**PROBLEM:**

With accessibility being considered more in modern infrastructure, more and more systems for accommodating people with physical disabilities are being installed every day. Most of these systems are installed in public locations and paid for by the government. However, installing similar accessibility systems in one's home for those with movement limitations is much more costly and difficult, even for such common accessibility obstacles such as doors. Cheaper and easier to install automatic doors meant for residential homes would alleviate this cost barrier and difficulty of installation for those with movement limitations that struggle to use standard, manual doors.

**SOLUTION:**

Our solution for the high barrier to entry for making one's home accessible is to make more cost effective and quicker to install automatic door conversion kits for residential homes. These kits would include a Bluetooth door opener, door handle, and remote. The Bluetooth door opener would attached to door you're converting and its frame, allowing it to be remotely closed/opened with the Bluetooth remote. To allow the door to close/open remotely, it's latch would also be replaced by a Bluetooth actuator that would close/open in sync with with the door opener to allow it to swing freely.

**SOLUTION SUBSYSTEMS:**

1. **Power Subsystem:**

- A lithium coin battery slot for the Bluetooth remote, allowing for batteries to be replaced.
- Converts standard outlet power to the motor and the PCB.
- A set of 4 AA batteries to power the door latch actuator.

2. **Processor Subsystem:**

- An ESP32 microprocessor for sending/receiving Bluetooth signals between the handle motor, the PCB, and the remote.
- Internal A/D conversion and signal processing.

3. **Door Close/Open Subsystem:**

- A 25 W to 30 W motor capable of producing 30 Nm of torque, allowing the closing/opening residential doors through jointed arm on a guided rail system.

4. **Door Latch Actuator Subsystem:**

- A 6 V DC solenoid actuator connected to a Bluetooth receiver and a PCB that opens in sync with the door being opened to allow it to swing freely.
- This system will be housed inside a custom 3D printed door handle

5.**Remote Control Subsystem:**

- A handheld Bluetooth remote with 3 buttons and a 8 segment hex display showing which door is currently being targeted for closing/opening.

**CRITERION FOR SUCCESS:**
- A minimum of two operational kits able to convert 80 inch tall, 36 inch wide, and 55 pound residential doors into automatic doors.
- A Bluetooth remote is able to switch between which door is targeting to close/open while displaying the set number of the currently targeted door and whether it is open or not.
- Each kit is cheaper and easier to install than commercially available kits with similar features.

Cypress Robot Kit

Featured Project

Cypress is looking to develop a robotic kit with the purpose of interesting the maker community in the PSOC and its potential. We will be developing a shield that will attach to a PSoC board that will interface to our motors and sensors. To make the shield, we will design our own PCB that will mount on the PSoC directly. The end product will be a remote controlled rover-like robot (through bluetooth) with sensors to achieve line following and obstacle avoidance.

The modules that we will implement:

- Motor Control: H-bridge and PWM control

- Bluetooth Control: Serial communication with PSoC BLE Module, and phone application

- Line Following System: IR sensors

- Obstacle Avoidance System: Ultrasonic sensor

Cypress wishes to use as many off-the-shelf products as possible in order to achieve a “kit-able” design for hobbyists. Building the robot will be a plug-and-play experience so that users can focus on exploring the capabilities of the PSoC.

Our robot will offer three modes which can be toggled through the app: a line following mode, an obstacle-avoiding mode, and a manual-control mode. In the manual-control mode, one will be able to control the motors with the app. In autonomous modes, the robot will be controlled based off of the input from the sensors.
