Skipping Rope Counting

2023 Spring CS565 Mini-Proejct

By Nayoung Oh and Jinseo Lee

Prepare hardware

What you need to prepare

• Arduino Nano 33 BLE Sense
• Arduino Nano shiled
• 4 X AAA battery with a battery shiled
• One jump rope
• One 3D printing of the modeling/jump_rope_handle.stl
• One laser cutting of 3mm MDF of modeling/lower_plate.dwg and modeling/upper_plate.dwg
• Some supporters, bolts, and nuts (recommend to use nylon nut for connecting the rope handle)

Assemble the new handle and Arduino

Collect training data

You should upload data_collection/data_collection.ino into the board. This program will collect imu sensor data.

Then, using the data_collection/data.py to communicate with the arduino and save the data about 15 seconds.

Training your own model

Use the Jump_Classifier_Training.ipynb to train the model and convert into Arduino compatible format.

Check the performance using K-Fold

Use the Jump_Classifier_KFold.ipynb to check the performance of the model using K-Fold

Test in the real-world setting

Download the apk file final_jump.apk into your smartphone. Currently, only Android is supported.

Upload final_program into your Arduino.

And enjoy!
