Thanks everyone for the comments.
First off as Henry stated, we the transmissions in our high school shop. Most everyone on the build team was involved with making the transmissions mentors and students alike.
I had the fun job of making most of the 1'' shifting shafts.
Also as Henry stated we got the idea of ball bearing shifting from a Hodaka motorcycle transmission that was produced back in the 70's.
We took that concept from the Hodaka transmission, which was a 5 speed, used our creativity and then figured out how to make it work on a robot.
We did have several ideas for shifting them, from Globe motors to servos, but we ended up using Pneumatics for reliablity/simplicity.
Several teams this year that used this shifting method include 1143, 571, 469, and there are more that I can't remember at the moment, please let me know if I missed you!
If any of you have questions about the transmissions just feel free to email me
rigdonbrad@gmail.com or AIM bsrtunkpa.
233 did have a really cool arm design, I got my first chance to see their 2005 robot in action at IRI.
I have been thinking about make a new white paper on the 2005 transmissions and making other white papers such as how 222 builds simple aluminum robot frames that with stand constant abuse.
