There can be multiple approaches to demarcate the area: * Use transmitters to demarcate the area and make the rover aware of them to know when it reaches the limits * Use physical barriers that it recognises when it bumps in to them to demarcate the area (maybe a camera and a specific pattern on the barrier?) text/html 2016-12-06T10:57:43+00:00 https://nightowl.foundationu.com/projects:agriculture_bot:backlog:flexible_arm?rev=1481021863&do=diff We want an arm with better control and more flexibility to deploy sensors.

We also want to get away from the proprietary software that is required to program the VEX materials. Since we have the Intel Galileo available already, the therefore want to use that to control the rover. So we need to make the galileo capable of driving the motors of the rover. We need to investigate the characteristics of the motors and how to drive them from the pins of the Intel Galileo. text/html 2016-12-06T10:49:38+00:00 https://nightowl.foundationu.com/projects:agriculture_bot:backlog:obstacles?rev=1481021378&do=diff When navigating a real-world field/plantation the rover needs to be able to deal with obstacles. We therefore need to detect obstacles, avoid them and a adjust the navigation in a way that allows the rover to still monitor a large area. Tasks * Add a distance sensor to estimate distance to obstacles text/html 2016-12-06T10:44:27+00:00 https://nightowl.foundationu.com/projects:agriculture_bot:backlog:powersupply?rev=1481021067&do=diff To prevent requiring different battery packs or a wired power supply for the Rover, we need one single battery pack to run the rover. The Galileo required 12V while the motors run on 7.5V. So we need to create a battery pack of 4x 3.7V Li-ion 18650 batteries and use a 12V voltage regulator to feed that to the Galileo and a 7.5V voltage regulator for the motors (potentially). text/html 2016-12-06T10:59:09+00:00 https://nightowl.foundationu.com/projects:agriculture_bot:backlog:webinterface?rev=1481021949&do=diff We want to have a webinterface with graphs that allow the farmer to quickly see the data from the rover's sensors
