# newone www.open-ats.eu ## newone is a open-source, 3d-printed, low-cost vehicle controlled over mobile internet and programed in python Documentation, parts list, programs, newest versions at https://open-ats.eu/ [Demo video](https://www.youtube.com/watch?v=fuw2pRNdg8U)     [3D-Model vehicle](https://www.openats.it/3dmodel_main.html)     [3D-Model electronics](https://www.openats.it/3dmodel_elec.html)     [3D-Model print](https://www.openats.it/3dmodel_print.html) ## features: #### programs - programs for access the vehicle over the internet - program for controlling motors - program for videostreaming - open-source software, all programs written in python (focus on easy to understand) - programs using udp for low latency - opencv for taking video and displaying them, good for future AI - all programs can as well be used for standard rc-cars, airplanes or boats <br /> with PWM input and even for stationary surveillance cameras. #### 3d printing - open-source hardware, hole car 3D-printable - 3D-printed ball bearing (printable in one piece without any support) - 3D-printed flexible tires (airless, filaflex 82A) - insertable metal springs on all axis - assembly with only M3-screws and threaded brass inserts - support structures rarely required, low part count, easy assemply #### electronics - two individual servomotors to steer the front wheels - two individual brushless motors directly integrated into the rear wheels (inwheel, hubmotor) - raspberry pi - blheli32 ESC's (will soon change to B-G431B-ESC1) - 18650 li-ion cells with bms (25.2V) - low cost #### disadvantages - low torque cause of directdrive hub motor (will increase with planetary gear) - low torque cause of sensorless ESC (will increase with currentsensing ESC) - video stream consumes too much data
