Toddler: Introduction to our Robotics project

“At Bottom, Robotics is about us. It is the discipline of emulating our lives, of wondering how we work.” Roderic Grupen

A descriptive video and final look of actual project is here —

After working on a my first Robotics project with a team, I’m here to share what we’ve achieved so far.

We studied about robots and how could we implement one. After having a weeks research and discussions we decided to use Raspberry pi as the central controller and features like remote control, camera feed, line following, obstacle detection and avoidance were short listed for the implementation.

It took us more than a month to implement these features in our robot.

Every day was fun working with various instruments, gadgets, and circuits. Every day our team’s routine was same and work was more sophisticated than the previous day. You need to be extra careful when working with hardware and micro computers.

About The Toddler

It’s a simple robot loaded with some features.

The toddler can be controlled wirelessly. You can play with it just like a remote controlled car but it is more than that. It can actively detect and avoid any obstacle on it’s way when running in auto mode, that means you cannot even hit the obstacle knowingly when running it in controlled mode.

A 5 mega pixel raspberry-pi camera module is mounted on top of it to view the video feed on our laptop screen.

It also features a line following sensor array to follow a black lined path designed on an even surface.

The whole software is implemented in python and we’ve learned a lot in the process.

Overall it is a good project for learning basics of robotics and opens up the vast field to explore the opportunities. Robotics has become a new field of our interests.

Here are few pictures of Toddler clicked while working on it.

In future we are planning to implement machine learning and artificial intelligence too.

It’s a open source project, so if you are interested in contribution and learning, feel free to contact any of the team member (Links given below).
