I’m an avid fan of the biped humanoid style of robots. So I’m going to add two cents to this topic. Functionally, the Kondo 2HV has more DOF (extra one in the head) then the Robonova and is actually cheaper then a Robonova. However, from a development standpoint, the Robonova has a great service record, and also uses metal brackets instead of the plastics that 2HV uses. The 2HV in my opinion is a much sleeker and much more capable robot then the Robonova. If you want to talk about the 1HV, which as an extra 2 DOFs, then it is only slightly more expensive then a 2HV. IMO, the 1HV is superior to the 2HV because of the hip rotations, but with the “hip rotation” mod kit offered by Kondo for the 2HV, the 2HV can be nearly as capable as the 1HV. I personally own a Bioloid Comprehensive kit, which I configured into a humanoid. I think it’s more capable then a 1HV, the servos are a lot stronger and has temperature, load, and other sensing mechanism built in… It has hip rotation capabilities, and comes with a AX-S1 sensor module, which has three sets of IR (front, right and left), microphone, and a speaker inside.
Now for a LM-based humanoid. I think the sluggish motions you saw on the .com site was due to the fact that it was using HS5645 servos. I used H645s on my biped scout and I can tell you that it is NOT capable of supporting the weight. The advantage of an LM, SES-based, humanoid is the fact that you can easily swap out the servo for ANY standard size servo. I think for the LM biped humanoid to be formiddable, the MINIMUM servo you would need are HSR5990TGs.
I think the demo videos didn’t do the LM Bipeds any justice, since I believe Jim put those together as a proof of concept and not to reflect on the programming possibility. Once you have the mechanical frame (SES brackets or otherwise), the electronics (SSC-32 plus botboard), enough torque (HSR5990TGs), “acrobatics” and fancy moves is a function of programming. Many of the biped humanoids that exists out there seems to have fancy moves is because they are “canned” with fancy moves, meaning that the manufacturers have worked on many of these moves meticulously.
Once you get past these “canned” moves, it’s up to you to feel satisfied with these, or develop it further. When I got my Bioloid Humanoid working with the default code, part of which includes walking forward, backward, turning (with hip rotation), while detecting obstacles, I was impressed for about 15 minutes. Although it took the manufacturers a lot of programming to get these moves going, I got bored with it after 15 minutes.
Now what keeps me going is to develop on top of the basic foundation laid down. What’s left to do is actually quite a lot, because my route isn’t an RC-based route. I want automatons, so this is where my journey begins with this humanoid biped.
I believe that when people look for a bot, any bot, humanoid or otherwise, you also have to look deep and ask yourself what part of the development you would like to start with. Robonovas, Kondos, Bioloids, all have many of the basic foundation laid down, so you take it beyond this. LM on the other hand starts from scratch, so the development is from the ground up, although because you have the LM community you are not alone.
Currently, I’m developing my CH3-R and Bioloid Humanoid. I think down the road, I’m going to go for a SES-based Biped Humanoid with HSR-5990TGs. I estimated the cost for it, it’ll roughly be about $2500 for a 19 DOF humanoid. But it’s $2500 for a high-performance, metal-bracket humanoid (just compare the torque of the HSR5990TG versus Kondo servos or Robonova).
What an essay, whew!!!
Edit: Forgot to mention this site:
robotservicesgroup.com/index.html
Possibly the most comprehensive site on comparisons of humanoids. Although it doesn’t include some of the newcomers like the Kumotek, Robovie, and etc, it is nevertheless an awesome site…
