This is our project: garage gate. We decided to create it as realistic as possible. We used three sensors: two touch sensors and one ultrasonic sensor. All of them and also enginee are suported by Husarion RoboCore, which is situated on the back of our gate. Ultrasonic sensor detect move of any object crossing the entrace of gate and help reacting (gate stops and immeditely opens). First touch sensor detect objects under the gate (in result, it won't squash anything or anyone). Second touch sensor checks position of the gate. We also created app on android conected by bluetooth mode. You can use it to open and close the gate.
