Suraj Kumar, Aditya Rallapalli, Ashok Kumar Kakula +1
India achieved a significant milestone on August 2023, becoming the fourth country to accomplish a soft landing on the Moon. This paper presents the powered descen…
Learning based Modelling of Throttleable Engine Dynamics for Lunar Landing Mission
Suraj Kumar, Aditya Rallapalli, Bharat Kumar GVP
Typical lunar landing missions involve multiple phases of braking to achieve soft-landing. The propulsion system configuration for these missions consists of throttleable engines.…
Enhanced Algorithm for Mobile Robot Path Planning with Non-Holonomic Constraints
Suraj Kumar, Sudheendra R, Aditya R +2
In this paper, a novel method for path planning of mobile robots is proposed, taking into account the non-holonomic turn radius constraints and finite dimensions of the robot. The…
