COREMO TRAILER - Community Repair Mobile

Auteur avatarTimm Wille | Dernière modification 15/05/2024 par Crina

First Prototype of a Community Repair Mobile (COREMO) Trailer designed to provide repair services by means of #ASKotec (Access to Skills and Knowledge - open tech emergency case) and other tool-kits/ mobile makerspaces in remote areas with difficult road access. This prototype is currently developed in Kenya)

Introduction

Repair services of all kinds provided in workshops or other fixed locations are seldom available in remote rural areas of Kenya - as well as many other remote rural areas of the Global South. People, who are in real need of fixing their limited equipment or finding a solution to a technical problem, are stuck for lack of basic tools and materials.

This is why mobile repair services are not only a great solution, but also one that significantly reduces costs and the use of resources, while allowing people to be active and creative in the repair process.

This step-by-step tutorial serves as an Open Source set of instructions for the prototype of a Community Repair Mobile - COREMO (Trailer Edition) intended for remote areas.

COREMO Trailer will provide remote communities with access to repair services through the use of the #ASKotec (Access to Skills and Knowledge - open tech emergency case) and other mobile makerspaces/tool-kits.

COREMO is currently developed in Kenya by Adam Abdumalik with support from international makerspace community members.


COREMO Trailer serves as a first stage solution for future additional variations, modules and adaptations that will include: - Use of Solar Power (Soldering, Charging, etc.) through the addition of solar panels

- Solar electric mobility

- Scaling production, decentralized and Open Source implementation
