Tiny Tracked Truck - Inspired by Tiny FPV Tank/Tiny Trak
thingiverse
I took the chassis designed by Jani Kablin, and added a cab, so that i could use a servo controlled camera. I designed new sprockets, which can be used with 60x Lego 3873 Tracks. These are a direct swap, and use the same 8x4x3 bearings. The wider sprockets are for the bearings, and the narrow sprocket takes the servo arm hub, once the arm is trimmed off. Most of the electronics fit in the front, and the cab is hot-glued to the chassis. The VTX and battery in the removable rear cab. Electrics are 2x 9g continuous rotation servos. Frsky XMR. Matek 5v bec. 2.5g servo for camera pan. 9g servo PCB modified to control 3mm LED's. Modified/seperated AIO camera/vtx. Battery is a 2s 300mAh. EDIT: I have added a rear deck/load cover, which i had designed before the rear cab I've found that gluing pieces of rubber band to the tracks with impact adhesive makes them far grippier.
