Abstract

The project aims to build a motorized camera holding bot that helps the photographers to create moving time-lapses across a landscape.The photographers can program the bot to move in a sequence of desired directions and capture the time-lapse. CamBot can slowly move over time to capture the time-lapse and also slowly change angles.

Objectives & Introduction

The project explores the GPIO and UART drivers in LPC1758 platform. CamBot is driven with the help of DC Motors whose PWM Signals are given by LPC1758. Since stepper motor moves in precise repeatable steps, it is best suited for applications requiring precise positioning. Precise increments of movement also allow for excellent control of rotational speed for process automation and robotics. Normal DC motors do not have much torque at low speeds. The sequence of directions for the CamBot is provided by a Bluetooth Application which sends the commands for specific movements.

Parts List & Cost

Give a simple list of the cost of your project broken down by components. Do not write long stories here.

Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Hardware Design

Discuss your hardware design here. Show detailed schematics, and the interface here.

PCB Design

PCB Schematics

PCB Board

• 

  PCB without Components
• 

  PCB with Components
• 

  PCB with Motor Driver

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Software Design

Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

Implementation

This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

Testing & Technical Challenges

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Include sub-sections that list out a problem and solution, such as:

My Issue #1

Discuss the issue and resolution.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
