Autonomous vehicle for warehouse management
-
Development of an Autonomous Mobile Robot which works with natural navigation for warehouse management.
AMR uses 2-D LiDAR, 3-D camera, Encoders, IMU, sonars etc for the navigation.
Focusing on localization and navigation .The development is being done with the ROS framework. -
3-D Vision based bin picking robot
-
In this project, items kept in a bin will be picked up using the ABB IRB1200 robot, by making use of the data from the 3-D camera(ZED). The picking positions for each item in the basket were obtained from the PointCloud data and were to be sent to the master PC. It's from this PC only,the commands for controlling the robot were sent to the IRC5 controller. The entire process was developed in the ROS framework

Localization is done for the workspace using the nodes with RFID tags and black strips of lines were used for assisting the navigation across the arena.The robot basically consists of two controllers:ie primary controller with a NodeMCU and a secondary controller with an Arduino Mega for motion control .Primary controller deals with the commands sending and receival with the CPS(Central Processing System) and secondary controller.In other terms it could be defined as the brain of the system.Secondary controller deals with the basic motion across the grids.It consists of LSA 08 advanced line sensor and the MPU 6050 IMU which asssists its motion through the environment
Communication between primary and secondary controllers happens through serial communication
Communication between primary controller and the CPS (Central Processing System) happens across MQTTOther creators -

An offensive smelling toilet is more often caused by a lack of cleaning.While regular cleaning definitely minimizes toilet odor,depending on the usage rate,the frequency in which toilet should be cleaned would varies.

An offensive smelling toilet is more often caused by a lack of cleaning.While regular cleaning definitely minimizes toilet odor,depending on the usage rate,the frequency in which toilet should be cleaned would varies. In this project a solution is proposed to analyze and detect various odour levels in rest rooms/toilets.It produces alerts at instances where the odor level exceeds the limit.The system consists of a transmitter module which is kept inside the toilet and a receiver/display module which is kept either just outside toilet or within the vicinity of cleaning staffs.
The sytem consists of various gas sensors like MQ2,MQ3,MQ6,MQ135 for detecting different gaseous componenets in the environment. The sensor values were logged for few hours and k-means clustering was done for classifying the values into two different regions. Depending on the average distance of the new sensor values from the centroid values,the condition in the restroom would be analyzed. Based on the different odour level detected,the display color of LED indicator placed outside the toilet changes. The communication across the transmitter and receiver module happens across NRF module. Arduino Mega was used as the main controller for the transmitter and receiver modulesOther creators -

With constant increase of vehicle agglomeration worldwide,car parking is one of the major concerns in terms of space occupation in densely populated cities.cities.Though Multi Level Car Parking (MLCP) system provides a relief for this issue,looking for empty parking spaces and retrieving parked in congested parking spaces can be painstaking and time consuming.
As a cost effective solution, a four wheel driven MLCP assisting mobile robot was proposed.The robot will be moving across the entire parking area monitoring the vehicles parked in the MLCP and corresponding parking slot.Sensor fusion techniques were implemented minimizing the human intervention in the robot motion.Camera mounted on top of the mobile robot collects the images of registration number plates of the vehicles parked in the MLCP.The entire set of information collected will be updated into the cloud data base.Image processing techniques were used for extracting information from these images.Operation of the robot as well as the camera can be controlled using an android tablet. Information collected can be used for monitoringwhether vehicles are parked in allocated slot itself.Other creators -

A gesture controlled mobile robot on AVR platform ,which assists the rescue aiding operators in post rescue aiding operations.The objective of this project is to build a mobile robot that can be controlled by hand gestures. User will be able to control motions of the robot by wearing the 0controller glove and performing predefined gestures. This project provides a basic platform for potential applications like human-machine interfacing. For this project we are using a gyro controlled transmitter glove for the direction and speed control of the robot. For efficient aiding in commando operating and in the field of post disaster operation we are employing gas detection,human detection and temperature sensing.
