The KHR-1HV Chronicles

[grasshopper]

I see, however do I need to assemble the Robot in its totality or how do I check each servo individually? If so How do I check each servo individually? Any feed back is much appreciated.

it shows in the direction that you need to align the horns on the servos the easiest way I could think would just be hook all the servoes in to the controler board and power it up and get it to home position then put the horns on like it shows int the manuel... I shouls say that I am speaking from radiocontrol cars,boats, planes, heli exp my robot is stilling the mail....

err... this is all covered in the instructions - each servo is powered up and a position value set using the software app. before being put into the finished 'bot. There's no guess work involved - as long as you follow the instructions it's straightforward.

it's not quite like rc building where you simply power the servo to get it to center itself.

I've heard it said that one of the 1HV's limitations is that its KRS-788HV servos cannot be upgraded without using different servo brackets, yet in an article about Kondo's RCB-3HV controller upgrade, tempusmaster introduces an accompanying video with this blurb:

The robot is a KHR-1HV equipped with the new controller firmware. This particular robot also has KRS-2350HV servos installed in the legs, though that is not related to the controller update.

I'm wondering if the 1HV in the video has modified servo brackets or if the 2350 is a drop-in replacement for the weaker 788. True, the 2350 costs about three times as much as a 788, but judging from the 1HV in the video they definitely improve speed and agility.

here is the frames for 2350 servos:

Gosh, at 99,750 yen the 2350 conversion kit costs 80% of the price of the 1HV itself. (Although there's also a 2350 set below for 126,000, same as the 1HV.) Hardly cost-effective, but it's an alternative if cost is no object. Thanks for the info, Ray.

For a lot of the players here price doesn't seem to be a problem. Many of the ROBO-ONE and KondoCup participants are top level engineers or consultants and often have several humanoids they're working on at the same time. Dr. GIY is one of the best motor designers in Japan. Sugiura-san (Dynamizer) has his own consulting company that's well known for wind turbine design. Nao Maru (King Kizer) designs casting molds and automated equipment for one of the top 3 industrial valve companies, Maeda-san (OmniZero) works for V-Stone. Of course they don't spend money foolishly, but for them, it's not about being cost-effective, it's about being the best, and winning the competition.
