    Research & Development Project  

There has been a growing demand for train-themed restaurants in our city of Hyderabad, and the entire setup was manufactured in Germany. Seeing this, a retired military officer who is a friend of our college's chairman suggested that we build our own train and tracks which served food. In response to his request, The department of Electronics and Communication Engineering chose an assistant professor and me to create a proof of concept on an industrial scale as a Consultancy Project.

​

We took up the challenge and investigated the actual working model in the restaurants. Based on our observations and to improve the existing model, we decided to make the system wireless by integrating an app. And thereby, we are developing this model using emerging technologies such as RAPID PROTOTYPING (Additive Manufacturing) and the Internet of Things (IoT).

                Working Video 

This is a working video entire model with train and tracks which has 3 paths (1-Straight and 2-curved paths) with a bogie and a load up to 1kg which is controlled by an application called Blynk IoT which is available in both IOS and Android systems.

Here are a few clips of working locomotives pulling weight on their bogies. The electronics are embedded in the train's front section and are controlled by the Blynk IoT application.

Pictures of Train and Track 

This is a collection of trains, bogies and tracks.  The engine was created and rendered using the SOLIDWORKS and Ultimaker Cura software. The segments are 3D printed with PETG material and then assembled. The bogies are constructed by laser cutting acrylic. We created wheels using CNC Lathe machining. Regarding the track, it combines aluminum metal laser cutting and rapid prototyping at the junctions.
