Another demo features the infamous rabbit hop that was a key judging criteria for the recent ROBO-ONE 10 competition last month. JR even went to the trouble to add some neat sound effects emphasizing each hop. It's a great demo to impress other builders, and does show off the robot's leg strength and balance. But it's not something you want to encourage customers to do with the robot regularly since it can result in some pretty severe gear and servo damage.

We should make it clear that there are several different RB-2000 series configurations shown during the demos, and some of the functionality is 'optional'. As you might expect, the higher the model number, the more degrees of freedom (DOF), and the higher the price.

Their original humanoid robot (Fri Mar 12, 2010 4:05 am)

Fri Mar 12, 2010 4:05 am (GMT 0)

Their original humanoid robot offering, named the RB-1000, offered good performance at a reasonable price, but for some reason didn't attract a lot of attention both here in Japan and overseas. With the new RB-2000 series, JR has put a lot of time and effort into creating several "WOW" demonstrations that they hope will create a strong impression in the mind of the buying public. We caught up with them at the show on Thursday, and managed to capture some of their demos in the video clip below.

RE: I want to walk, and keep walking. (No pause) (Fri Mar 12, 2010 2:14 am)

Fri Mar 12, 2010 2:14 am (GMT 0)

basically, firmware motion should be changed,

I haven't tried yet. So I am not sure.
but my idea is
1) Download the "super speed walking" from RB website.
2) Control RB by bluetooth controller, NOT by IR remote.

I will also think it over this issue~ and will let you know the solution

RoboBuilder by MSRDS Serial Port (Fri Mar 12, 2010 2:05 am)

Fri Mar 12, 2010 2:05 am (GMT 0)

Hi,

I'm keep studying MSRDS thesedays with RoboBuilder,

and just found that the MSRDS Serial Port Service article in the below
http://msdn.microsoft.com/en-us/magazine/ee309885.aspx

This would be useful for someone who programs in C#
Because C# is totally compatible with MSRDS.
Since RoboBuilder published all RBC protocols (PC Control Mode, Run Motions, Sound.....etc..), now we can control all the RoboBuilder resources in MSRDS environment~

Yes - with C# its very easy to do what you need. The code looks something like this (call with pn would be set to name of COM port):

Code:

using System;
using System.IO;
using System.IO.Ports;
using RobobuilderLib;

public int connect(string pn)
{
string serialNumber = "";

try
{
SerialPort p = new SerialPort(pn, 115200, Parity.None, 8, StopBits.One);

p.ReadTimeout = 1000;
p.WriteTimeout = 1000;

PCremote pcr = new PCremote(p);

p.Open();

serialNumber = pcr.readSN();

p.Close();

return 1;
}
catch (Exception e1)
{
return 0;
}
}

See top of thread for more info on the class.

But for example to read the PSD should be:

string res = pcr.readDistance();

or read accelerometer:

int[] result = pcr.readXYZ();

Or to run a motion (in this case basic pose) put:

pcr.runMotion(7);

If you come across problems please let me know and I shall try and fix

regards

Wow! I had completely missed this incredibly useful thread about C# Coding!

I haven't had much time lately to code, and I've been mainly researching about how to transmit through a Com port, open/close Coms, detect Robobuilder, etc. using C#.

Will this code/library allow me to communicate with the Robobuilder through the COM port, and make it easy for me to send commands and queries using the RBC protocol?

I have decided to retain the original firmware of the Robobuilder, as this will simplify things for me now. The only things I want to achieve for now is to send some commands to the robobuilder, and receive some data, like PSD values.

Keep up the good work,

Alex

When I did this step on the roboard software training:

Copy all files in Roboard\Winioto your application directory or Window�s System32 directory

I put the winio directory intothe system32.

Doesn't work.

When I copy the winio files into my application directory it works.

So I answered my own question. Thanks self

Getting everything together for the weekend, been working out a bit of a show between the rover and the Manoi. Should be quite entertaining.

We will be in the main Centre for life, not sure of the exact location until registration on the day.

After looking at the example I modified the else statement to try to get the the error message

Code:

else{
cout << "ERROR: RCSERVO lib fails to initialize \n";
cout << roboio_GetErrMsg();
}

That yeilds:

ERROR: RCSERVO lib fails to initialize
I/O library fails to initialize

Microsoft Robotics Developer Studio 2008 (Thu Mar 11, 2010 6:20 pm)

Thu Mar 11, 2010 6:20 pm (GMT 0)

Has anyone seen anyting specificly services for the Microsoft Robotics Developer Studio 2008 design to interface with the RB-100?

I am currently in the process of embedding the Roboard into:

http://www.facebook.com/l.php?u=http%3A%2F%2Fwww.facebook.com%2Fv%2F335244683607&h=3f912f0ec15c10b274855220f9afbf2b

Sorry not a walking robot yet. Just a wooden tank.

I will be adding a layer or processes to control motors, sensors, GPS, Compass, tilt, and other hardware level devices. These processes will talk to an Local SQL database on the roboard.

From the SQL database commands can be given and sensors polled, or commands given to motor or servos. And any number of interfaces could be written for the robot.

One of those interfaces I would like to be an Microsoft Robotic Dev Studio service. Any thoughts?

I want to walk, and keep walking. (No pause) (Thu Mar 11, 2010 5:21 pm)

Thu Mar 11, 2010 5:21 pm (GMT 0)

Hi all.
I haven't been able to get to my Robobuilder recently due to many of life's other "distractions".

However, one thing that I guess isn't clear to me ... how do I remote control it to make it walk and keep walking until I either press a button or release a button. Seems for everything I've done it's walk, stop, press the button, walk, stop, etc. Even if I take the forward walk motion and copy it a bunch of times and play it, I still need to keep telling it to go again.

Is there a way that I'm just not seeing or thinking about? I see videos of other humanoids and they can be made to walk (or run) turn, etc with a remote and there's no apparent pause.

Ideas?

Thanks a bunch!

Hi -

It should work, can you post the extract of your code where you call runMotion ?

Also check you have the latest version of the dll http://robobuildervc.googlecode.com/files/RobobuilderLib.dll

and also check your firmware version is 2.23 or better

cheers
