Club projects

Bee-Bots 3.0: Beebots is a swarm robotics project that aims to explore swarm intelligence and coordination using biologically-inspired algorithms. It explores the fascinating idea of simple local behaviors giving rise to global action. Project BeeBots is currently working on shape formation and shape recovery behavior in a swarm after obstacle interaction.

DarkSight: Imaging in low light is challenging due to very low photon count and low SNR (signal to noise ratio). Our network operates directly on raw sensory data from cameras and aided by thermally imaged shots of a low-lit environment and maps to high exposure shots of the corresponding environment producing promising results.

OTA Programming Module: The project aims to give AVR Microcontrollers the ability to receive and update their applications wirelessly. It makes use of a NodeMCU to connect to the WiFi which then serially communicates any updates it receives to the AVR Microcontroller.

Video Denoising without Flow Estimation: Image denoising approach for video denoising leads is highly time consuming and expensive, rendering these algorithms unusable on Embedded Devices and Real-Time applications. Denoising results of our network feature remarkable temporal coherence, very low flickering, and excellent detail preservation without a flow estimation step. Project is completed and is to be converted to a research paper and aimed to be published at international conferences.

UAV-UGV: A cooperative parcel delivery system for an unmanned aerial vehicle (UAV) and an unmanned ground vehicle (UGV). The UAV enhances the poor traversability of the UGV by providing a wider range of scanning and mapping from the air and also responsible for last mile delivery of parcels. Whereas UGV carries the parcels all way long and provides the charging support for UAV.

UHUGV: An amphibious bot that is capable of traversing both land and underwater. The ground locomotion is achieved by track drive and the underwater motion is achieved by bio-mimicking fin ray fish locomotion. The robot has a track drive mechanism for the purpose of traveling in marshy terrains.

RISC V Processor Core: RISC-V, is an open standard instruction set architecture provided under open source licenses that do not require fees to use. This is spider R&D's First attempt at designing a novel microprocessor core that implements the I(Integer), M(Multiply) and F(Floating point) extensions of the RISC-V instruction Set. FPGA implementation of a basic RISC-V IMF processor core is complete.

Standard Cell Characterization Tool: This project attempts to build an open source tool to characterize standard cells (Both custom made and foundry issued cells). The open source tool once developed can be widely used to characterize the timing ,power characteristics and generate liberty files which can be used along with the normal design flow for placement and STA.

Induction Process

Timeline: Mid-May to August 1st week

Spider Inductions are conducted through the Inductions Portal developed by Spider Member Themselves - https://inductions.spider.nitt.edu/

Spider opens inductions for B.Tech first years for all the four profiles - Algorithms, App Dev, Tronix and Web Dev.

The Tronix Profile has 3 sub-domains - Embedded and Electronics (EE), Signal Processing and Machine Learning (SPML), Robotics and Control.


  • We release 3(minimum) tasks for each profile, with a gradually increasing level of difficulty. App Dev and Web Dev domains may also ask you to take up a small summer project after the applicant successfully completes the tasks.
  • Scores will be awarded for each of the task submissions, and depending on their performance in the tasks, applicants are shortlisted for the Personal Interview Round.
  • The personal interview round checks the applicants’ understanding of the technical concepts they have learned so far in the induction process. And also checks their attitude and passion towards learning and ideating on new things

We provide the necessary learning resources (https://spider.nitt.edu/getting-started/) for each of the domains to get you started on the pursuit of your interests. All first year students are free to apply to one or more profiles depending on their interests. We recommend not applying to more than 2 domains as it would get difficult to manage your time for completing the tasks. For each profile we assign mentors to each of the applicants to guide them throughout the induction process, for any kind of help they might need with respect to the tasks or finding the right resources. Lastly, it doesn’t matter if you are just a beginner or just beginning to learn in these fields before the start of the induction process. What matters is how well you make use of the resources we provide you to learn and adapt to these new things quickly. A keen interest and passion for learning new technologies is what is really needed to be a part of Spider R&D
