- Motivation of PA Agro chemicals -> water pollution, declining biodervisity, herbicide resistance limited natural resources and land -> nutrients, water climate change
- control traffic farming 1. run heavy machininery in track -> less soil compaction -> better yield -> well designed farm layout 2. standartisation of equipment annd field layout -> requires GNSS -> weel cenrte -> spry boom ...
- variable rate application aplly diferent amount of fertilizer at different parts site specific management Apllication type and applicatin sensor/map
- application type what action are we taking on the field -> variavle speed seeding -> varibale rate weed control -> variable reed fertilizer
- application sensor/map tells us how to take the action -> generally action in always taken it is usually informing the system whether to aplly more or less -> pre defined map -> on the fly using sensors -> cpmbining pre defined ...
- what can we achieve with sensors and technology? - Automation works well in structured evironment -> programmed where to go -> can't cope with change - sensors allow us to make better sense of our environment -vison is an impressive sense -> we ...
- what is a robot? elctro mechanical system that can interact with the world has some levels of automation -> remote control: execute a range of actions based on input from external source -> artificial intelligence: ...
- what's the physical design of a robot? Actuators -> enables the robot to interact with teh envrironment (Motor to move the weel) Physical Component-> way the robot interact with environment is often noisy or imperfact Environment->environment ...
- how do we define the robot? electro-mechanical systems-> actuators environment in which it operates tasks that it needs to undertake sesnsors that it uses
- what specifications do we need to design a robot? singe function specifications operational specifications technical specifications
- what are the singe function specifications? autonomous movement navigate trough the field saftey spraying with herbicide lightweight sensing to detect and classify plants energy efficient alternative method for weeding
- operational specifications muts be transportable bewteen the fields using standart machidnery must be able to shutdown operation and stop the machine if it's close to a human map of the field with the herbicide usage and weed ...
- technical specifications vehicle mass payload mass operational speed: maximum speed vehicle and boon dimensions vehicle steering configuration External considerations costs format of the environment expected weed density ...
- which sensor types do you know? point sensor line sensor area scanner
- describe the point sensor 1 pixel cheap to produce often used to capture multi-spectral or hyper spectral information detect vegetaion in a region suing NIR and RED if there is vegetation than spray herbicide (WeesSeeker) ...
- Describe the Line Scanner W pixels often used to obtain multi-spectral or hyper-spectral information can form an image by moving the sensor (need to know how the sensor moves) pack houses to dedtect defect (very fast, the object ...
- function of an image sensor? each pixel can correspond to multiple wavelenghts -> a pixel is the response at a physical point in space -> the light is accumulated to give the strenght of the response -> often conferted to a number ...
- describe the Camera area scanner WxH pixels abe to capture an area very quickly ubiquitous sensor find crop in an image classify the species of a plant in the image estimate the amount of vegetaion in an area (vegeation coverage) ...
