A Robotic Insect

Project title: A Robotic Insect

PROF. Math. Nijsten

Theresialyceum, Tilburg – The Netherlands

Introduction

Making an robotical insect

Two or three students age group 11-13 years. The group wil be 30 students. Therefore you have to divide the group in small parts. Two groups of 7 students and two groups of 8 students. Each group has once a week an other activity so you can concentrate the DBL on one small group.

Pupils are going to make an robot insect with some lasered, 3d print and garbage materials. The group will make small groups of 2 a 3 children and they will start with their own field study, to know each other by asking questions. This will be written on a A3 paper. The second step will to visualize these traits and hobby’s. Then they are going to explore for what kind of small robots or insects robot insects there are. This knowledge will be put on paper by a drawing with a pencil and colour.

Next phase is using Tinkercad and they have to draw an 3d model of the robot insect. The last step is to 3d print an laser cut some parts and make the insect in real life. One requirement is that it can move by themselves with a small motor.

Lesson3

Introduction Making a drawing of their own robot insect. They have now an idea of the insect robot they want to make and are going to draw everything they have put in words into a drawing.

Now you are going to make you own insect robot. Take a paper of 20 x 30 cm. Make your own robot insect with traits you just described. First, you will draw your robot.

You are working in a group and everyone should draw a sketch of a robot insect. Take the three drawings and together make one drawing of an insect combining traits from the first drawings. For this drawing you have to use colour. Write in the drawing how it works and what kind of

Time 50 minutes

Lesson 4

Introduction The drawing on paper will be made in Tinkercad. It will be a 3d model. In classroom you can show how to make an account in Tinkercad. First you will come in the lesson environment. For children in a age from 11-14 years this is very easy also you cannot save anything in this environment. Next you have to go to create the drawing board for making the drawing. Then I wil explain some basics in Tinkercad

Students can construct/make and test the circuit.

Students can reconstruct the circuit in to the robot insect

Student have the basic knowledge of electricity.

Extra Previous actions can be made with al materials you have. You do not need an 3d printer or lasercutter to make an robot insect. It can be done in the first stage and after that stage you can use the 3d printer and lasercutter to modify your design.

When you are making the circuit you can make first with materials from science lessons. Then you can explain how it works

Expert Advice
For some children it is to difficult to make an circuit. You can use pre assembled materials: http://nl.opitec.com/opitec-web/articleNumber/113794/zz/cID/c3I6Ym9yc3RlbHJvYm90Nw
When assembled you can use the part for intergrating it in your own robot insect.
