Wireless Humanoid Bionic Arm on Robotic Vehicle

 This system has two wireless controllers mounted on gloves, one for each hand of the operator. Here system precisely replicates the finger motion of one hand of the operator onto the motion of the humanoid arm. The RF receiver is interfaced with microcontroller to control the driver IC which is responsible for controlling the movement of the arm. The transmitter circuit consists of an accelerometer sensor which is interfaced to atmega microcontroller. This transmitter circuit sends commands to the receiver circuit which indicates whether to move the robotic arm in any directions or whether to grip an object or release it. Also using the hand gestures of the other hand of the operator, motion of robotic vehicle is controlled.

 LIDAR based Self Driving Car Delivery Robot For Food & Ecommerce

ABSTRACT

This is the generation of robotics and automation, moreover COVID pandemic has increased the need of touch free interactions. So to boost ecommerce and food deliveries without the spread of infections due to human contact we here propose an autonomous delivery robot system. The robot is designed with raspberry pi board to ensure the complete robot working. The robot is controlled by a 4 wheel drive and remotely controlled via a RF remote. Also the bot has an upper section to carry packages on it that can be opened only by intended recipients. This anti theft mechanism eliminates the risk of any robot thefts and ensure human like delivery. Also the robot is equipped with a ultrasonic sensor to avoid dashing into people or objects. The control team monitor the robot direction via a remote camera to easily navigate the robot. And check for any theft attempts. The robot consists of a speaker to interact with customers and make a sound to alert them to open the door when bot arrives. Also the speaker is used to make noise if a theft attempt is made along with a siren system.

The bot is able to deliver food and packages upto 10 kg using its powerful 4 wheel DC motor drive system. The  control with long range camera allow it to deliver as well as thwart any theft attempts using the on board siren system.

 Voice Activated Automatic Self Folding Dining Table

Introduction

Dining tables are used only during lunch and dinner, yet they occupy large spaces in a room for the entire duration of day and night. There are some folding dining tables but manually dragging the dining tables, then unfolding and folding dining tables manually 2 times a day is a strenuous task.

Well what if the table could automatically move itself to the centre of the room and then unfold itself when you tell it to? Also automatically fold itself and move itself to the corner of the room to act as a side table on your command. Well such tables are not just a future concept now that we design an automatic dining table with the exact functioning as mentioned above.

Mechanism

The self-folding and unfolding dining table makes use of dual motor drive along with IR Sensors and dual motor folding and unfolding mechanism to achieve this operation. The system is integrated with a controller based speech recognition system to enable the open and close operation via spoken commands.

When user instructs then dining table to open the command is captured by the controller mic and processed. Now the system checks for obstacles on both sides o divide which side to open on. If the user command said open the table half, the machine will only open half table on the open side. It user command says open full then the table will move itself on the pen side and then open both the sides to serve as a full dining table.

This unfolding processes activates the motorized mechanism that uses a geared arrangement to move a connected rod to drive another support rod with a wheel arrangement to push the sides of the table into a horizontal alignment parallel to the centre table plate. This mechanism allows to open the table on both or any one side as needed.

The same mechanism is used to unfold the table and move back to the wall itself after folding so that it frees up the space. Also the unfolding happens simply on users commands, all user needs it to ask the dining table to close itself.

Abstract

It is an pneumatic device that helps individuals who have weakness in the muscles of the hand and individuals who carry heavy things constantly by means of a supportive structure for the hand and the back contains clamps from the front to hold things and lifts heavy loads according to what is permitted in the design and moves in a circular motion With the movement of the forearm of the hand to facilitate the transfer of loads and the work of blindfolds on the back (ribs) so that the weight is focused on it and avoiding loading on the spine, and a ground holder is designed for it in the event of very heavy weights to be installed and a large part of the load is focused on the ground such as The idea of the crane and the work of bearing the limbs is done by means of a joystick that has directions and there are buttons to control the arm manually in addition to the sensors

introduction

As a result of the scientific and technical progress in which we live now, we must use it to relieve people and make them feel more comfortable and preserve their health and life more.

Therefore, robotics companies and artificial intelligence are rushing to manufacture devices that allow people to live in more comfort.

Project aims

1- Helping people with weak muscles.

2- It helps those who have muscular dystrophy in carrying out their daily tasks as a minimum.

3- It is used to transport very heavy things.

4- It can be developed and a supportive position for the foot also helps those who cannot move.

5- Enlarge the size of the body and make it carry heavier things.

Project

Links and form:

The shirt sleeve is designed with ties that allow the hand to move in a Y direction and the shoulder can rotate around the z axis.

The biceps and tarsal muscle area has a fixed part parallel to the human body and is fixed by it from the top of the hamstrings or piston that work with pneumatic that will engage you in the movement of the other part of the hand and the rotation in the upper part is done using an electric DC motor connected to a gearbox

The back consists of circular carriers that help distribute the reddened weight, and

there is more than one belt on the back, shoulder and hand, and the devices accompanying the movement of the arm are installed.
