To answer to the widespread use of computers and internet, our project (Laborem) is to implement new tools for teachers and learners as remote laboratories, the objective is to increase the student motivation. A robotic arm, a modular motherboard and generic plugs are used by students to build their circuits. The learning objectives are to implement basic electronic circuit and to practice instruments use for test and measurement. Our objective is to offer an open source and low-cost e-lab to unite a community of remote laboratories. Accordingly, we have developed a software running on single-board computer like a Raspberry Pi with a solution based on a HTML web interface for the front-end and Python code for the back-end. It is now possible to run an automatic installation script and to switch between different acquisition equipment (oscilloscope, arbitrary function generator). For the hardware part, we have designed and realized a motherboard to access to 16 different electronic circuit which can be modified. Switches are implemented to activate and to deactivate components, also digital devices are inserted in the plugs like potentiometer controlled by I2C protocol. Finally, all the elements are integrated in a plastic box realized with a 3D printer. Future works are focused on increasing communication protocols (web services or BACnet/IP) and connecting various engineering education centers.
