2.5 Solutions for Defined Problem Definitions:

Concept 1 -

Description:

  1. The machine is used to collect waste and it will be dumped in the waste box.
  2. Through the radio waves transmission, the robot is autonomously controlled.
  3. It has sensors that can detect the waste and the weeds.

Concept 2 -

Description:

  1. Waste detector detects the waste and opens the collector wall then collects the waste.
  2. Mesh removes extra water from the collector.
  3. When the collector was filled then the sensor gives information to the user.

Concept 3 -

Description:

  1. Detects obstacles.
  2. Moves over the waste to collect.
  3. Is highly mobile.

Concept 4 -

Description:

  1. The robotic arm of the machine collects the waste and dumps it in the collector.
  2. The cost of the robot is not too expensive.

The best concept is : Concept 3

Justification:

Design 1

Objectives Score Given Justification
Effectiveness - Its not effective than the datum because the cutter and collector are small
Assembly + It is easy to assemble than the datum because of less moving parts
Cost + It is cheaper than the datum because it is less expensive to assemble
Portability + It is very small compared to the datum
Safety + It appears to be safer than the datum because the size of the cutter is small

Design 2

Objectives Score Given Justification
Effectiveness - It is not as effective as the datum
Assembly + It is easy to assemble than the datum as it has less moving parts
Cost - The machine cost is less because no usage of standard parts
Portability + The machine is small compared to the datum
Safety + The machine does not harm the aquatic animals

Design 4

Objectives Score Given Justification
Effectiveness - Since the robotic arm for collecting waste is not that effective
Assembly - It is not easy to assemble because it has many moving parts
Cost - It is more expensive than the datum
Portability + It is more portable than the datum
Safety + It is more safe than the datum
