Objective: Lift meant to carry food from the rooftop restaurant and kitchen to the indoor restaurant on the lower floor.  

Approach: This is the first locally built dumbwaiter lift in Bangladesh.  I designed the mechanism of the lift using a motor driver, two high torque motors that were attached to an Arduino board. The motor driver was custom-made, using relays and optocouplers.  The woodworking and designing were done by Studio Bangi (a renowned architecture company in Bangladesh).
