KHR-2HV !!!

2006-06-24T17:16:50+01:00

Here's another picture of the KHR-2HV with knees bent side by side with KHR-1. Note how the KHR-2HV's knees have been re-architected for a more stable low pose which probably helps in Robo-One combat situation.

If you want to change the setting for the servo you need USB-ICS.
You use this interface to change the setting.
RCB-3J does not support to change the setting for the servo.

Thank you!!

To do advanced settings for the servos do I need to buy a extra USB-ICS interface or can I do it through the RCB-3J?

official reply from Japan:

Code:: If you want to change the setting for the servo you need USB-ICS. You use this interface to change the setting. RCB-3J does not support to change the setting for the servo.

Good comparison photo.

Do you also have the side view that shows both of them crouching down as far as possible? The leg geometry is drastically different enabling the KHR-2HV to bring it's COG way down similar to the Robonova.

The original KHR-1 couldn't get down that far which is a big disadvantage during the fights in the ring. 8O

Yes Ray, you have to redo all the movements.
That's because the robot will be taller, heavier, and the geometry and balance will all change.
I will have to shoot new photos for a frontal view.
The problem is that i'm on tour right now and won't be back for 2 weeks.
I'll let you know in this thread when a frontal photo is available.

Great! Meltdown

Well done, just simply 2 servo! no kit is needed!

But I have 2 question, hoping you can tell me:

1) after your new 2DOF for the leg, necessary to adjust the movement
in scenario ?

2) I think there is a little "shift" in the upper leg,
Can I have a look of your KHR in a "stand-up front view" position?

Much thank you !!

My KHR-1 has rotating legs and arms.
(see my photo gallery http://robosavvy.com/Builders/Meltdown/0.htm
Just buy the extra servos needed and get creative.
Nothing to it.
You can do the same with the RN1

Don't like the plastic at all.
Don't like the change in voltage, my RK2 gyros won't work.
I'll rather buy stronger 6v servos if need be.
I'll keep my khr-1 version1 thank you.

By the way, KHR-1 has a 2DOF Chest kit, i.e. the two legs can be rotated!
I think KHR-2 will sooner has,

ya, I am also disappointed,

I don't like the pastic, it down grade the robustness of the body, although it get lighter weight. Pastic will crack in some day (agenting)

Anyway, good things are:

1) Combining 2 controller into 1 controller (RCB-3J)
2) flowchart can be used to program the KHR-2
2) LED and Sound can be program
4) 3 ANALOG input ports that can accept gyro and programed in flowchart
5) USB connection to PC

I don't know whether these PCB can be applied to KHR-1 or not [/img]

aaargh...thats disappointing

I am frustrated with the RN-1 because of this very reason...you cannot turn or change direction while walking in a seamless and natural manner. The robotis bioloid can do this...

For me - this is a deal breaker I know the new KHR has advanced technically...but without that range of motion that I want - it has not really moved forward

In that respect it's the same as the KHR-1 with one servo for the head, 3 in each arm, and 5 for each leg. Some of the dimensions have changed, probably because of the servos, and the foot/soles are larger. No leg 'rotation' in the sense that I think you mean though.
