Using Continuous Servos As Drive Power Polulu Power Hd 240 Oz On Servo


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.


Servos as you know can be extremely powerfull and they are very light and cost effective. I just wish someone would come up with a ready made shaft attachment on them.


That's a very good price for that much torque.


I was thinking, if you disassemble a regular servo, then hook up the motor leads to a single motor Hbridge connected to a stronger motor. Then just fix the servo´s potmeter to the stronger motor´s shaft, you have a very strong servo!


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)


Oooh, Turnigy is a great brand


I saw that servo and my jaw dropped! I thought it was 1155oz/in lol Now THAT would have been a great buy. However its still a great buy but the conversion is 458oz/in.
I think this will do nicely in our bigger bots. Affordable too!


Oh.yea for sure glickclick , that's a reasonable priced alternative, 4wd with all.the wheels having their own servos to drive them , they probably make less noise that a regular DC motor too. For about 100 bucks for 4wd and 50 for 2wd.its really not bad.


Please, Call me Troy. Smile
Am I reading this one right? This may be for you Josh


Thanks Troy I'm on servos but I think I remember something.being different about this kind , but if I could easily modify it for continuous rotaton its probably ideal! Maybe someone could tell us if this kind of servo is ideal
