Problem
When farmers grow crops, the have to deal with weeds growing on their fields in between their crops. To remove these weeds, pesticides are used. These pesticides can be harmful to insects, animals and humans and might even contaminate (ground)water. Clearly an alternative is needed.
Problem statement
In the current situation, a lot of pesticides are used in farming. These pesticides are used for treating bugs and diseases, but also for weeds. With the trend to be more environmentally friendly, we are looking for alternatives for pesticides and big farm trucks. A possible solution for this problem is a cooperation of small autonomous farming machines, which can control a field together. However, this solution is not new, people have already been working on the navigation of these small machines and on the detection of weeds in fields of crops. [1] That’s why we will try to make a weed picking device to be able to pick weeds without damaging the crops. For these small devices, we see future in the vertical agriculture as well, because they allow for a higher field density.
Objectives
RPCs
Requirements
- The system recharges autonomously
- The system must be able to differentiate crops from weeds
- The system removes weed from the farm field and collects it for disposal
- The system moves itself around the farmfield, following a predefined pattern unique for each farmfield
Preferences
- The system can operate for a long time before having to recharge
- The system should make minimal errors in recognizing weeds
- The system can work with 3D patterns, allowing applications in 'farm flats', reducing land area use
Constraints
- The system has to be more cost-efficient than human workers
- The system has to be intelligent, has to know what to do
- The system does never run out of power, has to return to the recharging station in time
- The system does not use pesticides
Users and other stakeholders
- Farmers
- Consumers
- Governments
- Society
Project setup
Approach
After reviewing the literature, we will determine the requirements for the system. Based on these requirements we will investigate implementations for these requirements and analyse their suitability. We will analyse the costs associated with a solution and compare this to the current costs of using pesticides, the effects on the stakeholders and on the future of farming. Finally we will conclude with a recommendation for or against the automated removal of weeds on farm fields without the use of pesticides and recommend future research topics.
