Well, i know that’s a stupid question, but still - i live in Russia… and i have difficulty finding out what is a thread screwdriver i am to use, while putting the robot together.
Thanks for the answers.
sorry for the mistakes, if any.
I have never heard of a “thread” screw driver. Are you sure you’re not taking the term out of context? All you need to do if find a screw driver that fits the Phillips head exactly. You will never be able to provide enough torque for the screw assembly if the screw driver doesn’t fit the screw head exactly.
strinda, In other words, he means you can damage the screw head by using poor fitting tips. I have found that a No.1 Philips works very well with most of the Lynxmotion Philips screws.
my mistake, thanks for all the trouble - this is “thread screw LOCK” actually - what is that?
screw thread lock is a type of acrylic or varnish that prevents the nuts from being vibrated loose over time. there are different types and some are permanent while others can be removed. the name brand frequently used in the US is Loctite.
thanks, should i still use the nut? or just this screw lock?
mmm? have browsed through the net - there is no such thing in Moscow (Russia), thus i have to find a replacement.
no, no, the thread lock is an adhesive, a glue of sorts, used to hold the nut onto the screw.
I don’t read Russian but this appears to be the Loctite Russia equivalent to the US webpage. henkel.ru/cps/rde/xchg/henkel_rur/hs.xsl/1691_RUR_HTML.htm
Thanks alot… i’ll have a look))
Another question, though from a different area, can i possibly buy a servo controller and a number of servos and build my own robot? I mean, what else do i need? only these two parts?
Because you are posting in the Robonova area I assume you are referring to the Hitec brackets. We sell everything that Hitec has released.
lynxmotion.com/Category.aspx?CategoryID=91
But there is only a limited number of brackets for the 8498 style servo. We have built the Servo Erector Set which is a set of brackets that work with normal standard servos. We have a much better range of brackets than Hitec offers.
It has been along time, since I did anything with a RoboNova, but I remember a lot of people having a hard time with the screws being stripped and there were several suggestions on which #1 screwcriver to use for it. There was discussions about a couple of standards for phillop screwdrivers and you should look for one that is ??? rated. You might try doing a search on these threads or possibly on the ones on the RoboNova site. T
I believe the one I used was from a set I bought at RadioShack, I know that I tried a couple until I found one that did not have any slop.
Good Luck

Robot Dude, actually i don’t really care wether it is going to bу Hitec or your kit…)) I mean - am i correct to think that the only things i need to build a robot from scratch are a servo controller and a number oif servos with brackets?
I believe Jim’s point was to illustrate there are several “standard” servo styles/sizes and so the brackets are specific to the style/size of the servos you choose. There are many, many more bracket options available for the more standard r/c airplane type servos than for the robot type servos used on the robonova, or micro/parkflyer type r/c servos like the HS-55, or quarter-scale r/c type servos such as the HS-805. Which style to choose will impact many design aspects of your robot as well as how much time you spend designing and fabricating custom parts to connect the servos together. 
That’s correct for PC use. If you want to have your bot roam untethered, you will need a microcontroller of some kind (also referred to as an MCU) and a carrier board such as the Mini-ABB. There will also need to be power of some sorts, either by a wall adaptor or a battery. You will need the proper wiring harness to work with the power option you choose. Some sort of sensor(s) is needed for autonomous control as well.
So for PC use you need at least the following:
Brackets
servos
SSC-32
mounting bracket to hold the SSC-32
battery
battery wiring harnes
charger for the battery
Is that what you were asking?
Thanks - that was what i needed)) another question - can i use r\c plane’s servo (they are more available here)? and what is the diference between this servo and a robot’s??
And - why should i need a microcontroller? i mean can’t i store my program on a chip build into a servocontroller (for instance in the robonova there is only one board. Is it already with a microcontroller?)?
Thanks again for the answers))
As for what type of bobby servos will do the job I’m not familiar with the other types aside from hi-tec and Futaba. A true robot servo has a built in controller board (not to confuse you) that allows bi-directional communications. R/C servos are usually weaker and do not have feedback capabilities.
It’s important to note that depending on how heavy your bot is will determine the strength of servos needed. The heavier the bot the stronger the servo has to be to carry the weight.
You do not need a microcontroller to control the bot. You can use your PC via a serial cable or using a wireless Bluetooth device. The SSC-32 does have an on-board memory chip that can store sequence data but there is no logic built in to the controller to make use of the data. A microcontroller or a PC needs to be used to send commands to the ssc-32 to initiate those commands. The SSC-32ng will work more like the Robonova board that you mentioned earlier, where the mcu is integrated with the servo controller on the same board.
I think to gain a better understanding of how this all comes together, your best bet is to start small and work your way up. This field has endless topics with the amount of stuff that can go into any given project. You can go super simple to mind bending complexity. I’m a super simple kind of guy, just ask some of the other guys on this forum. 
Yes standard airplane servos are what the Servo Erector Set uses. Bear in mind Hitec makes servos with the same physical dimensions that they call robot servos such as the HSR-5980 and HSR-5990. They are very expensive but have some cool features. But most people use the HS-475, HS-645 or HS-5645 for robotics.
Yes the Robonova has only one board. It makes the servo pulses and runs the behavior routine at the same time. However we use a more robust distributed computing system. This is where we use a dedicated, but very powerful, servo controller for the pulse generation, and timing of moves, and a separate equally powerful, microcontroller for the behavior.
Why do we do it this way? Because no matter how badly you mess up the behavior program your servo pulses will never become corrupt. Because they are two completely different processors. Also we do it this way because it is much easier to write code for. I think most programmers will agree that safely wrapping servo pulse generation, plus servo move coordination (which is what the SSC-32 does), and a complex behavior routine (Basic Atom Pro) would be difficult to accomplish with $125.00 worth of single chip processing power.
well, finally i face another problem - my pc doesnt want to send signals via com port. It just doesn’t use it, though it is present (and working peacfully) in the “device manager” panel.
Connect the Tx pin to the Rx pin on your serial port. Then using lynxterm, see if if you receive what you send.
could you provide more explanations, please… Rx Tx?
lynxterm?
Tx (pin #3) and Rx (pin #2) below. Lynxterm bottom.
