Hey everybody, its been awhile since I built a bot, and I'm back to humanoids again lol. This is a cheap 15 DOF robot kit that I found on ebay. All the kit included was powdercoated aluminum brackets, screws, and those awesome aluminum servo horns. No instructions. So, I kinda built it my own way, with a layout similar to JD. I used MG995 servos because theyre cheap, metal geared, and (supposedly) 208 oz/in of torque. only the head servo gets its power from the EZ-B, all the rest get power from a Castle Creations 10 amp regulator. It's not enough. From what I read, these servos draw 2 amps each...gonna add more regulators later. Ok, enough chit chat, watch the video and lookit the pics!

Yeah, i figured the keychain would get ruined if it was on my keyring, thought it would make a better badge lol. Humanoids are difficult because of how many servos need to move together, i think thats why we dont see many here. The autopositioner is awesome, but it needs one more feature: the ability to change the speeds of individual servos from frame to frame. You can do that now, but it means bailing on the autopositioner and writing scripts instead, using virtual robot as a reference. Im getting it, but i dont wanna go too far with autopositioner before i have to start from scratch when i get my v4:)

Wow! Looks amazing @Kenny! Good job!
#44  
Even more surprising (or maybe not) is the lack of videos of any humanoid using the ezb (except for Kenny and JD).... Kenny how about a new video of the big guy doing something? C'mon guys lets see your humanoids in action...:)
#45  
That looks awesome! I agree- more videos! :D

great work.especially whit all those servo's.i made one myself.it took awhile before i got it,
wright all the servo's.

I like that walking gait on your bioloid:) all those dynamixels doing their job is just music to my ears:) I'll make another video for sure, i just need to make some more movements. All he can do right now is stand up from lying on his front lol. Might be a couple days, gonna spend some time on it tonight. Thanks for the kind comments:)

the head moves whit remote.a good way to center all servo's is do the off set not one by one but,
all at the same time.means unscrew all horns,do the off set then srew back on.

did you find a name yet? name (storm) maybe.

Havent used this bot in awhile, decided it was time to get some stuff done. It walks forward and backward with the new legs and i extended the arms by an inch and a half or so. Theres an accelerometer behind the battery in the chest. I wrote a script that polls the accelerometer every five seconds to check if the robot is on its face or back. If its standing, nothing happens. If its on its face or back, it stands up automatically. Heres a long walking video.

kenny

very nice walk.love it.
#55  
Nice Kenny. That looks like the way I walk after I've been sitting on the couch for a few hours. :P
#56  
the walking is awesome!
it looks like the legs were re worked to kind of resemble the Robi robot legs.
I love that lay out!
you should take a look at how they mounted the head with 2 servos they get very good natural movement out of the head. ill try to post some pics.

but again awesome walking motion.

any chance you can show us how you set up the accelerometer? please.
#57  
Looks great, have you gotten a V4 yet?
#59  
Glad Kenny could save the day!
My robot Dave has his new V4 and is being reprogrammed.
I need to get his camera installed in his head.
His has much more power now!

LOVE LOVE your robot and how he has come along.
I am new to all this, and really liked how yours has turned out.
Thanks for sharing.

Hi I want to know if you could share the project ARC of the humanoid robot DOF. I ask this giveaway I created the same for my seven year old son but I have no idea how to put the function. Thank you.
