Then we can just focusing on adding some idead we do have to it. We hope we will have to time to finish those ideas. We are experiencing some big problems with power connection. We are using some battery packs with 4 AA batteries inside each of them. This battery packs are not the best and we have had huge problems with these. We have probably soldering the connection to eachother a lot of times because the wires and the connection itself falls of etc. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"557\" height=\"1024\" src=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-half-557x1024.jpg\" alt=\"\" class=\"wp-image-6724\" srcset=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-half-557x1024.jpg 557w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-half-163x300.jpg 163w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-half-768x1413.jpg 768w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-half-835x1536.jpg 835w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-half-1113x2048.jpg 1113w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-half.jpg 1200w\" sizes=\"auto, (max-width: 557px) 100vw, 557px\" \/><figcaption>The arm withouth the claw<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-768x1024.jpg\" alt=\"\" class=\"wp-image-6723\" srcset=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-768x1024.jpg 768w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-225x300.jpg 225w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-1152x1536.jpg 1152w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-1536x2048.jpg 1536w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/3D-printed-arm-scaled.jpg 1920w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><figcaption>3D printed robot arm with the claw<\/figcaption><\/figure>\n\n\n\n<p>This is the final week of our project before our presentation and the individual talk next week. This project has been a challenging experience, but a fun one. We have learned a lot of eachother, and about making a physical system together. Things has taken a lot longer than we anticipated when first starting this project, but with this said we are happy with our project and what we have been able to make. This unmanned ground vehicle can be used to all sort of different tasks. We wanted to do more with the project, but we to little time we didn&#8217;t get to go thorugh with them. We have fulfilled our A and B requirements so we are happy with what we have manage to make this autumn. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/317298939_861574165037626_103465291824395437_n-768x1024.jpg\" alt=\"\" class=\"wp-image-7125\" srcset=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/317298939_861574165037626_103465291824395437_n-768x1024.jpg 768w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/317298939_861574165037626_103465291824395437_n-225x300.jpg 225w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/317298939_861574165037626_103465291824395437_n-1152x1536.jpg 1152w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/317298939_861574165037626_103465291824395437_n-1536x2048.jpg 1536w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/317298939_861574165037626_103465291824395437_n-scaled.jpg 1920w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><figcaption>Our finalized product<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-video\"><video controls src=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/316765558_5578200635626490_7260932389942220575_n.mp4\"><\/video><\/figure>\n\n\n\n<p>Mechanical <\/p>\n\n\n\n<p>The group wanted to make the arm out of plastic instead of plywood, the main reason for this is looks.

There are some but not as much as the laser cutter. 3D-Printing is a nice way to make a prototype of a product or a one-off part, but it is not suitable for series production. That\u2019s why I wanted to make the arm out of plywood in the first place. But for a project like this 3D printing is fine.<\/p>\n\n\n\n<p>The design of the 3D printed arm.<\/p>\n\n\n\n<p>Alle the work I have put in too the plywood arm made the modelling of the plastic arm easy. Because I could use the basic geometry to model after. Because I know the parts was 3D printed, I made the design as interesting I could but still functional. &nbsp;<\/p>\n\n\n\n<p>To make the arm a bit nicer I decided to hide the cables inside the arm. The way I did this is that I made a hollow cover that went over the engines and cables. &nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"457\" height=\"351\" src=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-48.png\" alt=\"\" class=\"wp-image-6984\" srcset=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-48.png 457w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-48-300x230.png 300w\" sizes=\"auto, (max-width: 457px) 100vw, 457px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-50.png\" alt=\"\" class=\"wp-image-6988\" width=\"414\" height=\"591\" srcset=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-50.png 605w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-50-210x300.png 210w\" sizes=\"auto, (max-width: 414px) 100vw, 414px\" \/><figcaption>Explode 2d view of Arm A<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"591\" height=\"539\" src=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-51.png\" alt=\"\" class=\"wp-image-6989\" srcset=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-51.png 591w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-51-300x274.png 300w\" sizes=\"auto, (max-width: 591px) 100vw, 591px\" \/><figcaption>Explode 2d view of Arm B<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"550\" height=\"735\" src=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-52.png\" alt=\"\" class=\"wp-image-6990\" srcset=\"https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-52.png 550w, https:\/\/dronesonen.usn.no\/wp-content\/uploads\/2022\/11\/image-52-224x300.png 224w\" sizes=\"auto, (max-width: 550px) 100vw, 550px\" \/><figcaption>Explode 2d view of Turret<\/figcaption><\/figure>\n\n\n\n<p>Some 2D drawings of one of the subassemblies, this subassembly is not visible when everything is put to getter.
