Robot car kit additions: U.S. mount, standoffs, and bumpers

thingiverse

These things are designed with Tinkercad. Edit them online: U.S. mount and standoffs: https://www.tinkercad.com/things/4pYk4dzTUIs Front bumper: https://www.tinkercad.com/things/j7IARV6cSri Back bumper: https://www.tinkercad.com/things/kUJ1W0sJkmt Circuit for sensing is also shown as Tinkercad circuit project: https://www.tinkercad.com/things/jznavQ265LV The Robot kit from Banggood is missing some parts. These are complementary parts. The U.S. mount helps to attach the US sensor to its base, and I added standoffs that can be purchased as instructed in the next video or info. Bumpers are used to add collision sensors on four spots: front, left, right, and back. Circuitry is used to detect which one is triggered using a single Arduino pin. The installation of these parts on my robot is shown in the photos. The Banggood kit can be found at https://www.banggood.com/DIY-L298N-2WD-Ultrasonic-Smart-Tracking-Moteur-Robot-Car-Kit-For-Arduino-p-1155139.html?rmmds=myorder&cur_warehouse=CN The US sensor HC-SR04 is included in that kit and can be found at https://www.banggood.com/search/hc-sr04.html A video explaining how to assemble this kit is available on YouTube: https://www.youtube.com/watch?time_continue=604&v=eKcKdMb_nkQ In this video, the US sensor is attached with a makeshift wire. This part makes it really secure, and standoffs are missing in the kit. They can be purchased or printed. I made five, using two for the motor controller and three for the Arduino.
