After choosing to go down the 3d printing route we looked into various design platforms like (Makerbot Thingiverse)
this platform allows users to access a database of components and if the components don’t already exist the components can be made and be uploaded to this site. this will also add another dimension to the robot making process. So we propose to our NGO to use this platform in order to get a much cheapr price rather than importing the parts of the robots from other countries. There are always forums on these platforms which means communication is available with other people to get help and crack any ideas.
This platform also has a customise section when you can customise existing components to your product specification. There are also simple design softwares like sketch up where you can easily create a simple component.
