A CMOS video sensor for High Dynamic Range (HDR) imaging is discussed. Unlike traditional memoryintensive methods for HDR imaging where frames with different exposure times are digitally combined to obtain an HDR frame, HDR imaging is accomplished in the sensor at pixel level by digitally combining sub-pixels with different exposure times to obtain an HDR pixel. In HDR mode, the prototype video sensor demonstrated a phenomenal 26dB improvement in dynamic range over normal mode.
The e-Yantra project at IIT Bombay conducts an online competition, e-Yantra Robotics Competition (eYRC) which uses a Project Based Learning (PBL) methodology to train students to implement a robotics project in a step-by-step manner over a five month period. Participation is absolutely free. The competition provides all resources -robot, accessories, and a problem statement -to a participating team. If selected for the finals, e-Yantra pays for them to come to the finals at IIT Bombay. This makes the competition accessible to resource-poor student teams. In this paper we describe the methodology used in the 6th edition of eYRC, eYRC-2017 where we experimented with a Theme (projects abstracted into rulebooks) involving an advanced topic -3D Designing and interfacing with sensors and actuators. We demonstrate that the learning outcomes are consistent with our previous studies [1]. We infer that even 3D designing to create a working model can be effectively learnt in a competition mode through PBL.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
