Small Parts Automated Retrieval System

Problem Definition

SPARtS idea is to improve managing, storing and retrieving items from a workshop storage with several small parts.

3

4 of 24

Features

  1. Retrieve item bin from the storage via a text search system
  2. Retrieve an item bin by visual identification
  3. Store automatically several items with visual identification
  4. Visualize the current stock of each part
  5. Allows direct manual access of the user to the bins with robustness to incorrect placement of bins

Storage bin retrieval

  • Retractable platform for reaching bins
  • Movable platform in the height and width axis
  • Take bins ⇔ Lift from support
  • Return bins ⇔ Put down over the support
  • Keep track of the bins placement with their individual RFID tag

Item automatic storage

Method 1

  • Each item in a separate slot
  • Cleated conveyor belt
  • Visual identification
  • Hatch door opens and drops in the correct bin

Method 2

  • All items of the same type in different bins

DigiLearn

Table to learn digital circuitry hands-on.

Problem Definition

Table to facilitate workshop to high schoolers about digital circuitry and boolean logic on a hands on approach.

12

13 of 24

Problem

  • MUTEC (Museum of Technologies of UTFPR) is a project that stores and displays a wide range of electronic devices from across the last century
  • Receive up to 40 high school students from greater Curitiba
  • Can not accommodate all of the students
  • Other extension projects (PETECO) need to create workshops while a group of students visits the museum.
  • The workshops are unplugged, and should not need the students to have smartphones.

13

Solution

  • A teaching tool to use during these workshops and call students to the world of STEM ( Science, Technology, Engineering and Mathematics)�
  • Has the theme of digital circuits to teach and allow students to connect to this part of Computer Engineering.�
  • Has different pre-made tasks to allow the instructor to only think of teaching, and not creating challenges.�
  • Can be used by students and instructors intuitively.

14

15 of 24

The Project

  • 4x4 Digital Circuit Creator, With slots for 16 logic gates to form different circuits.
  • 8 inputs and 8 outputs, plus 8 special pins for different tasks.
  • Magnetic notches to easily connect each piece with the table.
  • RG LEDs to show the state of each stage.
  • Seven-Segment Displays to show inputs and outputs as hexadecimal values.
  • Magnetic cables do join gates easily.
  • Each gate is able to take up to 4 inputs.
