Google Assistant controlled Robot using Bolt Iot

Ever built a robot that could be controlled with Wifi. Using the API for servo control by Bolt IoT. We can control a robot easily with IFTTT and google assistant.

refer to the video below

Note: This project is still under development, bugs will be visible. Also, a larger servo can be used (since micro servos are designed to support very small weights).

In this project, thin cardboard and paper were used to minimize the weight and increase the efficiency of the servo.

If you are good with papercraft. You might already know how to make a paper cube.

here is the design of the robot.
