“…Our rationale for creating such a robot is to increase the transparency of the manufacturing process of the robot, helping users build a better understanding of the system; add more customizability so that users can adapt the robot to their individual use-case; and have this robot serve as an introduction to multiple fields such as programming, manufacturing, life sciences, and chemistry. Our goals were (1) to design an LHR that can easily be assembled with snaptogether laser-cut parts, which are easily modified from open-source blueprints (i.e., CAD files) and is compatible with standard lab plasticware (e.g., 96-well plates); (2) to use inexpensive open-source DIY electronics such as Arduino boards [18,19]; (3) to enable distributed manufacturing (i.e., each individual user can manufacture the parts locally for themselves) [20], (4) to integrate this robot fully with a block-based programming language to enable nonspecialist users to operate and automate protocols; (5) to characterize the performance parameters of this robot, and (6) to take into account the perspective of potential future users (i.e., teachers) through a joint and iterative co-design process. We first describe the design of the A) The main frame of the robot is made of laser-cut plastic parts, while all consumables (i.e.…”
