Projekt template Embedded Systems WS2019/Initiale Anforderungen

Initial Requirements

• Req_01: Microcontroller should be able to operate all the sensors and actuators.

• Req_02: Surface of the Product should provide an accurate goods placing.

• Req_03: The Product should avoid collisions.

• Req_04: The Product should be able to find the delivery goal point and wait there until a new delivery request is received.

Stakeholder Role

• (R01) Developer : He should choose the components, write the software and assembly the end Product/Prototype.
• (R02) End User : End User can be Receiver or Sender of goods. He will request the service (Send or Receive).

Milestones

• (M01) Interface and control of Sensors and Actuators.
• (M02) Assembly of the Product.
• (M03) Development of the functionality algorithm.
• (M04) Boot can deliver a good to a designated location.

Requirements and Milestones

f = functional, nf = not functional

• (Req_01, nf) : Microcontroller should be able to operate all the sensors and actuators(M01)
• (Req_02, f) : Surface of theProduct should provide an accurate goods placing.
• (Req_03, f) : The Product should avoid collisions (M01, M03).
• Req_04, f): The Product should be able to find the delivery goal point and wait there until a new delivery request is received(M03, M04).

Tests and Simulation

• Hardware:
  • Ultrasonic: Read the Distant and check against a physical distant measure.
  • Motors: Monitoring of direction and speed of rotation.
  • Color Sensor: Check against the two color used with variation of the environment light.
  • Reflective Optical Sensor: Check against a line by moving the two sensors to left and right of the line.
  • Assembly and test again every single sensor/actuator.

• Software in Assembly Product and test scenario:
  • Design the Matrix where the Product should work.
  • Test if line can be followed.
  • Test if Rotations are accurate.
  • Test if Obstacle can be detected.
  • Test if Colors can be detected.
  • Test if a delivery without obstacles can be done.
  • Test if a delivery with obstacles can be done.
  • Change test scenario and repeat.
