Hi Everyone!

I just discovered this great place a few weeks ago - Been lurking and now I have a few questions…

I have 2 boys (6 and 4) and we have the original LEGO robotics set and the newer NXT set. We’ve built Wheeled, Tracked, and BiPeds, and now are looking to go to the next level.

I am thinking of going with a Hexapod like the Phoenix or the CH3-R.

I was wondering what everyone thought about the 2?

Pros / Cons - Whatever you can tell me :slight_smile:

I think the phoenix is pretty advanced building due to how tight it is and a lot of the code development is not so canned and proven.
The CH3-R is much more comfortable size wise and has been around long enough that there is a wealth of sample code and proven modules established. For younger kids I think you’ll get just as much interest and appreciation with less close in + figure it out work with the ch3r than the phoenix.

Hi,

Welcome to this forum!

Just a little question first. Are you going to let your children play with the robots too? I have to warn you about the danger about that, since the servos are pretty powerful, they can give you a VERY hard pinch. Keep fingers away when the robots are powered.

Anyway, this question has popped this forum some times now and I would recommend doing some searches.

Main difference is the body size and leg design. CH3-R can carry more good stuff, but Phoenix has a smaller more flexible body.

Thanks Guys!
I will be letting the kids help build it and use it, so I’ll be VERY careful with the servos! They won’t be using it EVER without me :slight_smile:

I will search for a previous thread on this too - Thanks guys!

OK - I did it!
I ordered a CH3-R last night!!! We’re VERY excited!

I’ve downloaded all the instructions / manuals / etc… that I can find and have questions about servo calibration.

I purchased 3 of the HS-645 “6 Packs” with the metal servo horns.

Will I have to calibrate the servos for this bot?

If so, will I have to it PRIOR to assembly, or is it done post assembly?

I spent so much cash on it last night, I didn’t want to spend any money on the servo programmer / calibration stuff if I don’t need it.

The HMI programmer is out of stock and doesn’t list my servo in the description anyway, and the HFP is sooo much more expensive!

Thanks in advance for any info on this!

HS-645 servos are analog so you don’t have to worry about programming them. :wink:

usually there is an alignment procedure in the tutorials where after assembling much of the brackets you then power the servos up, send them to “1500” with lynxterm or another of the applications, and then the tutorial will tell you how to set the servo horn onto the spline (presumably with the bracket attached to the servo horn) so that the canned programs will work properly.

We appreciate the support, you will not be disappointed. :smiley:

The servo calibration is done after the robot is assembled. No additional equipment is required. The assembly guides are pretty straight forward, but if you have questions we are here to help. Thanks!

Hi kmc123,

You’ve bought yourself a great robot platform! I’m sure you will enjoy it. How are you planning to control it? With a pc or with a ATOM?

Let us know if you’ve got any questions.

I got the ATOM - I’d like to move to the ATOM PRO after I get it all working - Anyone else using the ATOM PRO on this bot???

I’d also like to try out the Microsoft Robotics Studio as well…
LOTS of choices and ideas :slight_smile:

The UPS site says it will be here next Tuesday and I’ll be out of town :frowning:

I knew I should have paid for 2 day delivery!!!

Yes, I use the Atom Pro. I did an earlier conversion of the code that Powerpod generatest to convert it to run on the Atom Pro. Also Have had Xan’s code (phoenix) running on it as well.

Welcome to group.
