Week 6: Two motors = Two sensors!

I completed the license plate design and its actual prototype all by myself. I felt so happy! I designed it, chose the material, and by taking some assistance from Tommy and Ethan, I cut it using laser cutters. Then, using acrylic paints, I painted it. It started looking stunning! I felt so good after completing it!

This week was pretty fruitful for me.

One sensor cannot give out the values of the current pulled by two motors separately. Thus, there was a need for integrating two sensors to the end effector. But integrating and getting them to work wasn’t an easy task at all! Following is the circuit diagram which I made after understanding the ports and electric current flow. Patience and persistence always pay off! It worked.

I am now able to collect the values of currents properly. Using motor theory, I converted it to torque and then, by using tables, I calculated tension. But whatever the values of tensions I am getting are too much large. There is a need to go through the calculations and take a look at what exactly is happening.

I made one animation for 2D planar CDPR demonstrating the relation between the position of cable lengths. Now I have started working on a heat map for the simulation of the workspace.

I made a pretty big (comparatively big) projectile launcher for projecting anchors. I also got 3D printed two anchors which will hold the string and get stuck so that anchor points can be fixed on the wall.

I am aiming to complete the demo of the project by this Friday.

In the middle of the week, we all visited SWITCH, which is one of the huge data centers in the world.
