Robot Arm 6 degrees of freedom
« on: January 26, 2012, 03:08:12 PM »
Hi all
I think it's my first post here.
so i was wondering if i can get some help here,
I am building a robotic arm that has 6 DOF that copies the motion of my human arm detected by kinect , or a camera on laptop using MATLAB.
So i'm starting by the mechanical design,I'll be working on solidworks program but my biggest problem is that i can't imagine each part to draw it separately i only can copy a design so do you have any tips on how can i start my mechanical design?

Thanks A lot

First You need to decide how big/small You arm is going to be.

Start sketching base of the robot in solidworks with dimensions in mind.

Design each part of the arm from base going up, leaving some placeholder space for motors.

Think about material Your arm will be made of. Assign that material to relevant parts of the drawing.

Now, You should get fairly good estimate of how much each part will weigh.

Use parts' weights and expected maximum load to calculate minimum torque required, double it.

Find motors with desired specs. In motors' datasheets You will find drawings of them. Add these drawings as separate parts to Your SolidWorks model, and there You have it.
