Competition preparation

Robot Race Preparation: Testing Checklist

Q: What is different about preparing a line-following robot?

A line following robot also needs sensor calibration, line detection and autonomous steering tests for the actual line and surface conditions. The mechanical, power, documentation and rule checks still apply.

Prepare a race robot by checking the event rules, proving that it can stop reliably, and completing repeatable practice runs before chasing speed. This checklist is for a manually controlled wheeled robot. Line-following and autonomous races need additional sensor and software tests matched to their rules.

What you need

The current race rulebook and organiser instructions
Your assembled robot, controller and compatible power equipment
A clear practice area with a marked start, turns and finish
A stopwatch, a test log and the latest working code or configuration backup
Basic tools and compatible spare parts allowed by the event

1. Turn the rulebook into an inspection sheet

Write down the exact limits for your event: dimensions, weight, power, permitted controls, starting procedure and track boundaries. Record how penalties, restarts and timing work. Ask the organiser about anything ambiguous before modifying the robot.

Use the robot's actual measured configuration. A battery change, front attachment or spare wheel can affect compliance. Event rules take priority over a general preparation guide.

2. Check the robot before a timed run

Tighten mechanical fasteners and check that the wheels rotate without rubbing.
Secure the battery, controller and wiring; keep cables away from moving parts.
Check compatible battery and charger ratings and inspect connectors for damage.
With wheels raised, verify steering direction, throttle response and a reliable stop.
Test the loss-of-control stop behaviour before returning to floor practice.
Check that the driver can reach the controls comfortably without accidental inputs.

3. Establish a repeatable practice run

Begin at a low speed on a clear course. Practise starting, a straight section, a turn, a narrow section and stopping at the finish. Once the robot completes the route consistently, time several runs with the same setup.

A useful test log records the date, robot configuration, battery condition, speed setting, completion time and mistakes. Use the same start position and timing method. Compare both the completed times and the number of clean finishes; one fast run does not show that a setup is dependable.

3. Establish a repeatable practice run: reference table
Record	Example of what to write
Configuration	Wheel set, steering setting and code version
Run result	Completion time, boundary contacts and restarts
Observation	Overshot the second turn; driver corrected twice
Next change	Reduce turn sensitivity, then repeat the same course

4. Fix the cause of lost time

Review where a run loses time: wheel slip, wide turns, incorrect steering inputs, resets or interruptions. Make one adjustment and repeat the same test. Keep a backup of the last reliable configuration so you can return to it.

Increase speed only when the driver can steer and stop predictably. If the controller resets under acceleration, inspect power delivery and connections rather than immediately changing the driving code. Use the component specifications to investigate voltage and current requirements.

4. Fix the cause of lost time: reference table
Observation	Check or experiment
Wheels spin with little forward movement	Inspect tyre condition and the practice surface; reduce acceleration and compare.
Turns repeatedly overshoot	Reduce speed into the turn and adjust steering sensitivity one step at a time.
Robot resets when accelerating	Inspect the supply arrangement, connectors and motor-driver requirements.
Control behaves unpredictably	Stop floor practice and inspect the control link and failsafe behaviour.

5. Pack for inspection and recovery

Robotic Sir's DevFest Noida 2026 report includes a participant Robot Race. See that report for the event context, and the competitions section for published challenges. This preparation checklist does not replace the rulebook or establish eligibility for an event.

Pack the robot, controller, compatible charger and permitted batteries.
Bring the tools and spare connectors or fasteners needed for your own design.
Keep a local backup of the working code and a labelled wiring diagram.
Carry the registration or entry documents requested by the organiser.
Recheck rules and reporting instructions before travelling.
After transport, inspect the robot and perform a brief control and stop test in an authorised area.

Frequently asked questions

Practical answers to help you choose the next step.

Start by measuring consistent practice runs and identifying where time is lost. Improve steering, traction, reliability and driver control before increasing speed. Keep all changes within the current event rules and component ratings.

No. Size, weight, control methods, track layout, penalties and eligibility vary. Use the current rulebook and organiser instructions for the specific event.

A line-following robot also needs sensor calibration, line detection and autonomous steering tests for the actual line and surface conditions. The mechanical, power, documentation and rule checks still apply.
