Lesson 1-Meet Playme

Updated: Nov 7, 2019



Our world is filled with machines and robots everywhere. Now we are using machines, robotics for many things like manufacturing any product, household appliances. In near future robotics will everywhere to do any kind of work. Playme a programmable robot is an introduction to the world of Robotics. It creates an environment to play with robotics and electronics much easier. Meet Playme a Robot For Curious minds. It is a  robot which has many things inside it. It is an educational robotics kit through which you can develop logical thinking, computational thinking, program Lets explore features of Playme one by one.

Playme an Educational and Fun Robot

Playme consists of:-


Two DC BO Motors :-  Motors along with two wheels. Here motors are used to provide movement to wheels. Speed of motor is 150 RPM.


Robotics for kids
Single Bo Motor


Caster Wheel :-  It helps robot to make smooth turns while moving.

Ball Castor Wheel

Wheels :- A wheel is a circular component that is intended to rotate on motors .Here RPM stands for Revolution Per Minutes. According to motor direction wheels will move.

Motors are having names like Left Motor, Right motor. We can move robot in forward, Reverse, Left, Right Directions.

1 Ultrasonic Sensor:- Ultrasonic sensor is commonly used for distance measurement. Here we are using HC-SR 04 sensor which can sense distance up to 400 cm. We can perform many tasks using this such distance follower robot, obstacle avoiding robot. An ultrasonic sensor is commonly used for distance measurement.
