Junior BotBall Challenge Grant



Last Friday I received the official notice that I have been awarded the Junior BotBall Challenge Grant from the Oklahoma State Education Department. I already had my robot kit from a workshop I attended earlier in the school year, but it is nice to have the grant finally cleared. The email was perfectly timed since the BotBall team attended our first Regional Event last Thursday.

What makes Junior BotBall different from other robot building competitions is the students are competing only against themselves. There were about 18 challenges at the event, and each team tries to complete as many of them as they can in one day. The basic challenges are the same from one event to another, so as I team finishes one, they do not have to repeat at the next event.




Unlike the ArtBots that you can find on my blog, these robots are more sophisticated, and much more complicated to use. The black box is actually a small computer, that we save our programs to, and that runs the robot. Junior BotBall uses C program language to write the code that controls the bot. 

Which means, we first had to teach basic coding skills, and how to understand the syntax for the C language. Once students had an understanding, they were able to start writing code,and completing challenges.  



Here is an example of a challenge. 



Each blue section was a different challenge to complete. This was taken at the end of the day. The table area across is called Pit Row, and each team acts as a Pit Crew for their bot.

Here is a sample of the code that controls the robot.
The program is written in C Language.

ArtBots


ArtBots are an easy introduction to STEAM. They are very simple to make, and touch on Science: Circuits, Movement, Balance; Engineering: Designing and building the robot; Technology, and Art. ArtBots can be used incorporation with Project-Based Learning.   





Like many art teachers I try to make some time to look for new ideas for my art program. There are several blogs that I often look at, many which are listed on the left side of my site. I also search the massive collective that Pinterest has to offer. I like to vary what I am looking for from different mediums, cross-curriculum projects, and technology. 

At some point during the past year I stumbled upon ArtBots and BristleBots (that is another post). I don't remember the first time I saw one, but I do remember wanting to try it out. They are a perfect blend of Science, Technology, and Art. And come on we are talking about robots!

ArtBots Supply List


ArtBots are not completely free, but you can make them with little cost. Best of all you can use them again and again.


  • Most materials are easy to collect.
  • Reuse containers to save on cost.
  • Get creative with electronics.

Electronics

  • Old motors
  • Electric Toothbrush (Dollar Store)
  • Personal Fan (Dollar Store)
  • Video Game Controls
  • Pagers
  • Radioshack (Can get pricey)
  • Anything that spins or shakes.

Construction
  • Batteries
  • Tape
    • Masking
    • Duct
  • Pool Noodle or container
  • Markers
  • Rubber Bands
  • Wire
  • Aluminum Foil


Decorating

  • Pipe Cleaners
  • Wiggly Eyes
  • Buttons, etc.
  • Scrap Paper




VERY IMPORTANT!!

By adding an eccentric or off center weight to the motor you make it shake. That rocking motion allows our bots to draw. 

If you weight is to small, your bot will not dance, if it is to heavy, your motor will not spin.



Here are some images from my latest builds, and from the last workshop I taught.





In this video I am explaining one of my ArtBot creations.
