INNOVATIVE WORK

INNOVATIVE WORK

As a part of our FOURTH SEMESTER INTERNSHIP PHASE II , we have to prepare two innovative  models . Here I'm presenting my innovative works. 

1. CIRBOT - A Circle drawing Robot

My first innovative work is a working model to draw circles. 

CIRBOT is a machine(working model) that helps to draw circles very easily and fast. It works similar to a pair of compasses but with the help of a motor, battery and switch.

Things you need

                    Wooden stick-3

                    Geared DC Motor

                    9V battery with cap

                    Switch

                   Circle shaped piece( like bottle cap)- for wheels

Construction

Put a hole in the Circle shaped piece at its center and place it on the rotating end of the motor. Fix it using gum. Join the ends of two wooden sticks on the motor, as they ate in perpendicular direction. Join the third stick in between them. Fix the switch on the top of the motor. Fix the battery inside the  stick . We get the motor connected to switch at a corner and the battery on the opposite stick.  

Connect the negative pole if the battery with the negative of the motor. And the positive of battery to the motor through switch. The connection are used by a battery cap. 

Fix a thin pointed nail at the corner. Attach a pen/sketch with the help of a rubber band, near to the battery. 

Fix the nail on a flat surface drawing sheet,  and  switch on. The pen will rotate through the paper as the wheel rotate. Finally we get a perfect circle. 

And the CIRBOT is ready

When I presented  in the class , I made a circle by students so that every one can see the working of CIRBOT. Some of them drawn themselves. 

2. MOVING QUADRILATERAL

My second innovative work is a working model , namely MOVING QUADRILATERAL. 

All types of quadrilaterals can be shown using a simple model. Rectangle, square, parallelogram, rhombus and trapezium : all such quadrilaterals, the properties of each sides and each angles can be learn easily.   

Things you need are

                    4 scales of 30 cm

                    4 -360 degree protractors  

                    4 nuts and bolts

Construction

Take a scale and cut out the center part(to make a small slit along the scale). Do it with all the four scales.Then connect two scales using nut and bolt,by putting one  protractor in between them. And complete the model by connecting all the four ends to make a closed form. 

By adjusting each screws and adjusting the length of sides, we can make the models as we want.  

When I presented it in my class, all the students tried to make use of it at once. All of them were very exited. It was very useful for  revision on the chapter Area of quadrilaterals.
