Design Your Antweight Vertical Spinner in Fusion

by Mona
Go from your first Fusion sketch to a fully designed 1 lb combat robot with a real metal vertical spinner. You'll pick verified parts, learn the physics of spinning weapons, design a printed chassis around a bearing-supported weapon, and follow real event safety rules to commission it.

Lesson 1
The 454-Gram Puzzle: Why Every Gram Counts image

The 454-Gram Puzzle: Why Every Gram Counts

A 1-pound robot can pack enough energy to flip an opponent into the air. How do you divide 454 grams among metal, motors, and armor?

Lesson 2
Power, Push, and Protection: Picking Real Combat Hardware image

Power, Push, and Protection: Picking Real Combat Hardware

Motors, speed controllers, and batteries carry cryptic specs like 2205, 2300KV, and 45C. How do you match them so nothing burns out or blows your weight limit?

Lesson 3
Blue Lines Lie: The Sketch That Holds Its Shape image

Blue Lines Lie: The Sketch That Holds Its Shape

Your first CAD sketch looks straight until you pull one corner and the whole part warps. What tells Fusion how your drawing is allowed to move?

Lesson 4
From Flat to Solid: Features, Fillets, and the Timeline image

From Flat to Solid: Features, Fillets, and the Timeline

A flat profile becomes a solid plate with one command. How does Fusion track every change so you can redesign parts without starting over?

Lesson 5
Caliper to CAD: Modeling Real Hardware Stand-Ins image

Caliper to CAD: Modeling Real Hardware Stand-Ins

A motor that is off by half a millimeter will not bolt into your printed chassis. Which dimensions must be exact, and which can you simplify?

Lesson 6
The Unibody Chassis: Pockets, Clearances, and Impact Paths image

The Unibody Chassis: Pockets, Clearances, and Impact Paths

Your components need a snug home that can take an arena hit. How do you carve internal pockets while keeping the frame stiff and light?
Start
Lesson 7
The Tooth and the Rim: Shaping a Metal Spinner Disc image

The Tooth and the Rim: Shaping a Metal Spinner Disc

A spinning disc stores energy in its mass and spin rate. How do you shape the profile and teeth so it bites deep instead of bouncing off?
Start
Lesson 8
Shafts, Spacers, and Bearings: The Spinning Weapon Stack image

Shafts, Spacers, and Bearings: The Spinning Weapon Stack

Your disc spins at thousands of RPM and hits hard. How do bearings, spacers, and a dead shaft keep it spinning without ripping off the chassis?
Start
Lesson 9
Traction and Torque: Hubs, Wheels, and Differential Drive image

Traction and Torque: Hubs, Wheels, and Differential Drive

Two motors, two wheels, and no steering rack. How do wheel diameter, tire grip, and shaft connections decide whether you control the arena or spin out?
Start
Lesson 10
Lids, Fasteners, and Access: Sealing a Bot That Must Open image

Lids, Fasteners, and Access: Sealing a Bot That Must Open

Combat robots take severe shock loads and must open quickly between rounds. How do screws and threaded inserts hold plates tight without stripping plastic?
Start

Make It Real

Lesson 11
Filaments Under Fire: Designing for the 3D Printer image

Filaments Under Fire: Designing for the 3D Printer

The same 3D model can crack on the first tap or bounce off a steel wall. How do print orientation, perimeter passes, and filament chemistry decide?
Start
Lesson 12
Commissioning the Machine: Failsafes, Slicing, and Enclosed Testing image

Commissioning the Machine: Failsafes, Slicing, and Enclosed Testing

From final G-code to first spin-up. What systematic safety checks, radio failsafes, and containment barriers must happen before your weapon ever powers on?
