Arduino Robot Challenge: How inexpensively can you create a robot using an Arduino for 5th Graders? Answered
PLEASE VOTE FOR MY PROJECT!
So here is the challenge: For the lowest amount of $ and ease of part availability create a robot that can be used to teach 5th graders via "physical computing".
I have been on a 4 month journey of learning...lessons learned so far are heavily influenced by: SERB AND Mothbot ...Instructables smart ads on the sidebar just led me to this exciting solution: Babuino!
Some of my thoughts/guidelines/rules/challenges:
- Use K'nex. Cheap, available, and familiar to the kids.
- No tools required!
- Use Arduino. Assume $30 cost. I know many other options exist to reduce this cost...but for now keep it simple!
- Use Scratch for Arduino. I have donated PC's from my employer and plan on loading Ubuntu...another zero cost aspect!
- Start in "tethered mode", later on go to Xbee link to PC...or hope that S4A gets the unlinked mode working soon.
- servo's seem the best approach to drive without extra requirements....GWS S35 STD Continuous Rotation Servo Motor is the one I have from Mothbot.
- However, I would like to use the motor that comes in the Robo Battlers K'nex kits....
- So I am thinking of a robot base consisting of a DC motor rear 2 wheel axle...still trying to figure out the best circuit to allow forward/reverse...not too worried at this point about speed control...maybe later?
- Steering could be via a front axle controlled by the GWS servo...I think? However, it appears that steering can be difficult via K'nex.
Me, my teacher partner, and 21 5th graders thank you for helping meet this challenge!
