The objective of this work is to build a cute little robot for my daughter. It could be a toy for her to play with, but my main intention is to let her have an early access to engineering knowledge and inspire her for future learning.
The brain of Smarty is a ESP32 Dev board powered by a 9V battery. It is programmed with Arduino. The Dev board and the power switch are accessible under the top cover, which is attached via magnets.
A remote controller comes together with this design. This remote controller has only one joystick. Another ESP32 Dev board is used in this remote controller and it is also powered by a 9V battery.
