^* The current division of task is a rough estimate for the next 7 weeks. New tasks may pop up or task division may be rotated, and is hence subject to change during the progress of the course.

Approach

The problem will be approached by a design question. What is the best design for a robot to combat deforestation which will be build modular so that it can be implemented for other purposes with minor changes. The first 2 weeks the approach will primarily be sequential, as user analysis, use cases and requirements/preferences/constraints need to be done sequentially before the rest of the project can start. Once this is over, the project will run in a parallel fashion where building and modelling will happen simultaneously.

Literature Review

The patent on remote control systems granted to Mitsubishi Electric Crop. By the US government. This document is a thorough description of how remote control systems work, if we decide to make our vehicle remote controlled all the info we need is in here. But it is incredibly lengthy and written in a way that is not pleasant to read, so use it as a last resort. https://patentimages.storage.googleapis.com/eb/4b/ce/ba560b94ae5c1a/US5554980.pdf

This 2 page article is a statement from Elon Musk, CEO of Tesla, about his predictions for autonomous cars in the near future. It shows his vision, which is directly linked to his companies (one of the biggest on this market) vision. http://www.oharas.com/ET/elonmusk.pdf

To get our car driving smoothly, we will probably utilize a remote control, meaning that it will be very closely related to a remote controlled toy car, to which this doc. is the current active patent. It shows the state of the art radio controlled toy car technology currently available. https://patents.google.com/patent/US4457101A/en

A guide to help us control a servo motor with our computer, as a servo motor is the most likely option if we want our car to drive without outside help. http://www.instructables.com/id/How-to-Dynamically-control-a-servo-or-motor-throug/

A short article on the workings of servo motors, the main two interesting reads are the control of the servo and the different types, as we will have to chose one if we opt to use servo’s to drive our car around. https://www.jameco.com/jameco/workshop/howitworks/how-servo-motors-work.html

Even though this site is a webshop, and not a scientific article, it shows what technology we can buy within a respectable price range and thus shows what we do not need to make ourselves. Before we start thinking about how to make a part of our robot, lets first check what this shop has got. https://www.tinytronics.nl/shop/nl
