two servo 996 tracked rover
Description
first idea was to design simple rover tracks without bolts and pins, and then i needed a rover to test them ;) i used dental floss to tie links together, the result is is flexible, reasonable easy to make and to repair when building a track, it is recommended to use drive gear or some other "device" to keep uniform space between links after some use tracks tend to stretch a little, so there is an additional part to rise a center wheel, you may scale the height as desired, in my case it was 4mm vertically servos are really slow at 5V Edit1: VAR 1: added a picture how too speed up a servo, it is not perfect but it works, one of the gears is placed between pinion gear and final gear and needs just litle grinding, (see picture: remove 1 and 2, place 3 upside down in place of 1) does not fit perfectly, but it works (how long?) Edit 2: VAR 1, after 5min driving on grass gears get damaged ;D Edit 3: VAR 2, printed gears, also not perfect, but it works (for now), no more driving on grass printing small gears with 0.4 nozzle is not perfect, you may consider cutting one of gears from old No.3 (i used nail clipper, curved teeths) gears were modeled in Fusion360 but real challange was to fine adjust them to print correctly (gcode for Anet A6 Marlin uploaded, PETG 250degC 70degC) Fusion360 file (initial/original and adjusted): https://icedrive.net/0/51S4vosWZW short video: https://www.youtube.com/watch?v=XC8wiyfScRo
