REDMOUSE.AI STRIDE LAB
Wearable Robotic Mobility Simulator
SIMULATION RUNNING BEHIND THIS SCREEN
A research project to build a walking-assistance device
STRIDE LAB is a research project by redmouse.ai. Its goal is to build a wearable walking-assistance device for people living with ALS or with other neurological, neuromuscular or musculoskeletal conditions, injuries or disabilities that affect walking and balance. The device is a belt worn at the waist with four articulated legs on motorised wheels and two telescopic stabilizers. It walks with the wearer, helps keep their balance, steps over kerbs and small stairs, and turns into a seat that supports them and can roll on its wheels.
What you see behind this screen is the device's digital twin: the simulator in which its control software is developed and learns to walk.
Also available: the Gait Analysis Lab. Registered users can use a fully working gait analyser that processes walking videos of patients automatically and securely: the video is analysed in the browser and never stored on the server, and the motion data is kept encrypted.
If this project resonates with you, or you feel excited about it, please consider helping us make it a reality in these three ways:
Your kind donation
How we will use the funds: the project is in its first stage, design. In this stage the device's digital twin (the simulator running behind this screen) is fine-tuned and learns to follow the wearer's movements, compensate for instability, improve their balance, and avoid or step over obstacles.
Mercado Pago (Argentina)
In pesos, with your Mercado Pago account or a card. You pay on Mercado Pago's page or app: no payment details are entered here.
Charged every month by Mercado Pago until you cancel it in your Mercado Pago account.
⚠️ Sending through any other network may result in permanent loss of funds.
Keeping this simulation running
Keep this simulation running in your browser or phone for as long as you want: the model learns how to move the joints and wheels to go around and over obstacles, keep a better balance, and more.
Every 20 minutes, anonymized training outcomes are uploaded to and downloaded from a secure server, so the knowledge is shared among all the instances run by contributors like you. The computing power is in this way distributed and aggregated, and you become a vital part of this equation.
