Here are photos of the first production version of the Mongoose. **broken link removed**
Front (note the standoffs plus top & forward mounted connectors for your own PCBs or future kits) **broken link removed**
Underside (TTL Serial connector, thermal fuse and a good look at the ball caster) **broken link removed**
Rear (note the ballcaster & 0.1uf caps on the motors if you look carefully you can even see the painted rotation sensor stripes on the blue front gears, it's also starting to rain
Very nice. I was wondering why did you mount the pcb to the the front and not the top? The only reason I ask is that there doesn't seem to be much clearance from the pcb to the ground.
The front mounted PCB is 7.6mm (.3") from the floor. The top was reserved for a breadboard or other user options. There is also a front mounted I/O and mount points for user PCB designs like rangefinders, line followers (where being close to the floor is nessary). It's designed for flat indoor surfaces.**broken link removed**

Which parts/components did you actually make Bill. Are the motors and gears and housing a standard part or did you design and build that/those components?
All the motors, gears and wheels are made by Tamiya. Most hobby stores should be able to get them.
They are very high quality and not terribly expensive. **broken link removed**
Tamiya double gearbox includes motors and gear grease, Mongoose uses the 115:1 ratio setup. Those square holes in the front are ideal for the opto sensor set. (they need only a little enlarging) #70168 **broken link removed**

nice work with the robot - looks like a great platform to experiment with.
regarding the jacks with integerated magnetics, the supplier that comes to mind is Pulse and their MagJack product.
Mouser has the Pulse J0026D21 for $3.49 ... Pulse seems to have a lot of options for the jack with different internal magnetic and wiring configurations, I'm not sure what is normal or what is required by your PHY.
here is the datasheet, I think they've got direct link protection in place, so this link may not work, in that case just visit the website directly and plug the number into the search box.
# With and without LED's
# Various LED color options
# Numerous circuit options for 10/100, Gigabit, and 10/100 POE applications to support all major PHY chip manufacturers
# Fully shielded
That part appears to be a right-angle double row socket. Mike (and I) are wondering where your sourced the SIL (single in line) 18 pin right angle 0.1" socket?
