RB1000 running 3m Race with KHR2HV

[Ray offline]

I was looking for seeing who runs faster for long time, but lazy enough to find a place and arrangment.

well, finally I had made it in my holiday


Its a race of 3m long, RB1000 won the game and a little a bit faster than KHR2. He used around 15"67 to complete the course

Very cool!

Both of them stay pretty much on course. How were you controlling the direction? Any type of master/slave control?

The last video is hilarious! Exactly the type of behavior I would expect from a RB1000!

Although to RB1000 was quicker, i think the KHR2HV shown has a superior walking style. ie more human looking because, the feet are lifted higher.

Does anyone know if a realistic walking style/gait is a consideration in robo-one , or is it too early days to consider such things?

The actual criteria used by the ROBO-ONE judges during the demonstration phase have never been openly disclosed, though you can make some educated guesses based on the scores they hand out.

The fact that robots that have more realistic styles, like OmniZero, Dynamizer, and some others, always place near the top seems to indicate that it is important.

Hi,

well, I think this will be discussed in more details below:

you are right, I like the running motion of KHR2 too.
but in fact, both of their feet (toe) are lifted to around the same 1cm more.

but the back of the toe of RB1000 is lifted only a little, it be because the total weight of the Robot increase. (Because I replaced 6 higher weight metal gear servos; higher torque but lower speed too)

In fact, the main different is the seperation of the toes during running:

KHR2HV: 7cm
RB1000: 4cm

and KHR2's body is higher too (more attractive, and the trend of Japan robot design, I thing )

In conpare to original RB2000 product using the standard RBS581 Servo,
RB2000 lifts his feet much higher and much faster

But, the bad new, as I had previously reported before, the RBS581 servo is very easily to heat up and burn, so, my friends, if you want to have fun with RB2000 I recommended to replace the leg with min. 6 RBS5802 servos

(So, my RB2000 will have another mod . . . )

I would like to see a race with the KHR-1HV. My 1HV can move very fast

How about trying an RBT-1 doing the high speed shuffle - I know it's not a natural walking gait, but it's very fast and a bit more stable than lifting the feet and shifting. It's more like a human shuffling on a smooth floor with socks on.

Hi Droid works and cdraptor,

I would like to see a race with the KHR-1HV. My 1HV can move very fast

ya! I really wish to see your robot running, do you have a video?
Can you run the 1HV in a cabinet, it is higher than KHR2HV, I think the stability will have a bit lower

yes!, RBT-1 run really fast, but the disadvantage of this bot is he always (or nearly ) fall every time when you stop the running.

This may because it does not have a gyro.
or in more deeper, I do not found it has a conditional branch instruction for running loop. --- that I can push a decelation motion when I push off the button of the remote controller
( I have experience to program and play with RBT-1 but may not master enough )


Well, up to now, the most common Robot Kit that have the fastest servo speed is RB1000 (RB2000) and RBT-1 ........ 0.11 sec per 60 deg
and the actual robot speed will also much depend on the robot gait la

The hips make a big difference on the 1HV. Maybe 2x as fast as the 2HV because you have a more stability with 2 more DOF in the hips. I'm working on a fast walk on mine now. Almost a jog...lol Its a little clumsy right now but fast. I just have to tweak it and fine tune my gyros.
