The Astrobonauts!

Hi!  We are team Astobonauts from the STEM Tech Academy in Melbourne, Florida. Our team meets on Saturdays to work on cool projects like this Energy Transfer Machine, Junior Solar Sprint and LEGO League.

There are 4 students on our team and we are in the Middle School division.

The name of our project is the “ Marywood Energy Trek Energy Transfer Machine”.

The whole team hunkered down in the middle of the “Marywood Energy Trek Energy Transfer Machine”!

Description of the “Marywood Energy Trek!”

There are 16 energy transfers in our machine. Our tremendous machine will unroll the Banner for the STEM Tech Academy. Battery power is used in three steps of our machine:

  1. At the beginning our robot Astrobee will start the machine. He used 6 C-cell batteries.
  2. Later a small crab will be turned on to pull a string. He uses one AA battery.
  3. At the end, our LEGO robot named REDbot will release the banner.  It also uses 6 AA-batteries.

  • That was amazing! Really enjoyed seeing the different steps in the project and so great that the end released the balloons and showed the STEM Tech banner! Lots of pride showing there. Great work, congratulations.

  • Amazing! I love how you used robots in your project! Lots of creativity inside of the it too

  • It looks like you had a lot of fun with the large space you had…..the elements of your machine are large, showy and varied. I love the rocket, the large bell, the marbles rolling down the metal tube (I love the sounds made from these machines), the large turn-table and the balloons being released at the end. So fun!

  • This project is very well done. I appreciated the number of steps you had and the degree of difficulty. As a viewer, I also liked the large scale so it was easy to follow and see exactly what was happening. Nice work!

  • Very creative and well done! I really liked the large scale and variety of steps you included.
