# Robot control from the remote control

To control the robot with the [remote control](/en/gamepad/about.md) you need to write a program and run it on the robot.

## Example of interaction with the remote control

1. Write [an algorithm](/en/gamepad/remote-control.md#program-algorithm) to use the controller in TRIK Studio.
2. [Connect](/en/trik/wi-fi.md) the controller to the computer and [upload](/en/trik/run-upload-programs.md) the written program to the robot.
3. Connect your smartphone to the controller by selecting the controller's network.
4. Open the [TRIK Gamepad](/en/gamepad/about/app.md) app on your smartphone.
5. Execute the algorithm on the controller.

## Program algorithm

1\. Enter variables for gamepad touch coordinates - `x` and `y` - and initialize them by assigning zero values to them in the "[Expression](/en/studio/programming-visual/blocks.md#expression)" block:

2\. Add the "[Wait for Gamepad Connect](/en/trik/programming-visual/blocks.md#wait-for-gamepad-connect)" block:

3\. To check if the gamepad clicks on the left area (Pad1), add a "[Condition](/en/studio/programming-visual/blocks.md#condition)" block with the condition [`gamepadPad1Pressed`](/en/trik/programming-visual/sensory-variables.md#gamepadpad-1-pressed-gamepadpad-2-pressed)`> 0`:

4\. In case there is no touch, it is necessary to stop the motors. To do this, add a block "[Stop motors](/en/trik/programming-visual/blocks.md#stop-motors)":

5\. If the [Pad1](/en/gamepad/about/app.md) area is pressed on the gamepad, you need to get the coordinates of the touch. To do this, use the [`gamepadPad1`](/en/trik/programming-visual/sensory-variables.md#gamepadpad-1-gamepadpad2) array in the "[Expression](/en/studio/programming-visual/blocks.md#expression)" block:

6\. After getting the coordinates, add a simple controller with the "[Motor Forward](/en/trik/programming-visual/blocks.md#motors-forward)" blocks. The Y coordinate offset is responsible for the speed of the robot and the X coordinate offset is responsible for the rotation.

7\. To close the condition, add a "[Timer](/en/studio/programming-visual/blocks.md#timer)" block with a value of `100 ms` (in the program this is the time for a new call to the remote control).

8\. Close the loop on the "Condition" block with a link from the "Timer" block.

9\. If you have a video camera, add the "[Enable Video Streaming](/en/trik/programming-visual/blocks.md#camera-on)" block to the beginning of the program:
