Gizmo is a robotic vehicle with a camera that can be remote-controlled over WLAN or the Internet by an Android app. The video capture of the camera can be watched online through the app. When in hearing distance, the vehicle can be controlled by voice.
The vehicle is driven by two NEMA 17 stepper motors. I decided for steppers instead of DC motors because they don’t need any regulators and allow to position the vehicle with an accuracy better than one centimeter per meter. An other advantage is their high torque especially on low rotation speeds. Disadvantage are the higher weight and higher power consumption. But in my opinion, the advantages make up these weak points.

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.
