Before we can code anything to control the actuators in our lifting system, we first need to derive an algorithm for the process. As of now, we are not sure which actuator will take longer to fully extend as we have not completed our real-life motion study, so two key…

Today, we plan to build a base for our lifting arm. But first, we will discover the CG of our arm. We require the CG of arm to ensure that the far edge of the base (pivot) is beyond the CG of arm such that our lifting arm will not…

                          After multiple redesigns and dimensions adjustments, we have finally achieved a design that can seamlessly pick up loads on the trolley base and lift the to a height of 2.9m for installation purposes, in the working space…

We considered some preliminary designs which use actuators (pictured below). However, after doing some motion studies on our scaled paper model and some height calculations, we concluded that they were not the most suitable for our purposes of lifting a pneumatic unit from the ground and installing it at a…

Based on the requirements and space restrictions presented by LTA and SMRT during the first depot visit, we went through a few iterations of possible crane design (as will be detailed in another post – insert hyperlink). As of 3 Jun, we sketched out our best conceived design on paper,…
