In about month and a half , we finally came to the stage of moving forward with building of our IOT device. Our equipment have been delivered in February. Just to be clear here we are trying to build a personal assistant car with sensors attached and raspberry pi governing it.
Before starting to build an IOT device we need to equip the lab with a monitor, keyboard , mouse and a VGA to HDMI converter (if required) since raspberry pi has just a HDMI port. Connect all of them together and use Raspberrypi as a CPU. And connection on raspberry pi looks like this:
Here mouse and keyboard are connected to raspberry pi with USB port, there is a small port for power plugged in and finally monitor is connected through HDMI port.
Our first step is to built the car. It is similar to building a Lego. Let’s get started:
- The parts of car are delivered by Adeep Electronics.
- It comes with all screwdrivers, screws, base of the car, tires, wires, axles,nuts and brackets.
- We followed the Manual-PiCar-B-V1.0.
- Initial step is to put together middle large part of the car with all the screws.
- It holds cylinder, bottom two parts attaching the tires, top screen.
- To prepare the middle part, it needs hold copper standoffs.
- Once the middle part is ready prepare the bottom to parts for front and back.
- Both the bottom parts shall hold tires while fixing it to the middle part.
- Structure would look something like this:
So now when we have the basic structure of the car at hand , we are going to connect sensors to this little moving creature. Our sensors consist of a camera and a hearing device. We need to put all of these together and believe me it moves like a human head. So the combination of sensors will look something like this:
Yes, its is bit tricky to put them all together. Try to place the sides carefully so as to allow the movement of camera and hearing device. Now place this pretty combination over the thing with wheels. and the final product should look like this:
Further development of the device will be carried out in upcoming article- Making of an IOT device – Part III
