This robot is one I built to learn. Before this project I did get my feet wet with a few small scale Arduino projects like an ultrasonic robot, (that would move backwards until it was a certain distance away from the wall,) and I did get to play with a few of the shields designed for the Arduino, but I had never built a full scale project with this microchip, or really, any microchip. I knew if I was going to continue on this journey of being a hobbyist I would have to fully understand the Arduino inside out. I wanted a project that would accomplish my goal, (or just get closer to my goal of fully understanding the Arduino,) and one that would be useful or fun to play with after completion! The project that would help me do just that was the Robo-Mobile.
The Robo-Mobile consists of two parts: a chassis and a robotic arm. The arm was designed to be able to pick up items, move them, and drop them in specific places. It was also designed to have a solid range of motion and should be able to move objects with reasonable weight. This arm would then be mounted on a chassis that can then move around like a car. Since the chassis was easier to make, I will be starting this Instructable with the chassis, and I will move to the robotic arm afterwards. This robot was built purely from scratch. (Okay, maybe not the motors, or the Arduino, or the wheels, etc. But no kits or pre-built robot arms or chassis are used in this robot.)

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
