Suspension and steering are subsystems to any automobile which determine how the vehicle dynamically behaves with driver's and terrain's combines input and output as response of the vehicle deciding direction, stability and ride, roll characteristics which were used in this study to obtain optimum lap times. The roll cage acts as a skeleton to the body and the suspension system as the limbs trying to maintain stability and safety in the cockpit. This study is based on BAJA SAE rulebook constraints. An iterative process is adopted to finalize suspension parameters followed by ride and roll calculations and suspension geometry selection. The entire setup is simulated using lotus shark suspension analysis and MSC Adams car multibody dynamics suspension testing in various simulations and loading conditions. The change in suspension parameters such as camber gain, castor, wheelbase and toe change during different conditions were noted as design decision parameters and the geometry was optimized accordingly. The subsystem component design such as control arms and mountings were designed using CAD and simulated using FEA modelling on ANSYS simulation software. The resulting structural deformation and dynamic stability were chosen as design decision parameters. The manufacturing process was aided by use of jigs and fixtures to eliminate errors.

“…This double half-h-bridge motor driver allows the control of the motor using PWM signals from a microcontroller. The said driver was chosen for its high current and voltage limits 24) . The motors chosen are capable of drawing about 6 amperes of current at full load at 12 volts; most of the widely available drivers such as L298 drivers are only capable of handling 3 amperes of current at most.…”

The robotic platforms currently available for testing the software stability and functionality are expensive and are not highly customizable in terms of hardware. This makes the platforms out of reach of the grasp of researchers and small-scale start-ups. We have proposed a design of a robotic platform that is easier to manufacture and cheaper to build (totaling under USD 1000). The components used are easily available and are cheaper as compared to the components of currently available robotic solutions. The design features of the platform are explored along with factors and features that make the proposed platform favorable to small-scale researchers and startups. The components of the platform are discussed along with their purpose in the design. A model that is highly customizable, easy and cheap to manufacture, and capable of carrying out general tasks of navigation and manipulation was made. Scaling the model physically down to making its smallest gearbox (in wrist actuator) of about 10 cm in diameter, was also made possible using the design principles proposed in the paper. Further scope of improvement and ideas for the next version design were also explored.

“…In addition, activated carbon (AC) is a type of carbonaceous material that has undergone treatment. It possesses a consistent surface shape, notable biocompatibility, favorable mechanical strength, and stability [2,11]. According the preceding investigation conducted by Kaggwa et al, [12], it was observed that the incorporation of activated carbon in nanofluid resulted in a notable augmentation of lubricant viscosity and enhancement of heat transfer efficiency.…”

The common use of petroleum-based metalworking fluids (MWFs) in industry harms the environment and human beings. The biggest disadvantage of RBD palm oil is its low thermal-oxidative stability. As a result, the goal of this research is to create an innovation for palm oil based MWFs. The new creation of modified palm oils (MPOs) has been produced by a transesterification process with palm methyl ester to trimethylolpropane molar ratios of 3.5:1. Later, at a concentration of 0.025wt.%, the MPOs were mixed with single and hybrid additives such as activated carbon (AC) (MPOa), tungsten disulphide (WS2) (MPOw) and hybrid AC with WS2 (MPOaw). The physicochemical parameters of MPOs were studied, including viscosity, and acid value. The physicochemical properties were evaluated as per ASTM standards over a period of 4 weeks to check the state of lubricant and observable changes in the properties during this period According to the findings, MPOaw shows enhanced thermal (high viscosity index 365-387) and oxidative stability (lubricant storage). Moreover, MPOaw recorded has higher antioxidant properties that can help prevent or slow down the oxidation process, reducing the production of acids and subsequently lowering the acid value (0.14 -0.19 mg NaOH/g). In conclusion, it has been proven that MPOaw has the best performance and the potential to have a positive effect on the industry as a sustainable MWF for machining processes.
