at the time I am working on a servo electronics for stronger dc geared motors
for the legs because normal servos are weak.
based on an arduino nano and a powerful h-bridge. can operate for motors up to 30A
the circuit is driven as a normal servo, the design is completed the circuit but the software not quite.
but unfortunately I have a lot to do…[Read more]

bicepscover printed with enclosure on the printer

Gael Langevin replied 8 years, 4 months ago

Well the enclosure makes a huge difference. That is for sure.
My printer is also continuously closed, with no fan inside besides for cooling the extruder itself.

bicepscover parts prited without enclosure

i solved the problem with printing bicepcovers with a quick and dirty solution, but i will build a woodenclosure for my printer

Gael Langevin replied 8 years, 3 months ago

I love when it is fully DIY , it is so much in opposition to the “SO” technical approach of a 3D printer.

i solved the problem with the right arm now so all potentiometers should be in the right position
i replaced teh rektangular one with a round one its better for finetuning.
i have spend much time in printing the biceps covers but i have some problems with this parts. the front covers now finished and o.k. but the side covers have tension cracks…[Read more]

Great! have you been able to set it as default positions following the recommendations I posted recently on the tutorial? It looks like it !
One question, you haven’t printed the bicep covers, is it because you like it this way?
Just to say, the bicep covers, once glued to the structure really helps reinforcing. It greatly helps avoiding…[Read more]

problems with rectangular potentiometer of the hs805bb+ servos solved
better solution we can buy the potentiometer separately so nothing will be done in the design
this is a examble for a german page where we can buy this
http://www.modellsport3000.de/cosmoshop/cgi-bin/lshop.cgi?action=showdetail&artnum=3-8120
it`s the same used in the old HS805bb…

so the problem with the right hand is fixt the servo now is in the right position but the problem with the rigt sholder neutral position need a bit time, make a new holder for a rectangular pot

so first steps with myrobotlab are done, thanks to gael for his help
but i have some problems with myrobotlab but i will ask at the myrobotlab page
when i make changes in the scripts i have to start the program new
so i save first, close the program start it again and open my file then everything its o.k.
the video is my first script

Thomas Wurm posted an update 8 years, 4 months ago

The fight with myrobotlab
after a few hours with installing the program and upload the sketches to the arduinos
and some problems to use the headpart finally i am able to controll all funktions with the sliders i am satisfied so far now i have to learn how the rest of the program works
and how i can save the settings and protect my nerves, lol

Gael Langevin replied 8 years, 4 months ago

You can use the settings with a script, see the settings for the hand
Here is a minimal script:

the servo was a MG 946
but it was a programming error in my arduino sketch, I did not use myrobotlab
got it just today installed and trying to find my way

Gael Langevin replied 8 years, 4 months ago

What servo did you use for the jaw? I have burned a few of them, MG995, MG946R, MG996R… The torque needed to action the jaw, and the movement repetition cause great stress on the servo. Bob Houston has been using a HS-311 servo since he started his built and says he never had to replace it.
Might be worth trying.
