1HV vs Bioloid vs RN1

[Richo]

I am searching for a robot to use as my main project (im studying mechatronics). To pass we need to build a robot that can make its way through a maze unassisted, so rather than build a boring little car like everyone else i wanted to do something different. After doing a bit of research i came across roboone and then this forum, and i must say i am very impressed with what these robots can do. Anyway after reading through this forum quite a bit as well as other places i have decided to get a KHR-1HV. I had considered the RN1 and Bioloid but keep coming back to the 1HV. I not only want to use this for my project but also want to expand and modify the bot later on.

I am very new to robotics, but i am very mechanically minded and dont feel intimidated by building my own bot, i also have had some experience programming computers. Am i making the right choice? The main thing im looking for in a bot is expandability, something that the RN1 and bioloid seemed to lack compared to the kondo bot.

Ill continue doing my homework but some experienced opinions would be welcome

I don't have any experience, but I do understand the situation and am trying to decide myself.

The bioloid comes with a sensor unit and can be programmed directly in C for at least some brand of AI maybe. However, the manual doesn't even give instructions for building the humanoid they advertise and don't recommend building objects that complex initially...thus, that's out for me. I want a humanoid, not a go-cart with a camera on the front.

The other bots you mention--do they even have sensors? They don't seem to...they seem to be primarily very complex Remote Control toys...very cool, but not things that will go find their way around a course. I do want something highly capable (like those in your list), but I want it to have a sensor add on and some kind of sdk if possible. You have to use a hack to get a sensor in these(like the Robonova I).

I'm not really sure what to do here. This is a hobby. I work as a programmer and am not afraid to dig into some code (although I have never done hardware programming C specifically), but bioloid seems like the only decent bot for AI...
I just don't know.

For me, it seems the older, tried and true Rovonova is the only option because at least there's a hack to put a sensor on the thing.

Decisions decisions...no problem, after all, it's only money.

well from what i read you can add infrared sensors, gyros etc to the 1HV as well as expand the main control board to accept even more sensors. So it can be programmed to be automated.

I decided to get a Bioloid after going to the bioloid forums. That's what I'm looking for at this point, based on what I'd like to do with it, but I think it means I won't be up and walking around for a while after I get it due to the amount of effort I'll need to invest, but who knows.

I'd like to get a robot that's just done and can be programmed to interact with the world using code, but it seems all of the ones above use some kind of gui interface to program moves. No, I need to be able to code too...

I guess I want to be able to do anything...I may get another kind of robot down the road if I have fun w/ this one.

Thanks for the link! I'll check it out.

You can use any bot

Take for instance the Kondo line - use the GUI to pre program the walking and other moves

Then use an add on processor and sensors to detect the environment and choose the desired reaction - and have it trigger the stored move on the bot's factory installed board

Now I can .
I measured the serial port to the RCB3 and found out that
the signal (TTL) is inverted. Inverting (74HCT04D) the signals (White and Red only) and a pull down resistor (1.2K-1.8KOhm) on the input of the TX (white cable) from the RCB3.
If one is interested in a drawing PM me.


Currently I'm trying to get the KHR-1HV (RCB-3HV) to communicate with my controller board (CMUcam3) but I found out the the serial code you sent to the USB-SERIAL (kondo) is not the same as what appears on the 'real' TTL uart output of the USB-SERIAL (kondo).

I didn't came across a posting about this, but I think there are two options:
1- they use RS422 (I have to measure)
2- they remapped the characters in the FTDI chip that is in the USB-SERIAL.
3- Or I'm doing something completly wrong here ,
if that's the case please let me know.

So in my opinion, at this moment, I can't connect the RCB-3HV to a microcontroller board.

Kurt b, I think you got the wrong impression of the Bioloid Comprehensive kit. The Comprehensive kit DOES come with instructions on how to build an 18 DOF humanoid (last project in the quick guide), and their CD and/or program from their website, has a default humanoid motion files and behavior program to get you up and running quick. After I built mine, it was only a matter of software loading to get mine walking and traversing...

The Bioloid Comprehensive is an excellent all-in-one kit to make a humanoid traverse through a maze. The Kondo 1HV and Robonovas are also excellent humanoid platforms. If you go for the Kondo or the Robonova, make sure you pick up an IR sensor or a ultrasonic sensor...

[kurt b]

Yes, it does. I realized this when someone had one for sale here that was built as a humanoid. I found a PDF with the instructions and ensured I was getting the right kit etc (comprehensive), and then I ordered one, which I am building in my spare time. I have the legs and arms done and he ought to be built in a day or two.

I look forward to having some great fun with this guy!

I'll see you guys in the forums no doubt before long.

Hi,

When I first saw this thread I thought all you need to do is program a humanoid to climb over the maze

Any news about your trying to connect the CMUcam3 to the RCB-3 ?

hello Mr.Richo
i don't have any idea about how to make the robot
i only how to use it heeheheheheheh
i deals only in toys
