[nicolas gomez]

Hi!

Here this my modified robobuilder to update from 16 to 23 degrees of freedom,using original parts of Robobuilder 5710K,I have added more WCK servos,

1x Head WCK 1108
1x Neck WCK 1108
2x forearm WCK 1108
1x waist WCK 1111
2x Hip WCK 1111

placed of different form to the metal kit in other post explain like it assembe.

Amazing work!

The work in the head and hip is amazing.
I'm a bit intrigued how you managed to assemble the hip servo...

One of the cool things is that the robot looks fairlly proportional in terms of the length of legs, arms and whole body despite the many additions.

I have embedded the you tube video directly here:

Hi nicolas

I have embedded this new video in your post as well (I hope you don't mind that I edited your original post to embed the video).

The work you've done looks amazing.

I see there was a lot of custom fabrication.

With regards to the hip, I see you used your own metal parts.
Did you use any part of the Hip Pivot Kit we sell here at Robosavvy or did you just fabricate the whole metal part from scratch?

Hello Pedro !! again thank you very much for integrating the video, since I do not know how do it.

I did 4 metal pieces (aluminium of 2mm of thickness)

For the hip, place the 3 wck servos aligned, the central servo moves the torso of the robot therefore his axe looks up whereas the axes of servos of the sides look below(down) ,to make to turn every leg, the piece that joins these three servos was done by me placing the 3 sevos on a paper(role) of cardboard, then mark the position that was occupying each one , I advise to leave a space of 2 or 3 mm between(among) servos to be able to spend(pass) the cables, then use this template tu cut the aluminium.

To attach the hip with the leg use the jonit number 12, cutting these to obtain same squared form as like the jonit 5 preserving the alignment.

y make another two pieces to joint forearm and the arm

just found out that Nicolas actually uploaded some nice pictures of the bot and some instructions on how to do the chest modifications

The first photo describe how place the servos of the head and neck, inside the chest cover of the roobt-

The second poto show how place the aditional servo for the forearm,

The third show how jonit the waist with the RBC-BOX.

And finally for the hip, place the 3 wck servos aligned, the central servo moves the torso of the robot therefore his axes looks up whereas the axes of servos of the sides look below(down) ,to make to turn every leg.

The piece that joins these three servos was done by me placing the 3 sevos on a paper(role) of cardboard, then mark the position that was occupying each one , I advise to leave a space of 2 or 3 mm between(among) servos to be able to spend(pass) the cables, then use this template tu cut the aluminium.

To attach the hip with the leg use the jonit number 12, cutting these to obtain same squared form as like the jonit 5 preserving the alignment and the center alignment.

y make another two pieces to joint forearm and the arm that describe after

Very nice.

How is the knee and ankle servo dealing with the extra weight?

How about some walking with the next DOF?

Hi Nicolas

We've just received an email from Robobuilder about your work

They are apparently following it and sent a reccomendation: if you add Metal Joints to the robot you will get much improved stability in the motions.

In any case, we found it quite interesting that they follow our forum and your work!

Regards
Robosavvy

HI!!

Thanks for your interest and comments, now in the video can not be seen in the detail, but I already have added metal joints.

The instability seen in some movements is because I've been modifying the PID parameters of the WCK modules and so far I've picked up the Work Related software with motion builder.

amazing!!!
i was going through the pros and cons of the robobuilder and bioloid but after seeing this beautiful machine i know the robobuilder is for me.
did you not like the metal brackets and chest plate for the robobuilder????

do you still use the standered controller or a different one???

do you use it in competitions eg robo football or fighting?????

how quick does it walk and side step?????

sorry about so many questions just really intereasted
