5.5 CONCLUSION

The project was time-consuming, work-intensive and economically tasking. However, we are proud as a group to have achieved for the first time, the control of a 6-degree of freedom robotic arm, a pioneer in the department of Electronics Engineering, UNN.

From our experience, we recommend that for the future implementation of this project, the following improvements can be made:

• The robot can be fitted with wheels and adequate sensors to make movement possible.

• Control can be improved by using a remote control or joystick to manipulate the robot instead of devoting a whole computer system to it.

• The robot can be given added intelligence so that it can sense obstacles respond appropriately.

• Proper selection of integrated chips should be made and they should be thoroughly tested before purchase to eliminate chances of faulty chips being purchased.

• It is also advisable to have the arm fabrication done in a workshop with up to date machinery to avoid errors in construction.

The possibilities are endless. Robotics is a relatively untapped field in Nigeria and it has many prospects. Starting with our community, we can, step by step, create robots that will ultimately be used to perform some pertinent tasks that are too bothersome for human beings. The fact that it also combines various disciplines of engineering is also notable.

GLOSSARY

Accuracy - The accuracy of a robot is a measure of how the robot can reach a position at which it was instructed to reach.

Artificial Intelligence - This can be defined as the branch of computer science that deals with writing computer programs that can solve problems creatively.

Axis - A pivot point for a type of movement.

End-effectors - End-effectors are hand-like devices or special tools placed on the robot’s arm used to perform work. They are designed to mimic the function and structure of the human hand.

Industrial Robots - An industrial robot is officially defined by the International Standards Organization as an automatically controlled, reprogrammable, multipurpose manipulator programmable in three or more axes. The field of industrial robotics may be more practically defined as the study, design and use of robot systems for manufacturing.

Number of axes - The number of axes of robot is the number of joints required to reach any point in space.

Robot - A robot is simply defined as a device that connects sensing with actuation using a suitable computer logic, which processes the inputs from the sensors and sends out outputs to actuate devices.

It can also be defined as a computer-controlled machine that is programmed to move, manipulate objects, and accomplish work while interacting with its environment.

Robot Controller - This refers to the computer logic that controls the robot’s actions. The robot controller is a device that has, programmed in it, the instructions which are to be performed by the robot. It is also referred to as the brain of the robot.

Robotics - This is the area of artificial intelligence that is concerned with the practical use of robots i.e. robotics is the science and technology relating to use and design of computer-controlled mechanical devices.

Work Envelope - This is the region of space a robot can reach.
