# Problem
In disaster and rescue scenarios (collapsed structures, smoke-filled buildings, unstable debris fields), responders often need quick situational awareness without putting people at additional risk. Small ground robots can provide remote surveillance, but many are controlled using joysticks or complex interfaces that require training and constant fine-grained input. In high-stress environments, precise manual control becomes a liability as it increases cognitive load, slows down deployment, and makes it harder for responders to focus on interpreting the scene and coordinating rescue actions. The result is that existing teleoperated robots can be underutilized or difficult to operate effectively when time and attention are limited.

# Solution
We will build a rescue surveillance robot with an intuitive gesture-based control interface that translates simple hand motions into high-level movement commands, paired with onboard safety behaviors to reduce operator burden. The operator wears a gesture device (IMU-based glove or wrist module) that detects orientation/motion and wirelessly transmits commands such as move forward, turn, stop, rotate/scan, and return. The robot executes these commands while enforcing safety constraints (slowing/stopping near obstacles), and provides real-time situational awareness through video streaming and sensor feedback. This enables faster, more natural control than a traditional remote controller, allowing responders to deploy the robot quickly and maintain attention on the environment rather than micromanaging the robot’s motion.

# Solution Components

## Subsystem 1
We want to make a glove that would recognize the different gestures made and transmit the corresponding motion to the robot. The motions we want the glove to recognize are forward/backward, turn left/right, and stop. Additional features, if we have time, would include “come back” and “spin/dance”.

Base System - Custom PCB
1. IMU
2. Bluetooth Transmitter/Receiver
3. 3-4 Flex sensors (1 for each finger)
4. 1 MCU (think Raspberry Pi chip)
5. Buttons to control the mode and turn on
6. Battery (PSU)

Additional System:
1. 1 Haptic Feedback Module

With the base system, the purpose of the IMU would be to detect pitch and roll because these motions would correspond with directions. Then the flex sensors would be used to detect stop and come back. We would have an MCU on the glove that will detect the different movements and send commands to the robot.

For the bonus features, we would like to have a receiver that recognizes it for our bonus feature of obstacle avoidance. When the robot has detected an obstacle and has stopped, it lets the user know through haptic feedback that it cannot move in that direction. Another bonus feature would have the glove be in different modes where it can control either the camera move (spin to see different areas).

## Subsystem 2
We want to build a system on the robot. The robot will be receiving the commands from the glove and then moving in the corresponding direction. Here are the components that will be required:

Base System - not PCB
1. Bluetooth Transmitter/Receiver
2. Motors
3. Caterpillar Track (For multi-terrain compatibility)
4. Raspberry Pi Board

Additional System
1. Camera for surveillance
2. TOF(Lidar) sensors
3. Heat/Night vision camera? (Better at looking through debris?)(Maybe too expensive?)

The robot base system will accept commands from the glove and then move accordingly. We have a caterpillar track for multi-train capability. We will use a Raspberry Pi board for receiving and executing the commands. The purpose of the board is so that we can easily add other modules for the additional system features.

The additional system will include a camera that will transmit the camera data to an external laptop. Then we will have Lidar sensors for obstacle avoidance so that if you give an instruction to the robot but it will hit an obstacle to do the command it will stop and transmit that back to the arm.

# Criterion For Success

The project will be considered successful if the following functional and performance objectives are met:

## 1. Reliable Gesture Recognition (Glove Subsystem)

The glove must accurately detect user gestures using IMU orientation (pitch and roll) and finger flex sensor inputs. The system must correctly classify and generate control commands corresponding to:

- Move forward
- Move backward
- Turn left
- Turn right
- Stop

## 2. Wireless Communication
The glove subsystem must transmit gesture commands to the robot wirelessly using Bluetooth (BLE).

## 3. Robot Motion Execution
The robot subsystem must correctly interpret received commands and translate them into motion, reliably performing:
- Forward and backward motion
- Left and right turns
- A 360° surveillance spin

## Stretch Goals (Advanced Success Criteria)
### 1. Safety Through Obstacle Avoidance
The robot must integrate onboard distance sensing (ToF/LiDAR) to prevent unsafe movements. The robot must stop before impact. The system must override unsafe commands in real time.


### 2. Haptic Feedback to User (Closed-Loop System)
When the robot is unable to execute a command due to an obstacle, haptic feedback must be sent to the glove to notify the user.
### 3. Camera/visual feedback
We will add a camera or thermal/infrared sensing method to detect human presence in low-visibility environments and provide easy remote control.

Recovery-Monitoring Knee Brace

Featured Project

Problem:

Thanks to modern technology, it is easy to encounter a wide variety of wearable fitness devices such as Fitbit and Apple Watch in the market. Such devices are designed for average consumers who wish to track their lifestyle by counting steps or measuring heartbeats. However, it is rare to find a product for the actual patients who require both the real-time monitoring of a wearable device and the hard protection of a brace.

Personally, one of our teammates ruptured his front knee ACL and received reconstruction surgery a few years ago. After ACL surgery, it is common to wear a knee brace for about two to three months for protection from outside impacts, fast recovery, and restriction of movement. For a patient who is situated in rehabilitation after surgery, knee protection is an imperative recovery stage, but is often overlooked. One cannot deny that such a brace is also cumbersome to put on in the first place.

--------

Solution:

Our group aims to make a wearable device for people who require a knee brace by adding a health monitoring system onto an existing knee brace. The fundamental purpose is to protect the knee, but by adding a monitoring system we want to provide data and a platform for both doctor and patients so they can easily check the current status/progress of the injury.

---------

Audience:

1) Average person with leg problems

2) Athletes with leg injuries

3) Elderly people with discomforts

-----------

Equipment:

Temperature sensors : perhaps in the form of electrodes, they will be used to measure the temperature of the swelling of the knee, which will indicate if recovery is going smoothly.

Pressure sensors : they will be calibrated such that a certain threshold of force must be applied by the brace to the leg. A snug fit is required for the brace to fulfill its job.

EMG circuit : we plan on constructing an EMG circuit based on op-amps, resistors, and capacitors. This will be the circuit that is intended for doctors, as it will detect muscle movement.

Development board: our main board will transmit the data from each of the sensors to a mobile interface via. Bluetooth. The user will be notified when the pressure sensors are not tight enough. For our purposes, the battery on the development will suffice, and we will not need additional dry cells.

The data will be transmitted to a mobile system, where it would also remind the user to wear the brace if taken off. To make sure the brace has a secure enough fit, pressure sensors will be calibrated to determine accordingly. We want to emphasize the hardware circuits that will be supplemented onto the leg brace.

We want to emphasize on the hardware circuit portion this brace contains. We have tested the temperature and pressure resistors on a breadboard by soldering them to resistors, and confirmed they work as intended by checking with a multimeter.
