S.C.R.U.-F.E.: A Budget-Friendly, Ultra-Simple Robot for Young Makers and Programmers to Enjoy! Watch our beginner-friendly robotics project in action on YouTube here: https://youtu.be/-_pw6N5LGGA Help us keep the SCRU-FE resources flowing by sharing your projects, modifications, codes, and videos with our community of young programmers! We aim to make coding a breeze for elementary and middle school students without breaking the bank! This affordable robot project started when my 2-year-old daughter fell in love with her father's old ultrasonic robot from grade school days. The vintage bot is missing parts and won't work anymore, but she took good care of it since she was 1 year old! For her 3rd birthday, I set out to build a budget-friendly robot under $50 that we could make together. Every part costs less than $10, and most are easily found or open-source! The result is Scruffy, a fun-loving bot adored by my daughter. We made up the silly acronym S.C.R.U.-F.E., fitting his quirky appearance. Instructions for Your Own SCRU-FE Robot Materials: 1.
