i want to create my own robote could you help me easy way

42

i am glad .thnk you it is helpful for me

43

@merhawi The easiest way is to buy a robot kit and follow the instructions.

44

Thank you for the tutorials and kudos for the robotshop team! Question here, assuming I have a UAV, how could I make it rotate while it hover or should I say how could I make it rotate in its own axis? Thank you :slight_smile:

45

@Zero The flight controller takes care of this; the rotation of the propellers create a rotational force and when you adjust the speeds of certain propellers, that force causes the drone to rotate about its own axis.

46

Could we make a touch sensor, by programming a microcontroler, a dc motor and a rotationnary potentiomerter or stepper motor, If the motor is “on”, and the angular position does change, we could say we are touching something…

47

@zohann Essentially you’re using the potentiometer to sense a change, so sure.

48

thanks,I love robots.

I have a robot controlled cow ( 36 volt) I use to train my roping horses with. It is controlled with a rc car transmitter. I am wanting to change it to a Bluetooth or gps control so I can set up patterns for it run so I don’t need another person to control robo while I ride horse. Can I get some help or tell me where else to look. So far you are helping bunches I new to all of this.

@Tinker Even if you are planning to use Bluetooth to control your robot, you still need another person to control it via Bluetooth. You’ll need the robot cow to be autonomous. If your robot has a programmable controller, you can probably program it to realize some movements. If not, you’ll have to replace the entire controller of the robot with a microcontroller.

i like this websote

52

Thanks, I loved robots since I was a young kid ! very amazing products !

53

I like the DIY wearable robots as I enjoy using them.

54

i want to make a line controller robot to participate in the competition.plz guide me how to make it…

55

@aezaz Providing instructions for a specific application is a bit beyond the scope of this tutorial series. You might want to create a new post on the RobotShop forum and give as many details as possible (what products you already have, your budget etc).

56

I want to build robot follow person, so Do you build it ? need to prepare ?

57

@DN Take a look at the practical example in this lesson to get an idea as to how to do that.

58

haha this is so good I love to search new robots

59

What sensor would i need for a robot arm?

60

@Brandon It all depends on what you are prepared to code; normally you want a force feedback sensor so the arm does not destroy itself, and you may want a position sensor to know where the arm is in space. Additional sensors can include voltage and current feedback and even torque (or force in the case of linear actuators).
