Brief Summary:
This is a single centre, non-randomized, tandem colonoscopy trial of the NISInspire-C System, followed immediately by a conventional colonoscope (CC). Each trial subject will undergo colonoscopy using the NISInspire-C system, followed immediately by CC. The purpose of this study is to obtain observational data on the safety profile, feasibility and usability of the NISInspire-C System in performing diagnostic colonoscopy in human subjects. The level of procedural pain experienced by subjects will also be explored.

Subjects receiving tandem colonoscopies using the NISInspire-C System followed by a Conventional Colonoscopy
Device: NISInspire-C System
The NISInspire-C System is a disposable robotic colonoscopy system that consists of a flexible slender insertion tube designed to ensure non-invasive, reliable and safe colorectal screening. It comprises of two components: NISInspire-C Console, and the NISInspire-C Disposable Colonoscope.

Primary Outcome Measures :
  1. Safety: Incidence of Intra-Operative and Post-Operative Adverse Events [ Time Frame: 10 Days ]
    Number of Adverse Events

  2. Feasibility: Caecal Intubation Rate (CIR) [ Time Frame: 1 Hour ]
    CIR: Number of Times Caecum is Reached

  3. Feasibility: Time-to-Caecum (TTC) [ Time Frame: 1 Hour ]
    TTC: Time to Reach Caecum

  4. Feasibility: Polyp Detection Rate (PDR) [ Time Frame: 1 Hour ]
    PDR: Number of Polyps Detected

Secondary Outcome Measures :
  1. Usability [ Time Frame: Day 1 (Day of Procedure) ]
    Feedback on General Usage of the NISInspire-C Disposable Colonoscope

Other Outcome Measures:
  1. Intra-Procedural Pain (Exploratory Outcome) [ Time Frame: Day 1 (Day of Procedure) ]
    The Level of Procedural Pain Experienced by Subjects Undergoing the Colonoscopy Procedures will be Explored.
