What kids learn
About Robo Engineer
Robo Engineer is where kids stop following instructions and start thinking like engineers. Every week focuses on a specific transmission concept — spur, bevel, worm, rack-and-pinion — so by term's end students can look at a real-world machine and reason about how it works.
By the end of a term, students can:
- Identify and correctly use spur, bevel, worm and rack-and-pinion gears
- Reason about torque, speed reduction and mechanical advantage
- Debug a build when something doesn't turn or move
- Explain a real-world machine (crane, escalator, mixer) in engineering terms
8-week term
The curriculum journey
A concept-driven progression — every week unlocks a new STEM idea, with the exact builds refreshed each term.
Week 2
Bevel & angle drives
Turn horizontal rotation into steering. 90° axis change.

Week 5
Worm gears & lifting
Slow, high-torque motion for lifting loads.
Example builds
Dump Truck
Mobile Crane
Self-locking drivesCable spooling
Week 6

16 featured models
A cross-section of the 60+ full curriculum — with the exact mechanism each build teaches.
Trike Motorcycle
The drive is made on a bevel gear. The steering wheel can be turned, ride straight, backward or in a circle.
Airplane
The rotation of the propeller is realized with the help of a multi-link system of mechanical transmissions.
Army Jeep
The model uses a bevel gear to set the truck in motion.
Bat Mobile
An increasing cylindrical gear is used.
Carousel
The drive uses a bevel gear that converts rotation from horizontal to vertical.
Dump Truck
Drive is made on a worm gear. The raising and lowering of the body is controlled by a smart motor.
Elevator
The movement of the cabin occurs due to the winding of the cable on a reel mounted on the driven shaft of the worm gear.
F1 Race Car
The drive is made on a spur gear.
Forklift
A combination of worm and rack-and-pinion gears is used.
Sliding Doors
A combination of belt and bevel mechanical gears operates the sliding doors.
Helicopter
A crown gear rotates the main and auxiliary propellers of the helicopter.
Mixer
The rotation drive of the mixer rims is made on a bevel gear — transforming rotation from horizontal to vertical.
Mobile Crane
The crane boom is lowered and raised by a worm gear drive.
Power Plant
Gear reducing speed transmission — a smaller drive gear turns a larger driven gear.
Steering Race Car
The servo motor controls the steering mechanism, able to rotate through a 90° angle.
Windmill
A combination of belt and bevel gears ensures synchronous rotation of both the mill blades and the mill wheel.
