Secondary Students Design STEM Solution to Prevent Cycling and E-scooter Accidents in Tampines

A trio of students from Tampines Secondary, who developed a proposal to reduce accidents and mishaps between cyclists, e-scooter riders and pedestrians in Tampines, was awarded the first place in the 2019 Junior Achievement Singapore (JA Singapore) and J.P. Morgan The Schools Challenge – Live Smart @ The East in Singapore.

The winning STEM (science, technology, engineering and mathematics) solution addresses a growing concern in Singapore with walkways in many estates today increasingly crowded with pedestrians and riders. Joshua Kee, Caleb Chia and Arjun Subramani, representing team illumiKnow, developed a prototype demonstrating how installing solar-powered LEDs (light-emitting diodes) along the pavements of a HDB on Tampines street 42 can improve safety. With built-in sensors, the LEDs can detect oncoming cyclists and e-scooter riders, triggering the lights to glow and serving as a warning to pedestrians.

Held last Saturday (May 25, 2019) at Our Tampines Hub, The Schools Challenge – Live Smart @ The East aims to empower lower secondary school students in Singapore with STEM skills to develop sustainable, practical and innovative solutions for real problems faced by the eastern community. The inaugural program in Singapore saw 89 students from 24 school teams competing.

Finishing as first runner up was a team named Road To Victory, also from Tampines Secondary, represented by Ralph David Coronel Beltran, Thirumaran Kaushik Manian, Muhammad Yazrul Amry Bin Yazid and Dara Tao Yuyi. The team also focused on the challenges around the surging number of personal mobility devices on the roads and developed a device that can detect the speed of e-scooters and alert the riders when speed thresholds are exceeded. The device has an in-built sensor that monitors the rate at which e-scooter wheels turn.

Team Superllama from Pasir Ris Secondary – comprising students Liang Yu Syuen, Koh Hui Qi Angeline, Lian Jingwen Ashley and Leong Wee Kwong – which developed a smart device to limit water wastage in a household, was placed second runner up. Today, showers dominate water usage in a household, at 27 percent. Attached to the shower, the smart device uses a microbit as a sensor and alerts users with light (LED) and sound (buzzer) when a pre-set water limit is reached. The solution aligns with the vision by the Public Utilities Board (PUB) of empowering users to keep track of and reduce personal water usage.

Six schools in total took part in the challenge including Loyang View Secondary, Pasir Ris Secondary, Ping Yi Secondary, Tampines Secondary, Bedok South Secondary and Tanjong Katong Girls’ School. Students worked in teams of three to four under the mentorship of volunteers from J.P. Morgan and aided by Singapore University of Technology and Design (SUTD) student leaders.

The Schools Challenge is co-organized by Junior Achievement Singapore (JA Singapore) and J.P. Morgan, supported by Tampines Group Representation Constituency (GRC), Housing & Development Board (HDB) and Singapore University of Technology and Design and SUTD-MIT International Design Centre (IDC).
