Robot Escape Room

Robot Escape Room

1. Task Requirements

   • Prescribed criteria
     • Follow a safe path to the exit
       • Robot must stick to the given path and follow it
       • The robot must go either around the obstacle or clear its own path
       • Robot cannot cut through the path or climb over other objects
     • Use a sensor to identify any dangers or obstacles
       • Code robot to use its sensor to detect an obstacle in its path
       • Code robot to go around or clear the obstacle from its path when its sensors detect the obstacle
     • Use sensor(s) to avoid or manoeuvre any dangers or obstacles
     • Complete a room-specific challenge
       • The robot must complete the challenge set to it
   • Self determined criteria
     • Alert the user when the robot has detected an obstacle in its course
       • Use sensors to detect that there is an obstacle in the way
       • Code the robot to make a noise or s frowny face when the object is detected so the user is informed
       • Robot could back away from the object
     • Notify when it has a started its course
       • When robot starts moving flash lights to notify it has started
       • Make a beeping sound
     • When the robot has completed the course and exited and celebrate
       • The robot can make a happy face
       • The robot can display a trophy

       • The robot can play a victory sound

2. Constraints and limitations

   • Time
     • Limited to 5 weeks
   • Skills
     • Prio knowledge to block coding
     • Have not yet worked with actual robots
     • Limited skills when it comes to making the robot use different sensors
   • Robot build
     • Robot has to follow the given route and the map cannot be altered to help the robot make its way around the route
     • Robot cannt be changed or altered to suit personal preferences
     • Cannot add an extra sensors

3. Robot

   • Sensors
     • Colour sensors
       • In this mode, the colour sensor can differentiate eight different LEGO colors. Each LEGO colour is also represented by a value. The sensor can also output the raw red, green, and blue (RGB) values separately.
       • Light
         • Reflected light
           • In this mode, the colour sensor emits a light and measures the amount reflected back into itself from the surface you are testing. The intensity of the light is measured as a percentage from 0 to 100, with 0 being very dark, and 100 being very bright.
         • Ambient light
           • In this mode, the colour sensor measures the amount of light in its environment, without producing its own light source. Ambient light intensity is measured as a percentage from 0 to 100, with 0 being very dark, and 100 being very bright.
     • Touch sensor
       • The touch sensor gives the robot a sense of touch. It can detect if it is being pressed and the amount of force being applied. It measures the amount of pressure being applied to it in newtons or asa percentage.
     • Distance sensor
       • The Distance Sensor measures distance to an object or surface using ultrasound. The sensor works by sending out high frequency sound waves that bounce off any object in range, and measuring how long it takes the sound to return to the sensor. The Distance Sensor can also be used as a light source, with four LED segments around the "eyes" that can be controlled individually.
   • Large and medium motors
     • Because they are equipped with internal rotation sensors, both the medium and large SPIKE Prime motors can measure the motor’s speed and its position. Either motor can be used as an input device, reporting its position as it is rotated by hand. The motors can measure their position in degrees either as an absolute position in reference to the zero point marked on the motor, or relative to another zero point of your choosing.
