About Us

We are group of Nerds who are doing research for fun to develop something useful to bring comfort in our lives by developing MEMS based sensors and solutions of a size of the diameter hair. MEMS are very small scale devices that are of the size of micro meter (1 million times smaller than a meter). These magical and nonvisible MEMS devices are everywhere around you from airplane, car to a mobile phone.

    Development of an ultra-low-g highly sensitive gravimeter in the applications of MEMS gravimetry and seismology e.g., mineral exploration, measurement of earth’s density variation, earthquake detection and observation, geophysical sensing, etc. The development of such a gravimeter will result in greater accuracy in the measurement of gravity and mineral exploration. This requires readily available, low cost, highly precise, and low cost inertial sensors. Among these inertial sensors, the advancements in the design and production of low frequency MEMS accelerometers is indispensable for earthquake monitoring and seismic surveying. Geometric Anti-spring (GAS) technology has been used for lowering the spring constants of accelerometers in macro scale for a while now. A similar principle can be used for MEMS gravimeters, for which the GAS typically consists of a set of curved, pre-stressed springs attached to the proof mass. The springs can be compressed or loaded passively with a force due to earth gravity, or actively with a dedicated actuation system. The compression of the springs effectively decreases the resonance frequency along the axis of the sensitivity of the mass-spring system, which significantly increases the sensitivity of the gravimeter. The negative stiffness property of other springs as curved beams has also been utilized in literature for the purpose of lowering the spring constant hand hence reducing the resonant frequency of the device

IMU based Gesture Controlled Mobile Robot:
We have implemented a system level applicationthrough which the user can give commands to wireless robots using gestures based on motion capture sensors mounted on human hand and joints. Through this method the user can control or navigate the robot by using the gestures of the hand, thereby interacting with the robotic system. The command signals are tracked using the motion sensors. The gestures provide a rich and intuitive form of interaction for controlling robots. Application area are Medical Surgery, Surveillance Robots, Motion Capture Tools

Implementation of Inertial navigation system for Autonomous Path Planning of Mobile Robot: We have implemented a system level application though which a robot can navigate autonomously from a stating point to an end point, the on-board integrated controller creates the necessary trajectories that will drive the robot. The on-board Inertial sensors measure the motion parameters of the robot and the controller estimates the position, velocity, heading and orientation of the robot. The on-board controller also implements steering correction in case of deviation from its reference heading. Application areas are Autonomous Robots, Autonomous Cars, Surveillance Robots, Guidance Systems, Navigation Systems.
