Etch-a-Sketch Project Concepts

The video documents the creation of an Etch-a-Sketch camera robot, detailing the challenges faced in its development. The team engages in a circle drawing game, receives inspiration from a convention, and embarks on building a robotic picture sketch. They explore motor control, G-code integration, and calibration techniques. Despite setbacks, they optimize the design and achieve a successful demo, showcasing the robot's ability to draw complex images.

What was the initial fun activity that led to the idea of creating an Etch-a-Sketch camera?

• Drawing the best circle on an Etch-a-Sketch

• Building a robot from scratch

• Attending a science convention

• Watching a YouTube tutorial

What is the purpose of the encoder in the Etch-a-Sketch setup?

• To provide internet connectivity

• To read the position of the magnet

• To power the motors

• To display images

What does a feed-forward controller help with in the context of the Etch-a-Sketch project?

• Predicting actions before they are executed

• Increasing the speed of the motors

• Reducing the size of the Etch-a-Sketch

• Improving the image quality

What is G-code primarily used for in the Etch-a-Sketch project?

• To control the speed of the motors

• To convert images into a format the robot can draw

• To enhance the color of the drawings

• To connect the robot to the internet

What was the main issue with the initial square test on the Etch-a-Sketch?

• The Etch-a-Sketch was broken

• The image was too large

• The square was not holding its shape

• The motors were too slow

Why did the team decide not to switch to stepper motors?

• They preferred the sound of drone motors

• Stepper motors were too expensive

• They wanted to challenge their engineering skills

• Stepper motors were unavailable

What optimization technique was used to reduce the G-code lines?

• Genetic algorithms

• Traveling Salesman Problem

• Machine learning

• Neural networks

What is the purpose of using neural style transfer in the project?

• To enhance the speed of drawing

• To connect to the internet

• To simplify images for drawing

• To improve motor efficiency

What was the final goal of the Etch-a-Sketch project?

• To build a new type of robot

• To create a 3D model

• To draw realistic portraits

• To win a competition

What was the main challenge faced during the final preparations for the demo?

• Finding a new Etch-a-Sketch

• Optimizing the G-code quickly

• Building a new robot

• Creating a new software
