Ok so I'm thinking of ideas like using servos for drive , mostly because they are easy to replace or upgrade , and I already need to cut out the bottom of Jarvis base to fit the vacuum power head. If I did one servo per wheel that's 480 oz in torque per side. Is this enough to scoot around a 50 pound robot? On carpet? I do have the option to use two servos per wheel which is then 960 oz in torque. The servos would only turn wheels via a gear a axle would still bear the weight so there's no lateral stress on the servos.
The servo I was thinking of was polulu Power HD 240 oz in standard size servo , just 19.99 each.
Accessory axis, perhaps you mean that, at this site there are many accessories for servos, also there axles, wheels and stuff.
This one servo for a similar price but it is not standard size. biggest strength is 33kg (1155 oz)

I think this will do nicely in our bigger bots. Affordable too!
Am I reading this one right? This may be for you Josh

2160 Grades (6 circles) my idea is used in conjunction with a large gear to reduce their 6 laps to turn around (180 degrees) and also multiply their strength by 12.
The other servo 458oz/in. (sorry for the conversion) I have it mounted to move the head of my robot RSP and also I have supporting evidence; of his strength and is impressive and quieter than other servos. greetings.
