alseTv1 is an Arduino Nano based object avoidance robot which uses three HC-SR04 ultrasonic sensors in order to detect potential obstacles.
alseTv1 is the first iteration of a more sophisticated project which will make use of an additional Raspberry Pi in order to process signals from some sensors which already appear in the robot pictures, such as the Raspberry Pi Camera Module or an AMG8833 Grid-Eye infrared array sensor.
Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world.Main features
