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.
Upgrade to ARC Pro
ARC Early Access will give you immediate updates and new features needed to unleash your robot's potential!
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.
