In Phase 1 (Design), we stumbled a lot as we were confused about which specific hardware we should use. When we only considered the linear actuator initially, we had to think about the force required to push the syringes, how to convert the distance pushed by the actuator into the volume of paint dispensed, and many other considerations. However, we initially did not know that there exist peristaltic pumps that would not require us to consider all the abovementioned factors. If we had researched more on what kind of motors and pumps existed, we could have avoided the many rounds of designing.
