Robots are crazy, is it right. What about making a robot which can be controlled by your smartphone, really cool.
In this project, we are going to build a robot that can be controlled by Bluetooth technology from your smartphone. For this, you must install an application so that we can transmit commanding signals from the phone to the robot easily. use the given below link to download and install App.
