Trying is the only way to find out

Tipsy the multimodal Search and rescue robot

Tipsy is a multimodal surveillance drone capable of flying and driving. Tipsy was inspired by drones used for disaster response that must traverse precarious and variable environments. Tipsy can surmount obstacles by flying over them as well as use its propellers to balance while driving. It is also more energy efficient as driving is more efficient than sustained flight. Tipsy is very cost-effective as it is built using standard RC-car and FPV drone components making it more accessible to the communities that need it most. Videos, CAD models, and a report on the design are available in the article.

Rickishi the Sumo wresting robot

Risckishi is a sumo wrestling robot designed to push its opponents out of a rubber ring. Rickishi was designed to have better pushing power and more stability and its opponents while also having a wedge to lift its opponents. All the electrical and mechanical hardware was fabricated in-house including the chassis, PCB and silicone wheels. A full report and CAD model is available in the article.

Vibration testing model

This rig was designed to test trailing arm suspensions of different geometries. A stepper motor attached to a scotch yoke mechanism generates a forced vibration at the base of the trailing arm. The linear rails constrain the motion of the two bodies vertically to simulate a quarter-car model. The forced-vibration frequency, amplitude, trailing arm length, suspension spring rate, the top mass and pivot points can all be varied by adjusting elements of the rig.

16s2p LIFEPO4 battery

This high-power battery uses Headway 38120 batteries in the 16S2P configuration to deliver 400A of current at 51.2V to the Hyperloop vehicle. The low-voltage contraint due to safety regulations meant that very high current was necessary to meet the power requirements of the vehicle. As a result, the bussbars, housing and BMS had to be carefully designed to ensure safe operation.

FEA thermal analysis of a turducken

How long does it take to cook a turkey, stuffed with a duck, stuffed with a chicken, stuffed with potato filling? I did an FEA thermal analysis using ANYS workbench to find out. The thermal properties of the different foods were calculated by considering the proportions and thermal properties of its constituents, ie. protein, carbohydrates, ash (burnt food). These properties were placed on a mesh of a turkey generated using Altair Hypermesh and it was placed in a virtual oven to bake.

FEA stress analysis of a Wind turbine

Simulated the stress exerted on a wind turbine during wind load, a 500kg nacelle, high and low temperatures, and with one of the blades missing (extreme stress case). Performed fatigue, buckling and mechanical stress analysis .
