## **Bird-Watching Telescope with Real-Time Bird Identification**

### **PROBLEM:**

When observing wild birds at a distance with a handheld telescope, due to the agility of the birds, before one can carefully identify or record the characteristics of the birds (appearance and call), they often fly away, making it difficult to determine the species. A smart telescope is needed to greatly assist bird watchers, especially beginners, and provide real-time identification of birds.


The Bird-Watching Telescope is designed to help birdwatchers record the characteristics and identify the species of the bird immediately. The Bird-Watching Telescope integrates a camera, telescope, laser ranger, bird identification software on mobile phones developed by our team, and other functional circuits. Users can deploy the telescope wherever they want, and wait until a bird appears. After manual aiming and autofocus, the bird identification software will automatically identify the species of the bird.


#### **Telescope Modules :**

- The primary telescope able to tune the focus by hand, with space assigned for later electrical components beforehand.

#### **Recording, Transmission & Annotation Modules:**

- Real-time video recording through ocular lens, simple preprocessing to make it easier to transmit to mobile phone with Bluetooth.
- LCD part to play the result sent from mobile phone in the oscular lens.

#### **Identification Modules:**

- Bird identification program, including video preprocessing, visual classification, identification result annotation signals.

#### **Red-dot Focus Modules:**

- The mechanical structure that can adjust the lens spacing, and the red-dot device.
- Simple program to adjust the lens spacing with distance of the red-dot, which is put on the telescope.


- Functionality: This smart telescope can record through ocular lens, transmit recordings to mobile phone to process the identification. Identification results will be displayed via LCD screen on viewfinder and saved on mobile phone for users' convenience. An automated red-dot focus system can fine-tune the focus itself.
- User experience: The user can obtain real-time information of bird species information while keep their eye on the telescope, regardless of their previous knowledge. They may also have the telescope self-finetune the focus onto birds using red-dot.
- Environmental parameter detection: The smart telescope can get the recording of the birds from the ocular lens. For the red-dot finetune function, it can also get the distance between the red-dot and itself.
- Processing stability: The identification processing part will be done on mobile phone offline to ensure speed, while the red-dot finetune will be just process and done on the telescope.
- Program Package Update: The update can be simply done on mobile phone, which is very flexible and convenient, ready for future update when there are better programs or more bird species.

Prosthetic Control Board

Featured Project

Psyonic is a local start-up that has been working on a prosthetic arm with an impressive set of features as well as being affordable. The current iteration of the main hand board is functional, but has limitations in computational power as well as scalability. In lieu of this, Psyonic wishes to switch to a production-ready chip that is an improvement on the current micro controller by utilizing a more modern architecture. During this change a few new features would be added that would improve safety, allow for easier debugging, and fix some issues present in the current implementation. The board is also slated to communicate with several other boards found in the hand. Additionally we are looking at the possibility of improving the longevity of the product with methods such as conformal coating and potting.

Core Functionality:

Replace microcontroller, change connectors, and code software to send control signals to the motor drivers

Tier 1 functions:

Add additional communication interfaces (I2C), and add temperature sensor.

Tier 2 functions:

Setup framework for communication between other boards, and improve board longevity.

Overview of proposed changes by affected area:

Microcontroller/Architecture Change:

Teensy -> Production-ready chip (most likely ARM based, i.e. STM32 family of processors)


support new microcontroller, adding additional communication interfaces (I2C), change to more robust connector. (will need to design pcb for both main control as well as finger sensors)


Addition of a temperature sensor to provide temperature feedback to the microcontroller.


change from Arduino IDE to new toolchain. (ARM has various base libraries such as mbed and can be configured for use with eclipse to act as IDE) Lay out framework to allow communication from other boards found in other parts of the arm.
