Please can I use arduino uno to program this motor and also it need driver or not?

You do not need a driver, all you need to do is provide 12-24 VDC. I have corresponded with the manufacturer and they recommend 18 VDC. I plan to use this at about 21.5 VDC (what a typical 24 VDC power supply can be turned down to), in which the manufacturer approved as an upper limit. To control the servo, you need to provide a PWM signal, which I think is available from an arduino. The PWM needs to be at 50-400 hz and have a pulse width from 500 usec to 2500 usec. Sorry for the remedial math here, but .5 to 2.5 milliseconds would be the correct pulse width to make this go from 0 to 360 degrees of rotation. I have tested this with inexpensive RC servo test devices and it definitely works. There is 5 VDC available for the signal input, so you could use an open collector output. If the arduino has a lower voltage, such as 3.33 VDC, I'm not sure if that would work, but the sales data on Amazon supports this. This servo is accurate and has a great deal of torque. With 21.5 VDC power applied I was able to get about 67 rpm out of it. I hope this helps!

How many amps does the servo pull at full power and 18V?

no load is 0.34A/18v, max load is more then 20A/18v, very powerful

Are servo arms available for this product?

No but there are some cool examples on how to use this for a quadrupole robot

Can this motor be used to steer wheel to specific angel? In continues servo mode?

Yes. The servo has two modes: servo position and motor drive, which is selected by a DIP switch. In servo mode the shaft rotation can move 0-360 degrees for 0.5 to 2.5 uSec pulse width. There are gain and offset potentiometers to calibrate the motion over any standard servo range. There is also a reversing DIP switch to change the sense of the rotation.

Exceptional Power, Easy to use.

The DOCYKE High Torque RC Servo (550kg) delivers truly exceptional power that is perfect for demanding projects. While I unfortunately managed to strip the gears due to a personal build error, my experience with the company's customer support completely turned things around. They were incredibly responsive, helpful, and efficient in getting me back on track by allowing me to purchase the necessary replacement parts immediately. I am thoroughly impressed by their commitment to their customers and deeply appreciate their prompt assistance in resolving my issue.

Very strong at this price

The difference between the s350 and s550 is the planetary gear ratio. I use both of these. The S550 is slower but has 57% higher torque. The mounting holes are the same. Electrically they are similar. The power connector on the s550 is capable of higher current and is an improvement over the 2.54 mm spaced pins on the s350. My application needs two of the higher torque units, but the final drive gears failed on one (per mfg specs, the motor torque limit should have prevented this). Amazon immediately replaced the bad unit.

Beefy

Slings a ten pound weight around like nothing. One of the beefiest hobby servos I've used and will be getting more. Just wish I could get individual parts from kits on here

Excellent servo for robotics

I am building a large (5 foot tall) robot for Halloween and needed a way to rotate the head (a 16" plywood cube). This easily handles the job and is far more powerful than the strongest 1/5 hobby RC servo that I could find at double the price. It also has a D-profile 8mm output shaft which is much better for high torque applications than a 25T RC servo output. I really like the manual potentiometers for precision adjustments of center point and range. Mounting this is easy as well. Lots of holes with pre-molded nut retention, etc. The plastic housing I believe is glass reinforced nylon so is very strong.

Fix it

There are a few holes for fixing the body to a surface. These holes do not have standard industrial screw sizes. There is no documentation about the size selection or the appropriate screws for them.
