Athletic Rollercoaster

Medical Fall Detection

Project Overview

A unique amusement ride that enables a user to navigate a track in a variety of directions using only their own physical effort and gravity. The system utilizes a compact, custom 3D-printed design that provides traction and grip on the track.

Rollercoaster "Cart"

The “cart” for the rollercoaster is held by the rider, one in each hand and one attached to each foot.

The cart body is fabricated from 3D-printed PEEK, a high performance thermoplastic.

Internal springs provide flexibility for smooth turns and support continuous traction via bearings.

Main detection Module

The infrared thermopile array sensor identifies a person’s activity through thermal heat mapping.

A convolution neural network algorithm was trained to detect  falls with 95% confidence. 

The MDM is WI-FI connected to a cloud server, which is connected to the monitoring interface.

Rollercoaster Track

The lightweight cart body fits inside the track, with a safety harness above providing additional safety for the rider.

One-directional bearings lock in reverse, preventing the rider from going backwards on the track.

The friction between the pitch rails and the bearings creates traction, enabling the rider to climb forward.
