Step 2 – Building chassis<\/h2>\n\n\n\n
I used hobby plates instead of plywood as I don\u2019t have a table saw yet. I started by building a main box. First, the side walls.<\/p>\n\n\n\n Yes, I know, there are better methods of joining walls to the bottom.<\/p>\n\n\n\n Inside walls for inner bearings and motors.<\/p>\n\n\n\n Second wall.<\/p>\n\n\n\n Painted chassis outside.<\/p>\n\n\n\n And inside.<\/p>\n\n\n\n I used UCS204 bearings and M20 threaded rods as axles.<\/p>\n\n\n\n The wheels come with bearings inside. The idea is to mount M20 threaded rods on the wheels so the axle can spin on the bearings.<\/p>\n\n\n\n The adapters for bicycle sprockets are cut out of MDF on my CNC router.<\/p>\n\n\n\n Adapter mounted on the motor.<\/p>\n\n\n\n Same story with the adapters for wheels. You can see there is a hole for an M20 nut. I thought I\u2019d try to force an M20 nut on the rod and secure it with locking nuts on each side. From a mechanical point of view, the idea should work, and it did. The only issue I had was the space around, which made it difficult to tighten the nuts<\/p>\n\n\n\n Adapter mounted on the axle.<\/p>\n\n\n\n Motors, wheels, and chains are mounted.<\/p>\n\n\n\n The chain in the picture is a little bit loose, but I fixed that by installing chain tensioners.<\/p>\n\n\n\n I am using the Graupner MX-20 RC system together with the Sabertooth dual 25A motor driver.<\/p>\n\n\n\n One linear actuator will be used for lifting, and two for rotating left and right.<\/p>\n\n\n\n It is time to test the drive system. The chains are making a lot of noise, but everything works as it should.<\/p>\n\n\n[mom_video type=”vimeo” id=”103018663″ width=”746″ height=”502″]\n\n\n\n The big moment. Test run. The batteries are a little bit flat, but I still could test the robot.<\/p>\n\n\n[mom_video type=”vimeo” id=”103018814″ width=”746″ height=”502″]\n\n\n\n After the test run, I realized that one bicycle chain driving all 3 wheels is not a good idea. Everything worked fine when I was driving back and forth, but when I tried to turn, the loads on the chain were too much, and the chain kept falling off the sprockets. I tried to tension the chains even more and tried several other tension solutions, but nothing helped. I could replace one long chain with 3 short ones, moving the motors to the middle and trying that, but at this point, I already had another idea. I was disappointed that the chains performed so badly, but at the same time, I was happy with the result. It was my first custom-made RC robot, and I learned a lot in the process of creating it. The first prototype of the 6\u00d76 wheel drive RC snowplow robot was scrapped, and I went back to the drawing board (SolidWorks) and designed a new one with custom-made belts. The design looks like this, but it will take some time before I build it.<\/p>\n\n\n\n A few years ago, I got the idea to build an RC Snow Plow Robot with an FPV camera, lights, and night vision. There aren\u2019t many of those out there, but a few videos on YouTube were enough to get me inspired. Of course, welding is not my best skill, so I decided to design […]\n","protected":false},"author":1,"featured_media":2857,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[70],"tags":[],"class_list":["post-2912","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-rc-robotics"],"jetpack_featured_media_url":"https:\/\/martinsentech.no\/wp-content\/uploads\/2017\/02\/rc-snow-plow-6x6-wheel-drive-v1.0-1704x1147-1.png","_links":{"self":[{"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/posts\/2912","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/comments?post=2912"}],"version-history":[{"count":2,"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/posts\/2912\/revisions"}],"predecessor-version":[{"id":3586,"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/posts\/2912\/revisions\/3586"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/media\/2857"}],"wp:attachment":[{"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/media?parent=2912"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/categories?post=2912"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/martinsentech.no\/index.php\/wp-json\/wp\/v2\/tags?post=2912"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/martinsentech.no\/wp-content\/uploads\/2017\/02\/rc-snow-plow-6x6-wheel-drive-v1.0-01-1024x576.jpg\")
