Project Information
A quick search online for pen plotters will show many different types available, but all of them are built within a fixed frame. The Self-Propelled Pen Plotter attempts a "frameless" iteration of the pen plotter, where the pen is driven by two wheels instead of moving along fixed rails.
The plotter is driven by two stepper motors for positioning and a servo motor to lift and lower the pen. An image can be stored in the plotters memory to allow for operation without connection to a host computer.
Unconstrained by a fixed size frame, a clear application for this project is in producing custom signage which requires large, simple images produced in relatively small batches. Lacking a frame also makes the plotter portable, allowing for on-site plotting of said signage.
In short, this project aims to produce a pen plotter which does without the conventional fixed frame to allow for operation in a greater number of environments.

Recently, the living standard is getting higher leading to the fact that people need to buy more and more products. Especially when the Covid pandemic has happened, the online order services have grown significantly. This is the reason why a growing number of warehouses have been built on over the world, which increases the need for heavy labour jobs for loading and unloading goods. To assist humans, the project Autonomous Robot Arm with the Inventory System is developed in order to replace people doing heavy and repeating tasks at the warehouses. With the vision sensor, the Robot is able to detect certain positions to grab the packages, place them in the appropriate storage base on their colours and automatically update the information to the inventory website.
Project Information
The project consists of a height-adjustable grow LED platform, Air Pump, automated Temperature, pH, and Total-Dissolved Solids (TDS) measurement sensors. All data is displayed on a touchscreen LCD panel. The main system powering the electronic backend is the Raspberry Pi 3B+ Model. It is connected to an Arduino Uno which is used for measuring the analog signals from the pH and TDS meters. The Raspberry Pi also drives a motor relay to control the DC Linear Actuators used to raise/lower the grow lights. Finally the Raspberry Pi also controls an electromechanical relay which provides control over the Air Pump and grow LEDs. The LCD panel displays the pH, Temperature, and TDS values over a 24-hour period, and allows for Automatic / Manual sample collection. The maximum height of the plants growable is up to 3 feet - so it is suitable for larger crops such as Tomatoes, Corn, etc.
Project Information
We constructed a portable electrocardiogram (ECG) monitor that offers basic, reliable cardiac waveform data collection over short or hours-long monitoring when worn by a patient and that can be used in either hospitals or casual environments. It offers convenient usage by healthcare providers, generally nurses or clinical staff, who need direct and low-maintenance ECG waveform collection even at peak-occupancy when stationary or high-end patient monitors are unavailable. It is simple enough for a patient to leave the clinical site, return to regular life, and return the device for data uploading in the manner of a Holter monitor. The interface is 'no-frills' and maximally simple, with two buttons and a patient ID# plus date/time selector. Internally, the CardioPort receives analog skin voltages from external electrodes (two currently but this can scale up for waveform verisimilitude), converts it to digital data, passes this to the Arduino Pro Mini for display to an LCD screen and storage to a Micro SD card. This card can be read on a computer by a Small Basic applet resembling a paper ECG printout. The real-time clock accurately matches voltage to time to generate the ECG trace and help caregivers diagnose arrhythmias, bradycardia, tachycardia and other irregularities.
Project Information
High-flow nasal cannula is an oxygen therapy (HFNC), which consists of an air/oxygen mixer, an active humidifier, a heated tube and a nasal cannula, can deliver heated and humidified medical gas in a flow. Our goal is to provide a consistent source of humidification to the respiratory circuit to mimic this process. By creating this humidifier our objective is to provide a precise water vapour throughout the nasal cannula circuit, this is important as too much water vapour can lead to bacterial growth. The overall goal of this device is to eliminate dry nose and throat and nasal pain to promote the tolerance of oxygen therapy via the improvement of oxygen quality.
Project Information
The device collects sensor’s data and compares the data with the condition in real time continuously. If the sensor’s data signals exceed/ or violate those conditions, or it detects any faulty situation then the device will immediately alert the user via phone application notification or email, depending on application settings. This Project Mainly consists two Parts, which are as follows:
- Calibrated 10V,20 V and 20 ma Signal Generator. Here we are generating 20 ma constant Current Irrespective of Load and Temperature variation. These Voltage and current signal power Up all the sensors connected To the Main IOT Hardware.
- Main IOT hardware. All the field Sensors are connected to the Main IOT hardware which continuously Monitoring sensor’s data and gives alert On Fault condition.
