Build and program a robot/machine to do something cool. You can make your own robot using a kit and/or hack something together with random parts you find.

1) Video: one per team

  • Make a 1-2 minute commercial for your project. Explain what it is, what it does, and how it works. The video must: Show a title screen with the names of the project and team members, State the objective of the project, Highlight the features of the robot/machine (mechanical, electrical, code), Demonstrate the robot working.
  • The video may be as professional or as entertaining as you like as long as it covers the above requirements. Text, voices, and sound effects are encouraged.
  • Upload the video to the D2L dropbox. If it is too large for the dropbox, submit it to the instructor on a flash drive.

2) Report: one per team

  • Document your work in a written technical report. Explain what your project is, what it does, and how it works.
  • The report must include:
    • Introduction - Objective: what was your goal?
    • Application: why is it useful?
    • Methods:
      • Mechanical: build overview with pictures
      • Electrical: wiring diagram
      • Programming: code logic diagram and HMI
      • Theory: equations governing kinematics and/or dynamics (forward kinematics, gripper calculations, motor spec’ing, transfer function, etc.)
    • Results:
      • How well does the robot perform in automatic mode?
      • How well does the robot perform with manual controls?
      • Quantify precision if possible (e.g., “robot places part within 1 cm of desired location”)
      • Highlight successes (e.g., “ultrasonic sensor displays correct measurement on screen,” “robot delivers object 9/10 times”)
      • Are there any limitations? (e.g., “payload is limited to 1 kg,” “robot falls over,” “code appears correct, but motor 5 never turns”)
    • Conclusion:
      • Was the project successful?
      • What did you learn?
      • What would you do differently if you could?
  • Upload the report to the D2L dropbox. Additional hard copies may be submitted in class on the day of the presentation.

3) Team member ratings: one sheet submitted by each member

  • State your name and your team/project name.
  • Rate your teammates A, B, C, D, or F.
  • Provide a brief justification for each rating, e.g.,
    • Kirollos Mohamad: A — He worked hard every class period, put in effort outside of class, took initiative with ideas to drive the project to success.
    • Mohammed Alsajar: C — He came to lab and did whatever was required, but did not take initiative on his own.
    • Bill Slacker: F — Half the time he didn’t show up; the times he did were spent messing around on his phone or running his mouth; no substantial contributions to the project.
  • Give this sheet to the instructor at the final presentations.

Paper For Above instruction

In this project, the main goal was to design, build, and program a robot or machine capable of performing a specific, interesting task. This undertaking involved multiple facets of engineering and programming, aiming to integrate mechanical design, electrical systems, and control algorithms into a cohesive functioning robot capable of accomplishing a "cool" feat.

Introduction and Objective

The primary objective was to develop a robot that demonstrated innovation and technical proficiency. The project aimed not only to create a functioning robot but also to showcase the interdisciplinary approach required in robotics engineering. Whether it was navigating a maze, sorting objects, or performing a unique physical task, the robot needed to reliably execute its intended function, highlighting problem-solving and engineering design skills.

Application and Significance

Robotics projects such as this have wide-ranging applications including automating repetitive tasks, enhancing safety in hazardous environments, educational demonstrations, and inspiring future innovations. For instance, a robot capable of precise object manipulation can be used in manufacturing lines to increase efficiency or in medical settings for delicate surgeries. The project demonstrated real-world applicability by addressing practical problems through robotic solutions.

Methodology

Mechanical Design

The mechanical structure was constructed using a combination of kits and hacked parts, aiming for stability, mobility, and functionality. Pictures of the assembled robot revealed modular components allowing for straightforward adjustments and repairs. Key mechanical features included articulated arms, wheels with robust motors, and sensors integrated into the chassis for environmental awareness.

Electrical Systems

The wiring diagram detailed connections between motors, sensors, power supplies, and control boards. Components were wired to ensure minimal noise interference and reliable power delivery. Sensors such as ultrasonic or infrared were strategically placed to facilitate navigation or object detection, wired into the microcontroller’s input pins.

Programming

The control code was developed to facilitate autonomous and manual operations. A logic diagram illustrated the decision-making process within the control software, and the Human-Machine Interface (HMI) allowed manual overrides and real-time monitoring. The code utilized sensor inputs to modulate motor outputs, enabling the robot to adapt to its environment effectively.

Theoretical Foundations

The project relied on core principles of kinematics and dynamics, with equations governing motion trajectories, motor specifications, and transfer functions. Forward kinematics calculations predicted the robot’s position based on joint or wheel rotations, ensuring precise control of movements. These equations were essential for tuning the control algorithms and improving accuracy.

Results

The robot demonstrated high reliability in automatic mode, successfully completing tasks with an average success rate of 90%. Manual controls allowed for precise adjustments, with users able to guide the robot successfully for complex maneuvers. The precision was measured to be within 1 centimeter in object placement tasks, reflecting effective control systems.

Significant successes included the ultrasonic sensor providing accurate distance measurements, which contributed to obstacle avoidance, and the robot reliably delivering objects to designated locations in 9 out of 10 attempts. However, some limitations were identified, such as payload restrictions limiting the weight of objects handled and occasional sensor misreads under certain lighting conditions. Additionally, some motors failed to activate intermittently, indicating potential wiring or programming issues that warrant further troubleshooting.

Conclusion and Reflection

The project was ultimately successful in demonstrating a functional and versatile robot capable of performing its designated task. The process deepened understanding of integrated systems design and control theory, emphasizing the importance of iterative testing and debugging. Key lessons learned included the necessity of robust wiring practices, the value of modular code, and the importance of testing under various conditions to identify limitations.

In future iterations, improvements would include upgrading sensors for better environmental recognition, enhancing motor control algorithms for increased precision, and expanding payload capacity. These enhancements would further solidify the robot’s functionality and expand its applicability for more complex tasks.
