Hi. Can i use micro servo at robotic arms? How much waight they can lift?
micro servo
- Thread starter shah_siddiquee
- Start date
A typical stall torque for a micro servo is 1.6kg/cm, so with a 1cm arm, the servo will stall!!! But, that does not mean it can lift 1.6Kg.
Typical arms are a little longer than that at 1.5cm so reducing the stall torque to ~1Kg, the problem is no-one ever specifies lifting capability as there are too many variables to give an accurate figure.
My estimate is a bout 200-300grams, but not much more.

They can lift themselves, see the video at

I reach across 30cm or so from where I am sitting, and grab a servo in its original box.
1.1kg/cm it says, is that a 'micro' servo ?

@Shah,
you must learn to provide sufficient information for folks here to make informed decisions and help you.
That way you will receive a response closely matching you requirements qquickly.
In the current case, we need the make and model and preferably the link to the website and/or datasheet for the item in question (the servo) so we can see the Nm rating.
In simple terms, Nm is how much force (newtons = N) can be exerted at a distance (in meters = m)
Then Newtons is in effect kg * force of gravity.
So take the Nm value, divide by the distance from the shaft to the weight in metres (1 m = 1000 mm)
Then divide the N by 9.81 and you get kilogrammes (kg)
