This project has evolved some , the basic rundown is I'm modding two Omnibots , one a regular the other a larger 2000 model. I will have two ezb kits , rad base idea was thrown out because of so much noise but could go back on the table if the omnibot drivetrain is too weak to pull it.

HI Robotmaker
Is that about 100 pounds of torque.
Gees he will be a right little ARNIE . A proper bender unit.
Steve_C.
yes its near that,right now working on the riser and aluminium frame i may not need a 100 lb or more,but if use less then a lot less current is used tracks i have can handle 140 lbs using VEX robotic tracks and high torque motors 4 at 35 lb each

Iv been catching up on your thread ( takes a lot of reading dude )
you can use a data selector ic to use all your sensors. Use 1 output to switch between 2 banks of sensors.
then have 2 (or more) modes in your software .
EG
mode 1 navigation . all sonar and ir distance sensors.
mode 2 intruder detection . all your pir and mics + gas sensors.
you can switch off the unused sensors to help save power , and all for a couple of bucks.

thats kinda like my design on 8 or 16 more analog inputs using a data selector i gave that ideaa few pages ba ck about making a board and selling them or if others cant solder,i can do it for free
@robotmaker
It is a very old design . I used it to control my train set with a old commador 64 , A long time ago .
8 bit output port controling 16 points + signals + lights.
Very easy to do and really cheap too.

@STEVE_C the analog chip is CD4051,i know its a old design,that chip is used in test equipment and in house testers i design,you need one analog port and 3 digital ports to control is to get 8 extra analog ports in total of 15 ,CD4053 0R CD4052 ARE 2 4 ANALOG PORTS IN OR 3 ANALOG PORTS IN AND YES CHEAP $.50 very low rds on and very low current since it a cmos chip pdf file on it cd4051 multiplexer
Just read your post , no mention of a data switch there robotmaker. I was just clarifying the idea so josh can keep all his great sensors if he wants them.
The old TI chip i used in the 80's was pre cmos and needed i well regulated 5v . As you say the newer chips are alot better , faster and cheaper . ITS ALL GOOD.
Steve_C
my design is a data switch,i guess you meen the old 7400 series chips i almost know every chip made and used most of them,even design a very ultra high pure sine wave source with precision feedback,getting a pantent for it for the test equipment company i work for will buy the design ,they gave me 2 months to decide on the amount
if you need my help on any design i can do it free.only not good at programming yet
