Robot Micro Servo Arm

thingiverse

This is a Robot Micro Servo Arm that I want to use to learn about servo motors. Probably I'll be making the hole robot and this could be the left arm of that robot. I used 3 TowerPro SG90 servo purchase on dx.com (the third I thing I'll be using a grip or something. This are the specifications: Operating speed (4.8V no load): 0.12sec/60 degrees Stall torque (4.8V): 2kg/cm Temperature range: -30 to +60'C Dead band width: 4 usec Operating voltage: 3.5-8.4 volts Last picture is Version 0.1 I make a hole so I can pass the cable through and put the all together. Suggestions and comments are highly appreciated. UPDATE December 17, 2013 21:17 = I just uploaded a file that you can print out to have the Arduino Board next to one servo in order get stability. Also I put on the same file some washers that are useful to keep the rotating part of the servo in place. Also uploaded some pictures. UPDATE December 18, 2013 19:44 = Uploaded the file for the rotating servo attached to Arduino. Uploaded some pictures also. Has anyone used the files? UPDATE December 23, 2013 19:29 = Some pictures with the arm almost done. UPDATE December 27, 2013 17:51 = I got some servos to finish the arm. Put them all together and and just deciding which gripper to use. Uploaded some pictures. P.D: Sorry for my English. Instructions As I said before I used the Micro TowerPro SG-90. I had to unscrew the bottom of the servo so I could place the servo in without damaging the cable or even the printed part. I'll be using Arduino UNO to make the servos move. I'll provide the code when I have it. If you have any question do not hesitate on contacting me. Any suggestions or ideas?
