Robotic Insect

Author: Agni Pachouli , Sofia Nikitopoulou
Summary of the Activity Plan

Students are challenged to design/construct and program their own robotic insect using an Arduino platform, electronic components and every day affordable materials. A servo motor will generate the movement of the legs, allowing their robot to move autonomously.

    LEARNING AND TEACHING

    Teaching Methods:

  • Experimentation
  • Exploration
  • Discussion, Presentation
  • HOW TO
    PHASE 1- INTRODUCTION & EXPERIMENTATION WITH CIRCUITS, SONAR & MOTOR
    Description: At the beginning of the workshop, the teacher presents the overall aim, the objectives of the workshop, the training methodology and the expected training results. A brief demonstration of the electronic parts (resistance, led), sonar sensor and motor is being held. Before students start acting, groups are asked to choose a name for their team.

    PHASE 2- CONSTRUCTING THE SKELETON OF A ROBOTIC INSECT
    Description: Students get involved in constructing a robotic insect by using every day and affordable materials (paperclips, wooden sticks, rope, glue etc). No specific pattern or instructions are provided, instead students use their imagination and creativity to choose and combine the materials. During the construction process, students exchange ideas, disagree, negotiate, experiment, try different ideas, collaborate and improve their construction. At the end of the session, each team will have constructed part of a unique robotic insect.

    PHASE 3- DESIGNING ROBOTIC LEGS
    Description: It's time to make the robotic insect move. Once they understand the programming part, they are challenged to find a proper position for the servo motor, as well for the legs, in order to make a functional autonomous robotic insect. Many questions arise at this point, especially regarding the shape of the legs, the position of the robotic legs and the position of the servo motor on the already-made robotic skeleton.
