Wireless Tilt Controlled Camera Arm

Abstract

For this camera system, the camera moves along a track according to user’s controls. The controller, which will be one of the SJOne boards, will control the direction of movement of the camera along the track. The camera will be mounted on a track and will be connected to the second SJOne board. The camera’s movement speed is set. However, the camera’s direction will be determined by the angle in which the controller is tilted. The camera’s tilt speed will be tracked using the attached SJOne board’s accelerometer and used in the movement of the camera’s vision. Similar to the movement of the human eye, the camera in this camera system will be able see 180 degrees in all directions in forward vision. The camera can look at an angle in any direction such as left, right, up, and down. The camera can be stopped or turned off by pressing a button on the controller. If the controller is tilted 90 degrees vertically, then the camera will start moving in that tilted direction. If there is an error, the user can press a button on the controller that will stop receiving accelerometer data from the controller board and the camera will reset back to the center position of the track and the camera will be back to facing the correct orientation. Data is transferred through wireless communication between the two SJOne boards.

Parts List & Cost

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

Part Name Model Number Quantity Cost (Total) Notes
Microcontroller SJOne Board 2 $160 One for Main Wireless Controller and One for Camera Motion Controller
2.4GHz 6dBi Indoor Omni-directional Antenna Antenna 2 $9 Used for wireless communications between the boards
Osoyoo Micro Servo Motor SG90 10 $20 Used for the motor control for the arm
High Torque Metal Gear Feather Servo Motor HS-5065MG 2 $54 Used for the motor control for the arm
5V Step-Up/Step-Down Voltage Regulator S18V20F5 1 $15 Used for regulating power to the SJOne Board
6V Step-Up/Step-Down Voltage Regulator S18V20F6 1 $15 Used for regulating power to the motors

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.

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.

Figure 1. Our Overall Project Software Design

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.

Board-to-Board Wireless Communication

The board-to-board wireless communication utilizes Nordic Wireless on the SJOne board. Initialization of the SJOne boards' wireless features was mostly handled by the default wireless task. For wireless communication, the wireless channel number used by both boards must be the same. The two boards used in this project each had their own wireless node address, which was used to uniquely identify each of the boards during the wireless communication. Two additional tasks were created to perform the intended operations needed in this project: one task for wireless data transmission and one task for wireless data reception. The main wireless controller performs the task that transmits data while the camera motion controller performs the task that receives data. The transmit task first interprets and uses the acceleration data captured by the SJOne board's acceleration sensor to generate the appropriate instructions to send to the camera motion controller. Then, after the instructions have been generated, the transmit task packages the instructions into a packet and sends the packet wirelessly to the other board. The receive task receives the wireless packet and unpackages the packet to obtain the instruction data. Then, the receive task uses the instruction data to control the movement of the motors.

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

Initially, as we were testing the board-to-board wireless communication, packets would often be lost during the transmission. In order to resolve this issue, we reduced the air kbps rate down to provide a more stable signal. Although reducing the air kbps rate did reduce the loss of packets, the data transmission rate became much slower.

My Issue #2

Discuss the issue and resolution.

My Issue #3

Discuss the issue and resolution.
