NCR Canada Corporation is computer hardware and electronics manufacturing company that provides products and services that enable businesses to connect, interact and transact with their customers [1]. NCR is known in particular for its automated teller machines (ATM), Figure 1. NCR Canada recently set out to design a new ATM, with improved performance over its previous models. The project focused primarily on enhancing the tiltenator device, which tilts up and down to mate with two different guide sections through which documents travel. The overall ATM design project involves a broad range of tasks; however, Mike Johnston’s particular assignment was to design a new drivetrain system that would improve the performance of most components of the new ATM, but would have particular impact on the tilting guide device (tiltenator). This device tilts up and down to mate with two different guide sections through which documents travel.
Mike Johnston, a co-op student from the University of Waterloo, was asked by NCR to design a new, faster ATM drivetrain for increased document throughput and to identify an effective method to precisely control the tiltenator's position across a relatively large range of motion (20°).

The teaching objective for this case study is the synthesis and analysis of mechanisms for gears and power transmission system design. The case study includes need analysis, preliminary design (components selection), detail design analysis, and implementation. The case study also provides a detailed analysis and comparisons of key factors for belt selection and Planetary Gear Analysis.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg, and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
