DIY Wireless Robot Controlled With Your Smartphone

Figure 1: Wireless robot is controlled by your smartphone

The project aims to control the movement of an untethered robot by just pointing your smartphone at it. You can control the direction of robot’s movements by just leaning your phone forward, backward, sideways, and so forth. The most important application of this technique can be on chairs of disabled people. They can move around just by moving their phones or giving them voice commands.

The raw materials required for this project include a Arduino UNO & Genuino UNO, a 1Sheeld (Android shield for Arduino), a Cypress PSoC 4 Motor Control Shield, a Dexter Industries GoPiGo Robot Base Kit, a Li-Ion Battery 1000mAh, a USB-A to Mini-USB Cable, a Male/Male Jumper Wires, and an Android phone.

The first step is to mount and adjust the 1sheeld. You can check out the details here. Now mount the Motor shield over the Shleed. In order to burn the code, connect the Arduino board with your PC.

Once the connection is established successfully, move on to connect the two terminals of left side motor to OUT1 and OUT2. Now repeat the same with right motor. It is time to connect the batteries, now set up connection between red wire and VCC and black wire and GND. Now scan for your shield and select the Orientation shield, text to speech shield, and voice recognition shield.

You can now lean your smartphone forwards and see that the robot will move forward. The text to speech shield will warn you if you give the wrong order. It will directly speak up “ please give the right order. “ Further you will see notices over your smartphone on the Orientation Shield.
