3D printed robotic arm

This is a project inspired by @andrias, We will try to print it and later edit the design.

Similar projects worth following
-This project is for learning how to deal with real 3D design.
-How to control the kinematics of this design.
- try to tacle the problems facing the original design& innovate more effective designs.

Today I started to:

- learn file extension types .ipt and .dwg

- downloaded autocad 2016 to view the robot design and got licensed.

- couldn't open because I needed inventor to view the parts and assembly files.

- got with @sai and sat a meeting to discuss our target

- viewed the forearm design with a360 online viewer and measured the dimensions.

- ordered the 3D to be printed (will decide tomorrow)

To do:

- get inventor, view the design, try to readapt the design.

- find other 3D printers able to get the original design.

- order the ball bearings, motors and nuts.

- keep track of the whole project.

Today,

We have installed inventor 2016 to our

Windows pcs so that we can view the design.

- we started reading and listening to Tutorials describing the main features of inventor 2016.

We set the target to reduce the current design to 80% of it's size now.

-Regarding screws and motors we will maintain them as the original design was too heavy to be powered solely by Nema11 and Nema 17.

- our next move is to keep learning about inventor and try to reduce the size of the design with maintaining the same size for the motors..

-another approach is to look for a bigger 3D printer that can print the original design with lighter materials.

I have completed the Inventor tutorial and heading towards editing the master design..

My plan is to edit the base items first and print them.. Then evaluate

End.

since there were a lot of problems in dealing with the x0.8 derived version of the original design in inventor, I had to think of another solution.

this solution is to create the NEma17 hole dimensions multiplied by the factor 1.25 so that when a 0.8 model is derived the dimension return back to the actual Nema dimensions.

the was another problem with the gears offset due to the change in the shaft hole.

I dealt with this problem by changing the screw joint locations by shifting the hole extrusion to the right by 0.224mm and upwards by 3.218mm.

I am to check the design and create assembly file.

I hold up the 3D print order till I am sure about the design.

the new dimensions and the assymply file of the new x1.25 solution will be up soon.

today I tested all parts of the first link and I made a lot of modifications in the design so that gears will fit the profiles and pins of the Nema17 will be in place.

I uploaded the new design and the assimbly file.

    today I successfully edited the motor extrusion and uploaded the scaled base-segment.ipt file and the base with the Nema17 motor.iam file here.
