Final Design:

Here is our final design! The details below are just some of the areas where our ingenuity shone through heehee

1. Bell crank: correct actuator and lifting arm placement
2. Double Parallel Actuators: Additional strength and sturdiness
3. Wire Housing: Housing for motor driver and Arduino Due
4. Motor Driver: Greater customizability of control system
5. Clamps: Custom-built and optimized to fit unit, not purchased from market
6. Fixed Connection: Additional strength and sturdiness
7. Reinforcements: Additional strength and sturdiness
8. Car Battery: Independent of external power source, greater mobility
9. Trolley: Transport unit from storage space to MRT
10. Aluminum Profile + Screws + Brackets: Faster, customisable

 

Progress:

Preliminary visits to SMRT:

pneumatic units.

Train on a raised platform for maintenance.

Space constraints to install the unit.

 

Initial Design:

initial design using a retractable arm and hook to pick up the unit.

 

Second site vist to SMRT:

Various updated dimensions and details. The design was modified to better meet these constraints.

 

 

Revised design with actuators:

Revised design with a double actuator system for increased strength and mobility.

 

Prototype:

Clamping system:

Use of many hand clamps to create a support system to lift the unit.
