Summer Workshop Agenda & Curriculum 2025
Build & Compete 3D Printed Rock Crawler
5-Day Workshop | Ages 12+ | Morning Session (9:30 AM - 12:00 PM)
Participants will construct a 3D printed RC rock crawler, understanding its unique mechanics for off-road performance, and test it on a unique rock crawling course located at the historic ENCI Maastricht.
Overall Goal
To guide participants through the assembly of a 1/24 scale 3D printed RC rock crawler, focusing on the principles of suspension articulation, weight distribution, and high-torque drivetrains necessary for navigating challenging terrain.
Skills Used/Developed
- Detailed mechanical assembly (multi-link suspension, portal axles if applicable)
- Understanding of crawler-specific electronics (high-torque motors, specialized ESCs)
- Problem-solving for complex assemblies
- Fine motor skills
- Understanding of vehicle dynamics: center of gravity, articulation, approach/departure angles
- Strategic thinking for navigating obstacle courses
Tools Used
- Screwdriver set (various sizes, Phillips & hex)
- Pliers (needle-nose)
- 3D printed crawler parts kit (chassis, links, axle housings, etc.)
- RC electronics (high-torque motor, crawler ESC, steering servo, battery, charger)
- RC Transmitter & Receiver
- Weights for tuning (optional, provided)
- Safety glasses
