Neera is Rubiks Cube solver robot, designed and built using LEGO Mindstorms NXT and programmed using NXC language.

Hardware is comprised of three major parts.

1. Arm with a motor to flip the cube.
2. Arm with a motor to scan the cube.
3. A motor that rotates the cube.

The aim of this project was to build a low cost prototype Quad-rotor and come up with system stabilization algorithm for the stabilizing the quad rotor. We came up with a mathematical model of a quad-rotor to correct pitch and roll errors by changing motor thrust and on getting meaningful data from inertial measurement unit by filtering noisy sensor data using complementary filters.

Based on this work, presented a paper entitled ‘Design of Quadcopter with closed loop control system’ at Visvesvaraya Technological University, Belgaum, in 2011.

Report Presentation

Project Vyoma is a research project at RVCE to design Unmanned Aerial Vehicles (UAVs).

We worked on data logging system which captured data during flight from various sensors like GPS, pressure sensor and inertial measurement unit into a SD card to be retrieved later for analysis by aerodynamics team.

This data helped us improve the flight performance from 18th position (2010) to 8th position (2011) among 70 teams from all over the world in the SAE Aero Design event at Atlanta.
