They say that robots are coming for our jobs…well, let them. If you cannot beat them, just join them. Let us ask the serious question, what are robots? Everyone thinks of them as machines that can run autonomously. They complete complex tasks that have been programmed by a computer. It, therefore, applies that dishwashers and thermostats are robots.
If you get the deeper meaning of the word “robot”, any object that can be remote controlled, can be classified, as a robot. Remote-controlled robots have become the talk of the town, as it is a huge industry. More people are becoming fans and love to play with the so-called robot toys. This, largely, might be because it is easy to make your own remote-controlled Robot Toys, or in short, RC Robot.
First off, understand that you will be building a small robot and not the humongous device that can pick up heavyweights. Work with a small robot and modify it with time. Once you agree with your heart and mind about this part, understand what you want to build. Come up with a plan for the robot. Plan to build a simple and small robot that can get an upgrade later. Use a pen, ruler, and paper and sketch the robot of your choice. If need be, use computer programs or consult Google SketchUp to sketch one.
Next comes the difficult part, of choosing the parts you will use. You need a material for the chassis, a battery, two servo motors a transmitter and a receiver. The two servo motors are to be used to power each wheel. A servo motor can be geared and can turn the device 180 degrees. As well, as transmit data back on the device’s position. Consider a servo motor’s speed, size or weight, torque and if it can be modified. Get motors that are average-sized; one that has average torque (motor strength), since the higher the torque, the lower the speed. Balance the two.
Get a DC battery. Most batteries operate with the majority of the servo motors but get one that specifically allows the motor to go faster and have motor power. It is recommended that you grab one with 6.0V. Then check the batteries’ capacity, labeled as “mAh”. The higher the capacity, the better, although the more expensive they get. A 6.0V 2000mAh NiMH battery is preferable.
For a beginner, get a HDPE material as compared to aluminum or plastic. Now, for the expensive part, choose the perfect receiver or transmitter. Choose one that can be modified in the future, so do not go for the very cheap ones. Finally, choose wheels with a greater diameter, preferably 3” – 5”, rubber or foam ring and wheels that can be attached easily. Once you have chosen the parts, order them and get ready to make your first robot.
Measure the pieces and cut them as per your dimensions. Confirm that they are not crooked, so be very careful. Take the time to measure, than to cut them. Now that you are done with that, assemble the robot. Mount the servo motors, attach the wheels, stick the receiver and the battery pack on both Velcro and you should be ready.
Plug the robot into the receiver in order to charge the battery. Plug the servos into the first two channels on the receiver. Charging could take a while, so be patient. Once it has completely charged up, you are ready to go and you officially will be using your personal robot to perform the tasks it has been created to do.
It is not a tough task to make your own robot toy. All it takes is guts and some little bit of money in order to acquire the pieces. The method is not complicated and at the end of it all, you will have your own DIY robot that you can play with at any time. The better news is that once you perfect the method, you can modify or build a better robot with time.
