Project Update 02-25-04

I got this little guy in the mail this week. It was only $33 bucks after a carton of 2000 BB's and shipping. The gun itself was only $12 or so. I picked it up from http://www.airsoftatlanta.com/electric.htm.
I was going to rig it up to my servo playground but ummm it shoots really hard and fast and I'm afraid someone will shoot my eye out and make a mess of my office. We shall see though.









I got these this weekend off of an old go cart that my dad had gotten for me and my friends and his grandkids a long time ago.
They are 14-15 inch or so, a little bigger than what I was originally looking for but they will do fine for my robot. I was really pleased when I saw them because I was afraid that the tires would be two sizes, smaller in the front and larger in the back. All together these things will probably save me about $120 in new tires and rims etc. I may have to replace some of the tubes though and they are rusted up pretty bad. Also, the hubs are not made for a live axle as my current design will use. So I'll have to replace them or modify them. I may just make my own.
The go-cart was driven by a single chain and the tire that it was attached to was pretty bald compared to the others, I may replace it later but its not so bad that it wont work at all.





Here are some sprockets I picked up as well to fit on my motors.
I showed my brother, Lee, my two current ideas for the chassis etc. He suggested I go with the version with the motors in the center of the two side wheels instead of directly connected to one of the wheels. This would allow us to gear up/down the system. I decided on #35 chain and got some advice on how to mount the axles etc.
Armed with this new info I made a few new designs and modified my old ones etc.
I'll get into that with the next update as well as some modifications I made to the little BB gun.
