I spent the majority of the week working on the scissor lift. I was able to build a prototype that worked. As we wanted the actual height to be a bit higher, I reviewed the design to accommodate this. I also looked at other potential design choices to improve the stability, such as changing out the lift platform and changing the number of scissor components used. The lift needs to be able to be controlled, so we chose to use a linear stepper motor to do this. Next week I hope to build out the final scissor lift and implement a reasonable system to incorporate the linear stepper motor. I do feel as though I’m on schedule.
