Audition Tape for #badass Women Makers and Engineers Contest

vidyamohanan

Hi Everyone,

 

I am Vidya Mohanan. I hail from the Indian state of Kerala. I am a Computer Science Engineer and currently work in an IT company.

I always loved to tinker with electronics as part of my projects which I used to work during my college days. The Element 14 Women makers and engineers contest seems like a good opportunity for me to get back into my hobby.

 

Please find my audition video here:

 

This video is unavailable.

 

Regarding my previous project, I have worked on a gesture-controlled robot using basic robotics parts and Inertial measurement units. As you can see in the video, the hand gestures are captured using an MPU-6050MPU-6050 IMU pair and processed in an Arduino Nano to determine the motion of the robot and the servo system mounted on it. It has a lot of applications in industrial as well as military sectors. Some include control of manipulators or targeting systems according to the gestures captured from the operator.  I do not have the hardware with me right now as it was submitted to college years back. However, I am attaching a video that we recorded while testing the project back when we worked on the same. For this contest, I am planning on developing and upgraded version of this, with more cool features and precision.

I hope this contest is a great motivation for all the women hobbyists out there. Thanks to element14 for hosting such an event and I look forward to taking part in this contest in all the three phases.

 

PS: I apologize if the video clarity is not the best as I lack a professional arrangement to record the same.

  • Nice one, what I figured out from the video is,

    raw A&G values are used to control the servos, similar to wired IMU controller projects. Have you tried to use the DMP feature of MPU unit. You can also try to control the bot through IMU compensated Vision Intelligence, and use a wireless link like WiFi instead of wired connection.

     

    Best of luck for your upcoming projects on E14.

    thanks. This project was done during 2013-14. So for us the MPU 6050 and even the Arduino was quite new at that time. We had used the DMP on both the IMU's, but the yaw rate was still bit of an issue. To be frank, we tried to make it wireless using RF approach, but due to time constraints and repeated failures, we had to leave it. Now, if I redo the same project, I would definitely go for wireless as more feature-rich and affordable modules like ESP32 are easily available.
