14 Interactive Climbing Holds

The primary goal of this project is to introduce interactive climbing holds to improve end-user experience for climbers and climbing gyms.

Climbing gyms normally have set "routes", which is a way of increasing the difficulty and complexity when climbing a wall. These routes only allow certain rocks to be used when climbing the wall, and these rocks are normally denoted by their color or some attached colored tape. One of the main problems in climbing gyms is that there is a high density of holds which often vary in color/ have multiple colored tapes on each one, making it difficult to determine all the valid rocks in the current route being attempted. Furthermore, climbing gyms often replace old routes with new routes every once in a while, which may be frustrating to some climbers that are still trying to finish past routes. Gyms also don't interact with every climber; thus, new routes may not cater to the core audience of the gym.

Base Goals:
Our project goals are two-fold. Firstly, we want to allow climbers to easily identify and select from available routes through a web interface, which will light up the relevant route and time the user as they traverse the route. Secondly, the data from climbing times and climber ids can help the climbing gym identify popular routes, analyze data to create routes that most closely match climber needs, and set routes conveniently by scanning rocks.

Reach Goals:
Create an interface for non-gym staff to set routes
Create an interface for rating routes based on difficulty and user feedback
Creating analytics for routes for feedback to the climbing gym

Technical Description:
Each rock will contain a microcontroller, some communication module (wifi?), RGB LED, a battery, and some low-power RFID reciever.
The rocks are interfaced through a small passive RFID chip attached to a low profile wristband worn by the climber. The primary purpose of the wristband is to identify the climber and communicate with the server about the climber's progress throughout the route.
A server that will be able to communicate to all the rocks and will host the web application that the climbers and gym will interface through to control the array of rocks on the wall.

Example Application:
1. Climber receives wristband and browses available routes to climb, filtered by difficulty.
2. After choosing a non occupied route, the route lights up according to specified color.
3. Upon reaching the starting position (wristband in contact with designated starting hold), the timer begins.
4. Upon finishing the route (wristband in contact with designated end hold), the climber's total time is stored in the server and a leaderboard is updated to show best times.
5. Data collected from climbers is used by the gym owners to determine the difficulty, frequency, and style of new routes.

Filtered Back – Projection Optical Demonstration

Featured Project

Project Description

Computed Tomography, often referred to as CT or CAT scans, is a modern technology used for medical imaging. While many people know of this technology, not many people understand how it works. The concepts behind CT scans are theoretical and often hard to visualize. Professor Carney has indicated that a small-scale device for demonstrational purposes will help students gain a more concrete understanding of the technical components behind this device. Using light rather than x-rays, we will design and build a simplified CT device for use as an educational tool.

Design Methodology

We will build a device with three components: a light source, a screen, and a stand to hold the object. After placing an object on the stand and starting the scan, the device will record three projections by rotating either the camera and screen or object. Using the three projections in tandem with an algorithm developed with a graduate student, our device will create a 3D reconstruction of the object.


• Motors to rotate camera and screen or object

• Grid of photo sensors built into screen

• Light source

• Power source for each of these components

• Control system for timing between movement, light on, and sensor readings
