ROBOTICS CLUB 2024-25
REPORT- 23 rd November 2024
Venue- XA, XB and XC
The fifth activity of the Robotics Club was held on 23 rd November 2024. The club members along with the teachers assembled in Std. X classrooms for the activity. Resource persons from the TinyBots conducted the activities for the students.
The activities of the Robotics Club were held at three levels:
Level 1
Activity: Solar Car
Solar power works by converting energy from the sun into power. There are two forms of energy generated from the sun for our use – electricity and heat. Both are generated through the use of solar panels, which range in size from residential rooftops to “solar farms” stretching over acres of rural land.
Solar cars combine technology typically used in the aerospace, bicycle, alternative energy and automotive industries. The design of solar vehicles always emphasizes energy efficiency to make maximum use of the limited amount of energy they can receive from sunlight.
A Solar car charges the battery using sunlight and solar panels. It can be used for transport. Most solar cars are designed for solar car racing. A solar car depends on a solar panel that uses a photovoltaic (PV) cell that converts sunlight into electricity.
Working:
The Solar panel generates electric current when kept in sunlight. This electricity is fed to the geared motor which drives the set of wheels connected to it on either sides. By swapping the wires at motor end we can make the car work both ways i.e. the front wheel drive (FWD) and the rear wheel drive (RWD). It can also help in pushing and pulling the vehicle, with rear- wheel drive pushes the vehicle forward from the rear wheels while a vehicle with front-wheel drive pulls the vehicle forward from the front.
Level 2
Activity: JCB/Hydraulic Arm:
Hydraulic arms can be used in situations that are too difficult or dangerous for people to deal with directly or in automated systems. Examples include arms that lift heavy weights and arms that hold a load and unload them into a specific position.
Working:
The hydraulic crane commonly known as JCB works on Pascal’s law (hydraulic pressure). It states that the external pressure applied to a fluid in a closed vessel is uniformly transmitted throughout the fluid. In this model the fluid (water) is pushed in a syringe which in turn tries to find space and hence moves anything which comes in its path.
Level 3
Activity: AI based voice controlled robot using Arduino The goal of a Voice Controlled Robot is to complete a task by listening to the user’s commands.
Text received via Bluetooth is forwarded to the Arduino Uno board using UART serial communication protocol. Arduino code checks the text received. Whenever the text is a matching string, Arduino controls the movements of the robot accordingly in forwarding,
backward, Turning Right, Turning Left & Stop.
Working:
The Arduino Robot is the first official Arduino on wheels. The robot has two processors, one on each of its two boards. The Motor Board controls the motors, and the Control Board reads sensors and decides how to operate. Each of the boards is a full Arduino board programmable using the Arduino IDE.
The connection between the android app and the robot is facilitated with bluetooth technology.
The speech is received by a microphone and processed by the voice module. When a command for the robot is recognized, then voice module sends a command message to the robot’s microcontroller. The microcontroller analyzes the message and takes appropriate
actions Students actively participated in the activities at various levels and were thrilled to see their
robots working as per their instructions.
It was a great hands-on learning experience for students.
