The present study focuses on the design, fabrication, and performance evaluation of a radiator which can be used in Eicher Trucks using aluminum as an alternative material providing a cost-effective solution. This study enhances the economic efficiency by using aluminum as the low-cost material without compromising the thermal efficiency while the standard dimension is maintained as 18.5 inches x 18.5 inches. Under varying conditions, theoretical heat transfer calculations were conducted, and radiator performances were predicted where convection and NTU-effectiveness methods were used. Despite manufacturing constraints, the custom radiator was constructed with 1-inch tubes, rectangular fins, and aluminum tanks. However, experimental tests, including hydraulic and flow assessments, revealed material limitations, particularly in the aluminum tanks, where leakage occurred under comparatively higher pressure. It was evident that aluminum provides cost benefits, but it may impact durability under operational stress. These findings contribute to the optimization of radiator design in automotive applications and will provide guidance while manufacturing.

Hexapod robots are increasingly used in hazardous environments where human intervention is risky. This study presents the design of a hexapod robot with a high-speed dynamic tripod gait, which ensures stability by keeping three legs grounded while the other three move forward. A detailed gait analysis was conducted, showing that the tripod gait enables efficient load distribution and continuous movement, even in challenging terrains. The foot-end trajectories for each leg were analyzed to optimize both translational and rotational motions. Torque calculations confirm the robot’s ability to carry its weight and perform smooth movement. The hexapod achieves a velocity range of 12–22 cm/s, with a battery runtime of 25.9 minutes and a body-supporting motor torque of 2.3 kg-cm. The results demonstrate that hexapod robots are well-suited for complex and risky environments through effective gait control and leg coordination.
