Some Early Attempts
I went through a lot of chassis designs until I finalized on the one you see pictured above. Here are some attempts and what I liked and did not like about them.
|Here is the first base design. It was very sturdy but the middle plate kept getting in my way.|
|Here is the bottom of the first base design. It shows the two motors, two casters for a Diamond wheel base (which wobbles by the way) and the encoder wheel.|
|Here is the top of the first base design with speed controllers attached.|
|Here is the bottom of the first base design. It shows the a single battery where I housed the microcontroller and power distribution.|
|Here is a picture of Feynman 3 with a laptop attached. Although it worked well I found the VIA single board PC for $100 from an article at robots.net and it just lasted a week-end.|
