Tried to lift pneumatic unit using the latest clamping mechanism we designed (success!) Arduino coding to configure relay system Having completed the custom 3d-printed and built clamping mechanism for the pneumatic unit, we proceeded to test the clamping ability by manually lifting the unit using the clamping system. Below are…

Our relay controller box (with remote control) just arrived! Here is an overview of the components. The relay comes with a set of numbered wires, each helping to relay the signal when a specific button on the remote control is pressed.                  …

We designed a simple battery monitor (using Arduino’s internal voltage sensor + LED light + some coding) for the system such that when the battery’s voltage (normally about 12-12.5V) falls below 11.5V, the LED will light up with an orange color to indicate to the technicians that the battery is…

We have finally gotten around to modifying that particular Bell Crank design. Now, our arm is able to go down all the way to right above the base of the trolley (where the pneumatic units will be parked) and is able to go up to the height of 3m. Hurrah!!!…

We decided to add the wheels into the trolley. This video shows how we prepared the wheels. wheel setup We also had to cut the protruding screws that hold the wheel to the base as these screws were blocking the wheels’ proper rotation. wheel cut Lastly, this video shows the…

Yesterday, we added actuators B and C, as well as an optimised intermediary aluminium profile to solve the problem of the secondary arm not being able to rotate sufficiently downwards to pick up/release the pneumatic unit. We thought that we should maximise the rotation of the intermediary aluminium profile to…

At the start of today, this was the configuration of the actuators (2 x Actuators A in the parallel configuration below) and actuator B on top.                         As we were going for the double-actuator system, we proceeded to add…
