# Part 1 Construction and Experimental Modification 

Kommt von Klaus :) 

## Exercise 2 -  Kit-Modification Part 1 - Steering

This exercise focuses on modification of the kit for the autonomous vehicle that will accompany the entire course module. The constructed car forms the fundament on which the exercises are built and the acquired knowledge is gradually applied. Participants will familiarize themselves with the car already during the set-up and learn about its parts, features and sensors to implement the course objective: an autonomous self-driving car.

## Exercise Implementation

In this exercise, the smart car kit that was build in Exercise 1 by the participants will now be modified. The focus in this modification exercise is set on the steering behavior. The students are challenged to think critically about how to improve the steering of their smart car and discuss ideas as a group. 

### Exercise Preparation

Your group got a transparent plastic box with all the parts as listed above. Please label your box with your group name and the names of the participants in your group. 

Now have a look at the parts list. Make sure your box includes all the listed parts. In case of missing parts please inform the advisor. Please use the form you are given by the advisor to make sure your kit is complete.

Once you have ensured that all parts are included, please take your car and start to discuss your ideas in improving the steering behaviour of your smart car.

THIS STEP CAN BE IMPLEMENTED EXPERIMENTALLY.

The following model of the modification is presented as an example: 

The steering behavior of the smart car with 4 wheels has major disadvantages, especially in terms of turning and driving curves, resulting in a large turning circle. To overcome this drawback and improve the steering behavior, the two rear wheels were replaced by a single wheel that can rotate 360 degrees. This resulted in better steering behavior and a smaller turning circle, which had a positive effect on handling in curves.
