3D Printed Ceramic Bricks

Introduction
Combining a traditional building material (ceramics) with a new fabrication technique (3D printing) to re-think an ancient building component (bricks), this project demonstrates how 3D printers can become portable, inexpensive brick factories for large-scale construction. Bricks are an ancient building component and their fabrication has seen several innovations throughout history; however it has consistently relied on a system of molds or extrusions that produce the same shape hundreds, or thousands, of times. This project is an exploration of a new fabrication tool for bricks: desktop 3D printers. This technique does not rely on molds, but rather prints each brick individually, allowing users to fabricate complex forms within which each brick can be unique.

This tube will be very useful to do work from a safe distance. We can use this tube for cutting, brushing, cleaning, monitoring, holding and for many other types of work. This tube will work as a Robotic arm.

Mechanism: According to the diagram there will be a flexible rubber tube which will be filled with ferrofluid. The front side of this tube will be closed and the back side will be attached with a coil (Electro Magnet) and a handle.

How will this tube work?
When electricity will work to convert coil into electromagnet then the ferrofluid, which is in liquid form will be converted into solid form and this flexible tube will become a hard tube and ...

Autonomous Robot for underwater exploration with high cruising speed and efficient in terms of propulsion and stability. Designed robot is mimics the biology of a fish for its behavioral function and its structural anatomies. Among the various biological locomotion techniques in liquid environment, the fish appears to have most characteristics in a single body. This model is developed for low radii of curvatures with high cruising speeds with an ability of autonomous obstacle avoidance. This model is an example for autonomous underwater vehicles having low coefficient of drag for the body which gives the advantage of less energy requirement for higher speeds.

The main challenges include hardware performance in terms of propulsion efficiency, mechanical robustness, maneuverability, adaptability and autonomy. The inherent problems ...

This study aimed to design and develop a multi-purpose controller to measure and control moisture, temperature, and time. Specifically, it aimed to design and develop microcontroller circuit for the controller; make assembly language program for the microcontroller; evaluate the readings of moisture and temperature of each unit by measuring the moisture content and temperature of a crop processing machine. The study provides easy-to-use processing machines for farmers and small-scale crop processing entrepreneurs.

The system used assembly language program. PICKIT 2 Compiler was used to make the assembly language source program. The system flowchart was used as the basis in developing the assembly program. In the system flowchart, the controller started by choosing the unit to be used. ...

The present automatic transmission is fully mechanically controlled and the cost is very high. In this study, a gear shifting mechanism was designed and applied on a clutch featured bike to make the gear transmission process faster and less destructible for the driver using push button system design. But the gear transmission mechanism designed makes driving easier and to achieve efficient driving. This new device must be reliable, has small dimensions, economical and low maintenance cost. This project aims to improve the gear shifting process with a suitable control mechanism to implement in clutch featured bikes. According to the suggested gear shifting method, the selects the transmission gear as per the speed of the vehicle without any human interference .A ...

The project has its bases in two existing technologies. The first one is a multirotor drone and the second is an articulated robot. Their combination results in a DROBOT. The main purpose of this project is to combine both flexibility characteristics to ensure feasibility of some tasks.

The environment defined to develop this product is the building process of steel structures. In this scenario, a group of DROBOTS is assigned to monitor the process and to perfume some tasks, like welding. Therefore, the context of this project is the development of this special DROBOT, specialized at welding tasks.

The basic concept of a DROBOT is that it features articulated joints at the middle of its mains ...

Our project is about agriculture & photography purposes. The idea is that we can use drones for spraying pesticides on crops. Spraying pesticides on crops is a very big problem because this pesticide is very harmful for the human body and it causes various diseases. A spraying machine is attached to the drone, so when it flies over crops it can easily spray a desired amount of pesticide. The only human effort on this idea during the spraying is that the drone is controlled by a human with the help of a remote control.

One more concept on which we are working, is that use of drone to extinguish fire where the firefighters can't reach ...

Working Principle: With a very low budget (around 100 US dollars) we were able to make a full functioning 4-axes pick and place robot. In present situation the dominance of pick and place robot in industries is much higher than other type of robots and they are very costly. Robot we made consist of servo motors(4 nos), Arduino Uno(1), and remote controller made up of push buttons(8+2),dead man switch, LED display which works upon 4-bar mechanism and we were able to give it 4 axes movement that is two rectilinear motion and two rotational motion.

# 4 servo motors are to give:
1. Rotational motion to the base of robot
2. Rectilinear motion to lower arm
3. Rectilinear ...

Egor v.2 can track movement and respond to questions via a wireless keyboard. However, voice recognition can be implemented using Macs dictation and speech function in system preferences in-putted via the Xbox Kinect's internal quad mic set up. The robot uses an adapted version of the Eliza algorithmic framework (Siri derivative) to respond to participant questions, The 'script' is then out-putted to Apple scripts' voice modulator so it can be heard through the robot's internal speaker system.

The application of the project is as an interactive exhibit, but this project is highly adaptable and would be suited for museum displays, help desks or interactive theatre. The Eliza framework can be changed to mimic any individual or language (currently based ...

In an emergency, time is critical. Whether it is a fire, kidnapping, robbery or disaster Emergency Response teams need to be present in seconds and minutes can cost people their lives. On the other hand, if a firefighter or police officer doesn’t take time to assess the situation it can cost them their life along with others and make a challenging situation worse. That is why it is important to have not only back up but also a pre-response team, that’s where Emergency Response Drones (ERD) are critical.

When a fire across town during peak traffic hours keeps your emergency responders stuck for minutes at a time a drone can be sent from the fire truck or nearby fire station ...
