Motion-Controlled RC Car
Abstract
The Motion-Controlled RC Car will allow inexperienced users to drive a high-performance RC vehicle. This is accomplished with a tilt controller, which is more intuitive than a traditional RC transmitter, and a speed-limiting system that will reduce the potential for crashes.
Objectives & Introduction
Show list of your objectives. This section includes the high level details of your project. You can write about the various sensors or peripherals you used to get your project completed.
Team Members & Responsibilities
- Shangming Wang - Mesh Communication, Report writing,
- Daniel Khawaja - Wheel speed capture, RC car maintenance
Schedule
| Week# | Date | Task | Actual | Problems |
|---|---|---|---|---|
| 0 | 4/10 | Obtain hardware | Completed 4/5, excluding purchase of wheel speed sensors. | The base car (purchased used) required quite a few replacement parts |
| 1 | 4/20 | Find PWM parameters, Test mesh communication | PWM: 4/15 Mesh: pending | The servo and speed controller use pulse length instead of duty cycle |
| 2 | 4/27 | Implement PWM control, Finalize mesh communication, Test code for wheel speed capture | PWM: Mesh: Capture: | Problems Encountered? |
| 3 | 5/4 | Implement motion control, Modify RC for 2wd and mount wheel speed sensors | Motion: Modification: | Problems Encountered? |
| 3 | 5/11 | Finish wheel speed capture, Test and polish traction control parameters | Capture: T.C.: | Problems Encountered? |
| 3 | 5/18 | Study for finals, Implement extra features | Completed? hopefully. | Problems Encountered? |
Parts List & Cost
| Qty | Description | Total Cost |
|---|---|---|
| 50 | Jumper Wires | $3.00 |
| 1 | Prototype Board | $1.00 |
| 1 | Turnigy 500mAh Battery | $40.00 |
| 2 | Wireless Antenna | $6.00 |

| 2 | Motorola MOC7821 Photo Interrupter | $4.00 |
| Total Cost | $364 |
Design & Implementation
Hardware Design
Our hardware design began with interfacing the Sj-One board with the servo and motor controller controller that were built into the model car. The motor controller included a 5v regulated output, so that was used to power all the electronics on the vehicle.
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
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?
Project Video
Upload a video of your project and post the link here.
