Children display innovative and eco-friendly ideas

~By Jyoti Singh

An app-driven automated food maker, an automatic dust lifting machine, a dustbin with sound alert, hand-driven waste picking and dumping cart, currency note sterilizing machine for ATMs, wrapper picker, cycle-powered road cleaner, a tiffin box that reminds children to wash hands before eating.

These are some of the ideas and models on display at the Child Innovators Exhibition which opened on Monday, May 14 as the part of the sanitation fortnight organized by the Department of Science and Technology (DST) in New Delhi.

Abhishek Bhagat explaining about his innovation

Abhishek Bhagat from Bhagalpur in Bihar has developed an automated electric-operated food making machine. One can chose a dish from a recipe list, along with the quantity to be cooked. The machine has different boxes for ingredients from where it automatically takes required ingredients and prepares the selected dish. It has the function of verbal instructions as well. Abhishek has also developed a mobile app that can control functions of the cooker.

“In my family only my mother used to cook and if she used to fall ill or had to go out then I had to cook. From there I got an idea, and I started working on this machine that cooks itself,” Abhishek said.

Another innovator Aarthv Sharma from Kullu, Himachal has conceived the idea of an innovative hygienic toilet seat cover lifting mechanism using foot. The basic problem with the western toilet is that the rim gets wet and dirty after use. It is unhygienic to use such toilets. So, he has placed a pedal adjacent to the toilet pot that pulls up the rim so that it gets dry. With the help of this mechanism, one can easily lift the seat cover without using hands. “I am further working on this prototype to put a slanting water flush system on the fixed rim so that it flushes the urine also,” he said.

Yet another innovation is remote controlled dustbin with wheels. Aditya Kumar said that his grandmother was sick and bed-ridden so he thought of developing a remote controlled dustbin. According to him, it works like a remote controlled car. The dustbin is fitted with wheels and can be navigated using a remote. He has made a mobile app for this.

Anju Bhalla, Joint Secretary, DST, said “these ideas coming from children are connected with real life and felt needs. While academic research mostly remains restricted to labs but these ideas have the capacity to make an impact on the society. These children have amazing potential and they have new ideas to solve day today problems.” The exhibition has been put together by the Ahmedabad-based National Innovation Foundation (NIF) which works with children and grassroots innovators.

Oppo is gearing up to introduce its Reno 15 lineup in India, with the series expected to focus heavily on enhanced imaging, performance stability and creator-friendly tools. The smartphone, which has already been launched in China, is anticipated to reach the Indian market in the coming weeks although the company has not yet shared an official date.

Expected price range in India

Industry estimates suggest the standard Oppo Reno 15 will fall in the upper-mid price bracket. While the Reno 15 Pro was launched in China at CNY 3,699 (roughly Rs 46,000), the Reno 15 base model is expected to be more affordable, likely between Rs 32,000 and Rs 38,000, depending on RAM and storage configurations.

Expected features and specifications

The Reno 15 series is expected to highlight Oppo’s improvements in sustained performance, camera capabilities and thermal management. Globally, the models run on ColorOS 16 and feature advanced cooling, particularly aimed at gaming and continuous live-streaming use.

For India, the upcoming Oppo Reno 15 is likely to offer:

A high-refresh-rate AMOLED display
Triple-camera setup with a primary sensor optimized for better low-light clarity
Secondary wide-angle and portrait cameras
Front camera with autofocus and AI-led enhancements for live streaming
Around 5,000mAh battery with fast wired charging support
AI-driven system optimization for smoother long-term performance

Design-wise, it is expected to follow the Reno 15 Pro’s flat-frame style, offering a slim profile, improved durability and brighter display output. With growing demand for creator-focused smartphones in the country, the Reno 15 is being positioned for users interested in mobile photography, vlogging and gaming.
