Kondos KHRs

[daveski]

Hi all,

As I am newish to all this and wonder if someone could help me understand the difference betweent all the Kondo KHR bipeds.

e.g. KHR-1, KHR-2, HV, SP2.

I was thinking of buying a RN but I really wanted Hip rotation which I presume is the HV.

Any help, input or good links would be most helpful in my final desicion.

Many Thanks.

Daveski.

Actually it's kind of "none of the above". There are three robots currently in the KHR series-

KHR-1 - the original humanoid robot kit released a little over two and a half years ago.

KHR-2HV - the second generation of the KHR-1, released last summer. The 'HV' stands for high voltage (10.8 volts). Like the KHR-1, the KHR-2HV has 17 DOF.

KHR-1HV - a follow-on to the KHR-2HV, released at the end of 2006. It's often incorrectly written up in the press or on forums as having "hip rotation" - which would normally mean a single servo at the hip to allow the body to rotate. The KHR-1HV actually has two additional servos installed to allow independent rotation of each leg, giving it 19 DOF.

Thanks, that cleares things up a bit.
So I guess the latest incarnation (KHR-1HV) is the one to go for.

Just a couple more question.
1. What does SP2 mean as in KHR-2HVSP2.
2. How does the KHR-1HV compare to the Robonova which is another choise I am thinking about.

Thanks again.

One other difference is that KHR-1HV has the RCB3 instead of the RCB3J.

What the actual difference is I have not yet come to terms with.

1HV is relatively new so support is a bit more limited so far but there are a couple around and they share the same controller as the Manoi so their is help there.

Construction is quite simple, If you can't read Japanese, like me, get the english 2HV construction documents and genrally work from them. Comparison with the Japanese images for 1HV will show where the construction varies.

I've not seen the reference to SP2 before, where did you see that?

Thanks for that. I don't usualy read much of the instructions anyway.
Think I have been swayed towards the KHR-1HV, mainly because of the hip rotation as I think it makes a big difference to the movments of the robot.

BTW, does anyone know the best place to buy a KHR-1HV here in the UK?

Oh, and I found out that SP2 is service pack 2 and it was from the Kondo website.

Thanks again.

1. What does SP2 mean as in KHR-2HVSP2.

It's a software service pack - i.e. Service Pack 2 and includes some robot soccer motions for the KHR-2HV along with information on motion creation, remote control, gyro, and accelerometer setup, and a recommendation that the tub sole be used. It's available for download via the Kondo support webpage, along with an update that corrects some errors.

I bought mine through this site, couldn't find it cheaper elsewhere even with VAT....
