Obstacle Avoiding Robot

cults3d

Having made the robot a while ago, I decided to make a 3D-printed enclosure for it. This is the result. Below are the parts needed to build the robot - Arduino Uno (or equivalent.) HC-SR04 Distance measuring sensor L293D Motor Driver shield SG90 Micro servo DC 3 – 6v gear motor and wheel x 2 Universal wheel 9 v battery connector 9v battery M3 screws, washers, and nuts 0.25mm copper wire Dupont cables – Female to Female You can get the code to operate it from - https://theiotprojects.com/obstacle-avoiding-robot-using-arduino-and-ultrasonic-sensor/ I changed the build slightly from the above, by using a 9v battery rather than 6 x 1.5v batteries. I also connected the motors to M1 and M2 on the motor driver shield - if you do the same, don't forget to change it in the code. If the M3 nuts are a bit loose in the robot body, they will need to be glued in place.
