(see demo video)</p> <p>I already use this off-road robotics platform for many projects:</p> <p>(autonomous solar rovers, Fpv crawler, long distance off-road exploration robot).</p> <p>I will eventually publish those projects too, but for now I’m working on making some documentation and assembly video to make this off-road robotics platform a “easy DIY project” for anyone interested in off-road robotics.</p> <p>If you have any question about the project, fell free to ask in the comment section.</p> <p>Have fun</p> <p>Nice feature:</p> <p>I use strings to link the differential suspension system instead of tie-rod or gear. This reduce the amount of moving part, so it also reduces the cost and the complexity of the rovers.</p> <p>Link for parts:</p> <p>( I put amazon link of product that have the same spec that the one I use in this off-road rovers platform. You can probably find some of those part somewhere else for cheaper and in the right quantities for the project)</p> <p>TT motor 1:120 reduction: <a href="https://www.amazon.ca/dp/B07DPNQMXS/ref=cm_sw_em_r_mt_dp_U_Mhf4EbDJ1WETF?tag=thingiverse09-20">https://www.amazon.ca/dp/B07DPNQMXS/ref=cm_sw_em_r_mt_dp_U_Mhf4EbDJ1WETF</a></p> <p>Motor Drive: <a href="https://www.amazon.ca/dp/B01KBTNHS6/ref=cm_sw_em_r_mt_dp_U_4qf4EbWX1NRFC?tag=thingiverse09-20">https://www.amazon.ca/dp/B01KBTNHS6/ref=cm_sw_em_r_mt_dp_U_4qf4EbWX1NRFC</a></p> <p>Batterie pack: <a href="https://www.amazon.ca/dp/B085N58SSB/ref=cm_sw_em_r_mt_dp_U_1mf4EbC9Z1HHV?tag=thingiverse09-20">https://www.amazon.ca/dp/B085N58SSB/ref=cm_sw_em_r_mt_dp_U_1mf4EbC9Z1HHV</a></p> <p>Hc-06 Bluetooth module : <a href="https://www.amazon.ca/dp/B00PJXG9NA/ref=cm_sw_em_r_mt_dp_U_Ynf4EbGFGWDBA?tag=thingiverse09-20">https://www.amazon.ca/dp/B00PJXG9NA/ref=cm_sw_em_r_mt_dp_U_Ynf4EbGFGWDBA</a></p> <p>Arduino nano: (you can also use Arduino Uno or Arduino mega) <a href="https://www.amazon.ca/-/fr/gp/product/B0816SGKHH/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1&amp;tag=thingiverse09-20">https://www.amazon.ca/-/fr/gp/product/B0816SGKHH/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1</a></p> <p>Arduino nano break out board : <a href="https://www.amazon.ca/-/fr/gp/product/B07YTZSR72/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1&amp;tag=thingiverse09-20">https://www.amazon.ca/-/fr/gp/product/B07YTZSR72/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1</a></p> <p>Screw 5/16-18 length 1in : <a href="https://www.amazon.ca/dp/B081F87WC1/ref=cm_sw_em_r_mt_dp_U_8of4Eb7AZ1PMJ?tag=thingiverse09-20">https://www.amazon.ca/dp/B081F87WC1/ref=cm_sw_em_r_mt_dp_U_8of4Eb7AZ1PMJ</a></p> <p>Skate bearing : (Od=22mm, Id=8mm, thicknes=7mm) <a href="https://www.amazon.ca/-/fr/gp/product/B07TWZ7X38/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&amp;psc=1&amp;tag=thingiverse09-20">https://www.amazon.ca/-/fr/gp/product/B07TWZ7X38/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&amp;psc=1</a></p> <h3>Print Settings</h3> <p><strong>Rafts:</strong></p> <p>Doesn't Matter</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>15%</p></div> <p><strong>Filament:</strong> amz3d PLA <br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>I use 1.6mm top, bottom(8 layer of 0.2mm) and vertical(4 layer of 0.4mm) shell thickness.</p></div> </p></p> Category: Robotics
