Product Design of a 4 wheel differential drive robot

I have been thinking of creating a small mobile robot from scratch. From scratch means, go through all the steps of a product development. Design the overall architecture, design the circuits, make 3D model of the parts, 3D print the parts and finally integrate with ROS.

Inventory App for hobbyists

I used to buy a lot of small electronics component and sometimes store it for future use. The problem is sometimes it is hard to keep track of what you have in your collection. I find it hard to find any free inventory app that does the job. There are pretty good paid software, if you want to use it for some shops/warehouse etc. So I made an app that does the job. It is build using nwjs framework.

Raspberry pi based Car Infotainment system

Out in the market, there are a handful of car infotainment systems that you can buy for 10 to 30k INR. But nothing beats the thrill of making one from scratch and put it on your own car. So this is my effort to make one from the scratch.

Creating a Wireless remote for Nikon Camera using Esp8266

The Nikon DSLR camera I own does have a Bluetooth connection, but unfortunately it is of no use. You cannot trigger shots from Bluetooth. Also u can only share photos of low resolution across Bluetooth. What a shame!!! I also want a time lapse option which is absent in the camera. There is a WiFi option, but have to invest a lot more money to buy the WiFi adaptor. Fortunately it has an IR interface. So I thought of creating my own triggering device (like the ML-L3) which works over WiFi so that I can remotely trigger the shutter and also take time lapse pics.

ROS simulating a 3 axis robot in Rviz

In this tutorial, we will create an urdf model of a 3 axis robot and simulate it in Rviz.
