So you're sitting in a room with your friend, and he wants something from you but you dont want to get up. So what's the best solution? A delivery car controlled by your mobile. Moreover, perhaps someone is stuck in debris in an earthquake or other calamity, and reaching them is not physically possible. What's the most handy, cheap and effective way of sending them a quick, helpful kit before the specialist comes? A small robot car that works via mobile control and can be used to transport the material to the victim through the narrow terrains.
A standard robot chasis can be used in the initial stage. It will be connected with motors to drive it. Motors will be powered by a 5v battery. SEEED motor driver/L293D IC will be used. Our robot will be connected to our mobile by using a Particle board. In our app, we will have commands for LEFT, RIGHT, FRONT and BACK. For easy movement and control, the mobile app will be easiest. In our chasis, a container / free plate will be mounted which will carry our subject to be sent to the one in need of it.
GENERAL BLOCK DIAGRAM:
Join the motors to our module, and the SEEED motor/L293D driver will be used to power it. Schematics of the circuit is attached below.
SCHEMATIC OF PHOTON
Our Ferrari can be controlled by the app of Particle or by the Blynk app. If we are using SEEED motor driver, then we can get a ready library of motor driver in Particle online IDE.
Now we have to program the Particle board in order to establish a connection between the Blynk app and the Particle Photon. This is accomplished by using the Blynk library which enables to create an easy and ready to go communication link between our device and the Photon.
The code can be dumped into the Particle board using the build.particle.io by signing into the Particle site. The code is in the attachments.
SEEED library is directly available on internet for DC motor driving.
As for motor driver SEEED or L293D, either can be used with Particle.
This car is specially designed for temporary and cheap aid as well as domestic use in house/hostel. In the future, in case of calamities, it can be used to detect people and the presence of dead/alive person in debris using Walabot. A camera can be attached to know the live feed of region where reaching physically is not possible.
