Translation System Assembly
This design was made according to research and modeling found in the above documents. The bottom component contains the motor attached to a driving roller and a plain bearing on a steel shoulder shaft. The catheter is fed through the small hole seen in the center right of the image. The motor is given a small step size to provide incremental pushes to the catheter and the urethane rollers provide enough friction to guide any catheter. The top section can be seen guided by the four vertical shafts placed into the bottom component. The top section contains two more urethane rollers alligned with those on the bottom and is weighted to add more friction to the system.
Rotation System Assembly
The rotation model was made in a similar way to the translation system. However, to induce rotation, the catheter is feed axially to the bearings. This allows for a twisting motion to be applied onto the catherter over the pushing force caused by the translation system. Like the translation, the bottom section contains space for a motor and driver wheel. The catheter is held in place as it rotates by the small hole in the back of the model. The top componenet supports a single bearing and provides a downward push on the catheter to help restrain it as it rotates.
