause if you keep your ears open and mention it to everyone you meet.

Let me know if you have any questions about starting, funding, maintaining a robotics team. Trust me, once you start, you and your students will work hard but love every minute of it.
