the first project idea was

The sketch can be see in Principal and practices assignment

In few words, the first idea of my final project is a self-watering smart vase for small plants.

Sketch of the First Final Project

After defining the initial scope, I drew the first sketch

The CAD of the final project was done in the Week 03 assignments. BUT...........

Image5 - Time for Change

MAYBE it was a crazy idea to change the final project, but all today innovations were a crazy idea in the beginner, so....

I changed to the robot hand

What tasks have been completed, and what tasks remain?

New Sketch of the Final Project (robotic Hand)

My planning was at least meet the requirements to final projects

I’ve almost finished the assignments, missing now only the evaluation updates and followup questions.

I finish all the schedule in time and present to Neil in 2021/06/14. And everything was fine, Neil like the project.

What’s working? what’s not?

Everything was working fine, but Neil ask to organize the electric wires of the Robotic hand. I will improve this using some cable organize. I looked for a hand glove but I couldn’t find it here in my city. Probably because it’s always summer here LoL.

What questions need to be resolved?

I need to improve the user interface and in the future make the PC or a celular app to control de hand using internet

What will happen when?

Since the presentation already happens I will now improve my documentation. I need to check all the week activities using nueval as a guideline.

I will in the future develop another hand to make then play together and control then using internet

What have you learned?

This is a VERY important question. I learn a LOT about how to make (almost) anything.

I started to appreciate the soft skills developed throughout the course. They were one of my big motivations to take this course and I truly believe they were fulfilled.

It is very nice to see all the possibilities that are open now. I learn to use a lot of software and hardware that will improve a lot my career as a University professor.

Learning how to document project development as you go was a big challenge. It is very hard to use spiral development to document and do the weekly assignments.

Another interesting thing is how work adds up and becomes a lot if you keep doing little by little every week. I always struggled with keeping focus and motivation with a project. But the final result was worth all the troubles.
