I have couple question about the kit.

If I have servos HS 645 can I use with EZ robot brain.? If I can than how many can I use up to ?


I am really interesting about using lipo battery? However if I use servo HS 645 than do I have to do any adjustment?

Last question, if I purchase I complete kit , which is include heavy duty servos. Are they same size as HS 645 servos?

Thank you.

Most math commands are available in EZ-Script. Having only scanned over the topic very quickly I can't say for sure but can be confident that EZ-Script will be able to manage what you want to do. If the math command isn't there it's usually added by DJ pretty quickly after being requested so just ask if you can't find it, if it exists someone will tell you, if not then it's flagged up for a future update.

Also, I noticed you said you can only read the manual. You can install and use ARC without an EZ-B. You could practice with scripts and use variables, Print or Say to output data while waiting for your kit to arrive etc. I write a lot of scripts without being connected to an EZ-B (in fact I write a lot of scripts without ARC in front of me).

I am so glad to here so. I already install the ARC program , however I prefer to read the manual first. Lol. Nurd!

Let talk about the project! As I skim throught the information about about what ARC can do. I am really interested in the feature "track color or movement." In addition to that, it is kind of inverted kinematic relation control the camera servo. Any opinion for this friends?

I post my YouTube channel please check out some of my project.;) subcribe if you are interested. :):):)

As for those servos - I know the rating is 4-6v, however I have successfully used servos with our 7.4v lipos without issues. Now, as a disclaimer I am not telling you to use them. But, the hassle of wiring regulators for each servo may be more trouble than having 1 servo burn out every year.

If you wish to test, I would recommend connecting one of your servos to the ez-b v4 with a 7.4v lipo battery and have it move back and forth with some weight for an entire evening while you sleep. I suspect it will still be fine in the morning:)

All R/C cars, planes, boats, etc... use 7.4v batteries to power their servos - and none use regulators. FYI:)

Thank you DJ. I plan to use all 18 EZB servo to less hassle. Sorry I will try to be clear next time.

And this is my current project with Botboarduino rover with arm.

@Mr.K... You will be very happy with the ez robot servos... they produce much more torque than the Hitec 645s... I assume we are talking about the Hitec 645s? Anyway, I am going to disagree with DJ somewhat... Probably first time ever...:) But I have had problems running hitec 645s with 7.4v... Granted I have had none burn, but they seem to chatter a lot and seem to have some problems holding position with the higher voltage...
#25  
@Mr.K.... Nice video... Wait until you get your ezb and use the Auto Position control with your arm... It is so much easier to generate complicated movements with servos....

@Richer R

Thank you for the dimension of the EXB servo, I measeure the aluminum chaissis I already had and they are fit. Yeah.

:D:D

Now I just have to save save save money, and read the manual.

Hope you folk don't mind all my questions. *blush* *blush*
#27  
Trust me, I used to ask a lot more than you can ever imagine, and I still ask alot of questions:D
#28  
@Mr.K... We're happy to help.... You know, you can still use those Hitecs with the EZB... Use a 6V battery if you are worried.. Just because I have had some trouble with higher voltages (with hitecs) doesn't mean you will... That way you can grab an ezb now for $99 and buy the servos later....

In the meantime you can play with ARC and see how powerful it is....

I understand that you are going to use 18 servos:) Super cool robot!

I was the one who was not clear... I was asking for you to test with one servo with a 7.4v lipo - test with just one. Run one servo as a test with some weight on it over night. That way you can verify the servos will not be damaged with 7.4v for long operational time.

Just test with one servo to make sure it works - that way you decrease the risk of damaging 18 servos. Instead, at worst you only damage one - if the test is negative.

I have faith that the servo will work fine with 7.4v lipo. This is because not many ppl notice but all R/C are 7.4v with standard servos. This includes all R/C planes, cars, boats, etc...

Quad turning. Just saving for EZ B "brain". ;)

Merry Christmas everyone.

Oh! That's a great robot:) It is going to love the ez-b v4! Hope you are getting the camera as well - the camera really gives your robot life:D
#32  
Lol DJ you read my mind. I really like the camera function and voice recognition functions already there.

I just have to learn more about ARC. Lol I am little lost now, just because I don't have the EZ Bv4 yet.

And DJ how did you make the robot tracking and following object ?

Please point it out if I get it wrong , but basicly the camera send back the coordinate of the object (right ?, this is just my assumption). And how did you convert it back to the individual servo value ( for example the kneck servo or head servo)?

I hope I phrase my question clear enough.

Ah, it's much easier than that... You teach the robot an object, or configure some colors to track. Once you do that, you specify what servos to move, or to move the whole robot, etc..

it'll make sense when you get the robot:)
#34  
Yeah I thougt so too. I am so exciting.
Thank you DJ. :):D

One quick question, if I choose free shipping opinion then how long it will tak to get to Chandler, Arizona ? :D:D
#36  
I think free shipping is based on the amount you buy... I think anything over $200 is free shipping.... As mentioned... Actual shipping time from China is about 3 days or so... However, your order may take a little while to be processed before it ships.... Hard to say how long the processing time of the order will be due to the holidays in all...
#37  
Yeah that is what I was considering about is the holiday. Oh well thank for replying tho.:D
#38  
@Mr.K... even if your order takes a little while to get to you... I promise you, it's worth the wait....:)
#39  
I trusts you. Lol.
Can't wait until the day my robot officially not "blind"
