I was so interested in robotics when I was in my Bachelors. Created a team with 3 friends. “Carriers” we were called. We participated in so many competitions , unfortunately I have lost most of the photos and videos.
Recently while talking to a colleague who is a mechatronics engineer I remembered one day I wanted to me him. So, I did a bit of time travel into the past , thought about the old websites I used 10 years back, and Voila!! found Dropbox to my rescue!
Here is the trial round video of a robotics competition that we finally won. I know it’s hard to believe considering how inaccurate this Robot is right? Surprisingly we managed to make it super accurate as we progressed through the rounds.
All using frugal Indian innovation. We used plastic bottles, thrown away packagings, used switches etc. The whole cost would have been just a few euro cents.
Oh, I didn’t even talk about our special mechanism. How do you make a robot pick up balls and throw? How can you build a hand? No, you can’t use 3D printer etc.
- Cut a plastic ball into two halves, attach a motor to use as hand?
- Attach two spoons at the end of a scissor mechanism and use a linear motion?
All these hand mechanisms look cool but they are limited to mechanical design and precision. We just used a water bottle and cut it’s base. Then we attached an elastic band to the open mouth like a cross.
If you press against a ball with this, the ball will enter, by expanding the band but cannot leave as it’s weight is not enough to expand the band.
