| Once the team had researched all available possibilities which appealed to the group in terms of the structure of the robotic drawing device and and the type of input that would be used to command the robot, the group could then compare them against each other in terms of advantages, disadvantages, the parts used for construction and the cost of the materials. These construction and input methods appealed to the team as they instantly took the interest of every team member, they were aesthetically pleasing stationery and when in motion, they were challenging so that the team could gain a sense of satisfaction when completing the project and they all would provide a good service to our customers. Tables 2 and 3 were created to collect all of this information for an easy comparison on all subjects. | Once the team had researched all available possibilities which appealed to the group in terms of the structure of the robotic drawing device and the type of input that would be used to command the robot, the team could then compare them against each other in terms of advantages, disadvantages, the parts used for construction and the cost of the materials.

| | Arm {{:robot_arm.jpg?200|}} | The robotic arm would be simple to construct. Many different materials can be used which gives a variety of options. The robotic arm design is aesthetically pleasing in the way it moves and performs tasks if constructed properly.| The materials that are used for the construction of the arm can be expensive to purchase from local providers. If not constructed correctly, the movement of the arm can be sudden and jittery. The arm can only reach a certain radius when in use.| Meccano, MeArm, 50/100 € | http://www.makeblock.cc/mdrawbot-kit/| | | Arm {{:robot_arm.jpg?200|}} | Easy to build.

| | Wheels {{:wheels_robot.png?200|}} | The wheeled construction of the drawing robot can operate over a large area on a flat surface. The base would not cost very much to buy or construct along with the electronics. The base is simple to build with the correct components. The Arduino board would be easy to program for the functions the robot is to carry out. With the wheels, the device can move freely around a plane.| The wheel method can also be less precise when in use compared to the arm and other methods. One of the drawbacks of the wheel method is that changing the colour of the pen could prove to be difficult.| 2 wheels, 3 motors, 23,28€ €|http://www.makeblock.cc/mdrawbot-kit/| | | Wheels {{:wheels_robot.png?200|}} | The wheeled construction of the drawing robot can operate over a large area on a flat surface.

| | Vibration {{:vibrating_robot.jpg?200|}} | The vibration technique for the robot could turn out to be easy to make and relatively cheap.| The vibration of the device causes it to be unable to continue in a single direction steadily. It is almost impossible to control the movement of the device. The device has extremely random movement which would not be suitable for creating art.| Vibration motor, 13 €|http://www.instructables.com/id/Drunken-drawing-robot-/| | | Vibration {{:vibrating_robot.jpg?200|}} | The vibration technique for the robot could turn out to be easy to make and relatively cheap.| The vibration of the device causes it to be unable to continue in a single direction steadily.

| | Spider {{:spider_robot.jpg?200|}} | The spider device can cover a vast area of a plane if long enough strings are used. This method can be used on a horizontal or vertical plane.| Drawing in the corners of the page could prove difficult. If a four string system is used then it would be hard to calculate the length that some strings would need to contract or expand.| Motor x4, Pen holder, Strings x4, System to attach at end of canvas, Microcontroller, 14 or 28 € |http://www.makeblock.cc/mdrawbot-kit/| | | Spider {{:spider_robot.jpg?200|}} | The spider device can cover a vast area of a plane if long enough strings are used.

| | Printer {{:printer_robot.jpg?200|}} | The printer drawing robot can provide a good level of precision. The drawing time will be decreased if many of the same drawings are to be printed.| The construction of this robot would be very complex. The cost of the materials could be increased as at least 3 motors would need to be purchased.

| After comparing these sets of methods of construction of the drawing robot and the way in which it receives a command, a final decision could be made on what direction the project would be heading in. | After comparing these sets of methods of construction of some drawing robot and the way in which it receives a command, a final decision could be made on what direction the project would be heading in. |

| The robot structure that the team decided on using was the wheels method in which the device can move around on a plane on wheels with a pen attached to the front of the device. The team decided this was the best solution for the task as the device can draw over a large area on a plane. The base of the robot would be easy to build and relatively cheap to buy the parts for with the correct components. The programming of the robot would be easier than that of the other options and with the wheels, the device can move freely around the paper. The materials for the whole robot would be within our budget as well which may not have been the case for other options. | The robot structure that the team decided on using was the wheels method in which the device can move around on a plane on wheels with a pen attached to the front of the device.

| It was also decided that sound would be the best option for the input to command the robot. This is the best option as it can be used by people of all ages and fun can be had when using the system to create drawings. Also, if the user is able to create their own commands for the robot then this can add to the feeling that they have created something special. | It was also decided that sound would be the best option for the input to command the robot.

| The next chapter to be discussed is that of project management and how the project manager must handle all aspects of the project from defining the project scope to the planning of each part of the project. | The next chapter to be discussed is that of project management and how the project manager must handle all aspects of the project from defining the project scope to the planning of each part of the project. |
| In Project management defining the project scope is the most important part. If it is not clear what has to be delivered to the customers in the end and what the boundaries are, the chance of failure will be high. In most of the instances, there actually is no chance to success with this unorganized approach. | In Project management defining the project scope is the most important part.

| The decided target group and potential market are children. Within children the design is more specifically for girls. The idea behind this is to pick up on the trend to make technology more attractive for females. It is important to have more incentives for girls to get interested in technology such as robotics. The drawing robot will be sold as a toy for kids to get creative. In the following chapters you can read more about the research we have done regarding this aspect. | The decided target group and potential market are children.
