ROBOTICS CLUB 2024-25
REPORT
The first activity of the Robotics Club was held on 27th April 2024. The club members along with the teachers assembled in the Std. X classrooms for the activity. Resource persons from the TinyBots conducted the activities for the students. TinyBots is an initiative of ES Solutions pvt. Ltd. who believe in making students curious about Science.
Objective:
To facilitate students to understand, design and learn Robotics. Provide interested students with opportunities to express their skills, knowledge, and creativity through conceptualizing, designing, and programming robots. The objective of the robotics field is to create intelligent machines that can assist humans in a variety of ways.
This year too, the Robotics Club received an overwhelming response from the students. 76 students enrolled for the Club for the year 2024-25.
The activities of the Robotics Club were held at three levels:
Level 1 –
Activity 1 : Making of a DC motor
The students of Std. VI made a DC motor. It is an electric motor which converts electric energy into mechanical energy. It works on the principle that when an electric current is passed through a conductor placed normally in a magnetic field, a force acts on the conductor as a result of which the conductor begins to move and mechanical energy is obtained. Here the copper coil is the current carrying conductor.
Activity 2. Light-Up Card
A fun way to explore electronics is by making this light-up pop-up card. This project is a great way to learn about circuits while making a gift for a friend or to celebrate your favourite holiday. The students made light emitting diode (LED) which is a semiconductor device that emits current is passed through it. LED’s are used in traffic lights, remote controls, bulbs, advertisement boards, TV displays etc. Here the students made a simple circuit with LED, copper tape and a 3V cell. When the card was opened the LED dis not glow as the circuit was open and the current did not flow. When the card was closed and pressed slightly at the bottom right corner, the vertical copper track on left side got in touch with the top face (+) of the cell. Thus the circuit was completed and the current passed into the LED leading the card to glow.
Level 2-
Activity 1: USB Table lamp
USB stands for “universal serial bus”. The USB port of our laptops/desktops provide 5V output. We have connected 6 LEDs in parallel by connecting their positive legs together and the negative legs together.
The 5V output from the USB port has been used to power up the LEDs.
Kindly note that the positive and negative legs/wires should not come in contact or else the LEDs may fuse.
Activity 2: Light sensor card
A light Sensor card checks light intensity of the surroundings and accordingly adjusts the brightness of your mobile screen. The students observed the black dot near the front camera of the smart phone. This black dot is nothing but the LDR. It is also known as Light dependent Resistor or Photo resistor. The students understood the working and application of Light sensor card.
Level 3-
Activity 1: Circuit implementation on Breadboard:
A breadboard is a solder less device for temporary prototype with electronics and test circuit designs. Most electronic components in electronic circuits can be interconnected by inserting their leads or terminals into the holes and then making connections through wires. It has many tiny sockets (called ‘holes’). The leads of most components can be pushed straight into the holes. ICs are inserted across the central gap with their notch or dot to the left.
The students made the circuit on the breadboard by inserting the component ends in the holes. They used the jumper wires provided. Jumper wires are simple wires that have connector pins at each end, allowing them to be used to connect two points to each other without soldering.
Activity 2: Arduino based LED blinking/sequence:
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs values from sensors and turn it into an output – activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing. There are different types of Arduino boards available like lilypad, nano, UNO, mega etc. The students learnt the working of Arduino based LED blinking board.
The students thoroughly enjoyed the activities at various levels.
