Hand-operated robots from toys become learning media

In childhood, many people would be happy to have fun playing with various kinds of things. Many pieces were played until stuck. play all day One of the boy’s all-time favorite toys is Wired controlled car, press the front ground, press backward, press to run left, go right, just seeing the car running back and forth is fun At that time, I didn’t think I would get anything after playing. Just having fun is enough

How does a forced car work?

There’s not a lot of components in the wired car, just the motor, gear reducer, battery, wheels, push-buttons to move forward, backward, turn left, turn right, all put together. By using simple electrical principles, do not hold the spoon from the picture when pressing the upper switch The top motor will rotate When the lower switch is pressed, the lower motor rotates. If two switches are pressed at the same time, the motor will rotate at the same time. but rotate in opposite directions with such principles We can now build a simple wired remote control car.

Transform a car into a robot

A robot, or robot, is a type of machine. There are different structure and shape. Each type of robot has different functions under direct human control. Controlling various systems in order to operate between robots and humans. Can be done by human beings to control and operate automatically. Robots are generally built for difficult tasks instead of humans. By definition, we can press the switch to make the car go forward, turn left, turn right, so that it works either way we want as well. If the task is clearly assigned to the car. We can call it The car also acts as a robot. one type is the same.

Simple hand operated robot circuit

From the simple electrical circuit of the wired control car, we can further improve the electrical circuit a bit. It will have a hand-controlled robot circuit that has increased capabilities. Forces forward, backward, slow turn, right turn, as well as agile backward and left or right turn. and support better control

Caution Because the circuit is designed to be easy to assemble, there is no short circuit protection system. During the control, be careful not to press more than 2 buttons at the same time, it will cause a short circuit. This will cause the battery to overheat and shorten its lifespan.

The controls consist of a battery. and control switch The drive part has only a motor that is reduced to a low speed for easy control. The two sections are connected by three small wires and should be at least 2 meters long.

The robot must have a role

The car can be a robot, it has to be assigned a mission to work on one. Therefore, to be a complete hand control robot. Further developments are needed to enable the robots to perform their assigned tasks efficiently, for example if a robot is required to have the ability to move objects from one place to another. The objects that the robot must move are cylindrical. Until now, robot developers will have to analyze their assigned tasks and design the structure of the robot to suit the given task, which may have grippers. or hooks depending on the design These are processes that require critical thinking and problem solving skills.

to be fun to compete

Competition is one of the ways to encourage learning fun. For example, the rules of the competition are for the robot to move as many objects as possible in a given time. Or to move objects from the opposing team’s area to their own area as much as possible in the specified time. when there is a race Teams participating in steep races know the rules, see the field, see mission objects. The team will have to analyze. to develop robots To suit the rules and plan the race to lead to the next victory.

From the picture when everyone knows the rules of the competition, Each team began to analyze the problem. what the robot must do Divide the duties of the team members to plan the play. including choosing the right materials to use in the development of robots This may be a general waste material. And finally, be able to present the concept of robot design.

What have you been able to play?

Finally, it can be seen that From the toys that we had fun playing in childhood It can be used as a teaching aid that will help develop skills in many areas as well as make you know how to apply the knowledge in the classroom to be useful in daily life.
