Arduino test with robot arm

Today was a big day, I finally got the new Arduino, unfortunatly it isn't the Uno that I ordered but the Mega. Well it means I can put even more servos in the beast!
So after waiting such a long time, now time for testing, because I had serious doubts about the strength of the servos Hitec HS 805BB. The piston I have designed is obviously something that use a lot of torque, if I could work out to make "supermodified" servos all my doubts would vanish. I have not enough electronic knowledge  for to do that yet. 
Anyway I was happily surprised when I first plugged the arm and saw that it actually pulled up the whole thing at once. 
It makes me want to go further in the design. 


Going to the next step
Building progress of the Left Arm.

Here the left hand is attached to the arm. Hitec Lenk Servo HS 805BB FG appeared to be a little bigger than I expected, so I had to remodel the brackets.
Here you can see that "leftrobpart4" had to be modified for the hinge
Sides reinforcers of the arm
"Robcap2" fixed to "elbowshaft1"
The left hand before it's fingertips assembly. This is something I am still unsure, because I would like to set some FSR sensors, but I have no idea how to make the servos responsive to them.


Inmoov robot hand

Building progress of the left hand. The main reason I'm building the left hand is because I sold away the right hand to DesktopFab. (I won't sell again, too much work, not enough time) And now, if I want to keep on fooling around with a robot, I have to rebuild the whole thing. It means, I will have to make another right hand. This also means it will be the fourth hand I will have printed and assembled. Gee, I could have made a octopus instead.

Left hand set up. Check well the position of the servos in their brackets.

Also look at the positions of the cable holders.

Use the side holes for to tight fit the servos. Notice the arduino support is set upside down in the left hand, this is for the USB connection and to adapt to the hinge/shaft of the elbow.
Here is "InMoov", the robot hand you can print and animate. You have a 3D printer, some building skills, This project is for you!!

This is a hand builded for a job (still picture commercial), it was supposed to be mobile but not animated and mostly be able to take human hand positions. Cables or fishing rods might be added in order to control it, but it was not the purpose of this work at first. I am now working on another model(for the fun), trying to animate it, I really would like to do it with computer control but I have never worked in that field. Never used servo's before, so any help is welcomed.
