PRD: Approved

Product is clearly described, with various intermediate goals to reach.
Goals (at least first ones) appear attainable: a 2d positioning mechanism holding a pen for plotting.

Design: Approved with amendments

Design is reasonably clear with regards to electronics
- [ ] additional parts may be necessary (servo drivers?), please update design as you find out
Mechanics:
- [ ] Please add a sketch showing your current idea of how 2d-movement will be achieved (positioning of motors and gear racks? lead screw?)
- [ ] Are there any expectations on how to avoid jamming if only one side of the arm is motorized?
- [ ] Is there a need for pen control (lowering / raising)?
