Overview:
The Sidekick is a desktop liquid dispensing robot, compatible with standard SBS microplates designed for accessible laboratory automation. It features an armature-based motion system and a fully 3D printed chassis to reduce overall mechanical complexity and accommodate user modification. Liquid dispensing is achieved with four solenoid driven positive displacement pumps that deliver 10 microliter increments. Control is provided over a USB serial interface using a simple vocabulary of commands, implemented in the form of a short Micro Python program. At a total price of $650, the Sidekick offers laboratories an easy to build, easily maintained, open-source liquid handling system for both research and pedagogical introductions to lab automation.
For a more in depth look on the systems and assembly, take a look at the paper in preparation. We’re planning to submit to Hardware X, and are just waiting back to hear from our independent testers to ensure the robot can be easily assembled and replicated by other analytical chemistry labs.

2021.11.04_SideKick_HardwareX_Draft3_againOperation:
While the Sidekick is still undergoing some final testing, it is fully functional! Here’s a demo of it plating an American Flag.
Documentation:
The Sidekick is fully open source, all of the assets (STL files, source code, PCB designs, assembly guide) can be found on the project’s GitHub page.
There is also a detailed set of build instructions so you can print your own! Please note, the Sidekick is currently undergoing independent testing, and some minor revisions will still be made as we continue to iron out kinks.
