Beginner’s guide · Make & build
Build the drive bot first,
and let the arena contain the weapon.
A rule-compliant antweight push bot teaches weight, radio failsafe, chassis, motors and driving before any active weapon is considered.
Quick answer
Complete one drive-only antweight before expanding the setup
Choose a real UK event before choosing parts and read its latest weight, size, battery, radio, shutdown and failsafe rules. Build a simple two-wheel drive-only wedge with a visible approved power switch or link, account for every gram in a spreadsheet, protect wheels and wiring, prove that drive stops when the transmitter is switched off and practise pushing cardboard blocks only in a low-energy test box before submitting the robot for the organiser’s tech check.
- 01
The event rules define the robot; television formats and another country’s weight names are not interchangeable. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
- 02
A drive-only machine teaches packaging, traction, radio setup, repair and driving without an active weapon system. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
- 03
Weight must be reserved for fasteners, wire, connectors, labels and protective structure, not just headline components. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
- 04
A combat robot is activated only under organiser procedure and operates only inside a suitable closed arena. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
What to expect
What robot combat is really like at the start
The useful beginner controls are preparation, one bounded task and a record of the result; specialist equipment matters only when it solves a repeated limitation.
Weight
A few connectors and thicker armour can erase the entire allowance on a 150 g antweight. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
Drive
Traction, gearing and weight distribution usually matter more at first than maximum motor speed. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
Radio
A robot that continues moving after signal loss fails a basic safety boundary. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
Event
Tech inspection, locking devices and activation order are part of the build, not paperwork after it. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
Core method
The core robot combat method
Choose the ruleset and event
Download the current organiser rules and write every hard limit and required safety feature into the design brief. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
Prototype the drive train
Test motors, controller, receiver and battery at low energy before designing tight armour around them. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
Package and weigh continuously
Maintain a live weight budget and provide strain relief, isolation and tool-free safe shutdown. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
Prove safe behaviour
Test failsafe with wheels clear, then practise controlled driving and recovery with no active weapon fitted. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
Useful products
Products with a clear job in the route
The RC tool kit supports chassis assembly, the meter helps verify low-voltage wiring and the safety glasses provide baseline eye protection; competition-specific drive kits should be chosen from the organiser’s current guide.
Tamiya RC Tool Kit, 8 Piece
A simple drive-only robot needs reliable assembly more than specialist weapon tooling.
AstroAI TRMS 6000-Count Digital Multimeter
It turns wiring and power faults into separate testable questions.
3M SecureFit 200 Safety Glasses
They are easy to keep at the bench for routine impact risks.
First project
Build and tech-check one drive-only antweight
Aim for reliable movement, instant failsafe and repairable packaging rather than damage.
- 01
Select an event and rules
Record the exact class, size, weight, battery, radio and shutdown requirements. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
- 02
Bench-test the electronics
With wheels clear, verify direction, endpoint, signal loss and a safe power-off route. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
- 03
Build a simple wedge chassis
Protect wiring and wheels, avoid sharp exposed edges and keep access to the shutdown control. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
- 04
Weigh the complete robot
Include battery, fasteners, link, labels and every removable panel and retain a margin. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
- 05
Practise and attend tech check
Drive only in a safe enclosure, bring the required lock or restraint and follow the organiser’s activation sequence. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
What can wait
What can wait until the first result
Delay anything that adds cost, risk or another variable before the basic workflow has produced something you can review.
- 01
Spinning weapons
Stored rotational energy and fragment risk require mature design, a rated arena and organiser approval. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
- 02
Large weight classes
Battery energy, machine tools, cost and destructive force rise quickly. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
- 03
Exotic drive systems
A reliable two-wheel robot reveals the event workflow with fewer failure modes. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.
- 04
Garage combat
Protective eyewear is not a substitute for an engineered fully enclosed arena. Record what happened during robot combat so the next attempt changes one known variable instead of several guesses.

Weapons stay disabled outside a rated arena
The safe operating system includes the organiser, enclosure, shutdown control, locking device and handling procedure.
- Build to the chosen event’s current written rules and accept the organiser’s decision at inspection and activation.
- Keep active weapons mechanically locked and power isolated outside the arena; a transmitter switch alone is not isolation.
- Test failsafe with the robot restrained and wheels clear and stop all motion when the control link is lost.
- Use only compatible undamaged batteries, chargers and connectors and control charging, transport and storage fire risk.
- Never test a weapon in an open room, garden or improvised box and keep spectators outside the arena boundary.
Outside help
When outside help earns its place
A live robot-combat club or event is essential because the arena, tech inspection and activation discipline cannot be reproduced by a video.
Choose the weight class and organiser first and ask whether drive-only rookies, loan equipment and supervised bench testing are supported.
Use outside help after the first robot combat attempt can reveal the exact technique, access or safety problem that needs live correction.
