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 study discusses the three essential process parameters cutting speed, feed and depth of cut on the quality of the tool during turning operation. A high-strength stainless steel tool coated with tungsten carbide is used. The tool is further strengthened using cryogenic treatment by immersing it in liquid nitrogen for 24 h and 36 h respectively. The surface roughness of the simple coated tool and the processed tool is compared using optimization techniques like the Taguchi technique and ANOVA. The analysis revealed that the surface roughness of the simple coated tool insert was 0.5 μm, whereas the surface roughness of the tool inserts immersed in liquid nitrogen for 36 h was 12.5 μm. The processed tool insert became brittle which lead to an increase in surface roughness after the turning operation. Three different algorithms like Grass Hopper Optimization, Moth Flame Optimization, and Salp Swarm Optimization were used to observe the feasibility of the optimization techniques. The Moth Flame Optimization algorithm had good convergence and also delivered results that were correlating with the ANOVA. It is concluded that while keeping a high tool rotation speed of 984.46 rpm, a low feed of 91.4 mm/min and a depth of cut of 0.25 mm resulted in a low surface roughness of simple coated tool insert was 0.59 μm.

“…There hasn't been a robot model which is highly customizable in terms of hardware. In this paper, we are proposing a design of a robotic platform that is capable of general manipulation and navigation tasks, along with options for customization and design changes for specific experimentations or applications 9,10) . The proposed model is highly customizable in the sense that the user can control or change the physical size of the model according to the needs, which has not been seen in many available robotic models.…”

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.
