If you want to flash or configure your AM32/BLHeli ESC using just an Arduino, here's a quick sketch that turns your Uno or Nano into a 1-Wire passthrough interface.


    Wiring:
    For Arduino Nano → connect the ESC signal wire to pin D3
    For Arduino Uno → connect the ESC signal wire to pin D11
    For Arduino Mega → connect the ESC signal wire to pin D51
    Ground always connects to GND

    How to use:
    Open the code below in Arduino IDE.
    Select your board (Uno or Nano) under Tools > Board.
    Upload the sketch — the correct pin is selected automatically based on your board choice.
    Wire your ESC signal wire to the pin mentioned above, and ground to ground.
    Connect to BLHeliSuite or AM32 configurator and flash your ESC.

    Code:
     #include <avr/io.h>
     //1-Wire Pin:

Introduction

Electronic Speed Controllers (ESCs), which have a direct impact on your bot's speed, acceleration, and maneuverability, are essential components of motor control in combat robotics and robowar sports. For your robot to operate at its peak efficiency, selecting the appropriate ESC firmware is essential.

To help you choose the best ESC firmware for your combat bot, we'll explain the differences between four common options in this guide: Simonk, BLHeli, AM32, and VESC.


1. SimonK: The Pioneer in Combat Robotics ESCs

Pros:
✅ The KKMulticopter flash tool makes programming simple
✅ Renowned for its quick throttle response
✅ Lightweight and straightforward firmware

Cons:
❌ Because it is incompatible with more recent ESC hardware, it is no longer widely accessible
❌ Does not have sophisticated features like active braking or telemetry

Overview:
One of the earliest popular ESC firmwares in the combat robotics community was Simonk firmware. Because of its quick response time and simplicity of programming, it was particularly well-liked in early drone and remote-control applications. Simonk-compatible ESCs became more difficult to locate as newer protocols like BLHeli and AM32 appeared, which resulted in a decrease in its use.

Best for:
• Legacy ESCs are still being used by older combat robots
• Simple control of a weapon or drive motor without intricate tuning


​2. BLHeli: The Successor to SimonK in Combat Robotics

Pros:
✅ More features than SimonK, such as PWM frequency tuning, active braking, and damped light mode
✅ After SimonK's demise, it became widely utilized in combat robotics.
✅ Very adaptable to various use cases

Cons:
❌ For combat robotics to operate at their best, manual tuning is necessary.
❌ The conflict between Russia and Ukraine halted development.
❌ It's possible that some ESCs won't get updates anymore.


Overview:
Following SimonK, BLHeli emerged as the preferred ESC firmware for combat robots. It provided enhanced response times, adjustable startup power, and braking modes, among other features. It is unclear whether future ESCs will continue to be fully compatible with BLHeli firmware, though, as official development and support have halted due to the ongoing conflict between Russia and Ukraine.

Best for:
• Combat robots that require a quicker throttle response than SimonK
• Builders who are prepared to adjust parameters for best results


​3. AM32: The New Budget-Friendly King for Combat Robotics

Pros:
✅ The best and most affordable choice for combat robots that are small and medium in weight
✅ Created by Alka Motors, this product is becoming more and more well-liked among crawler and combat robot enthusiasts.
✅ For robots that need immediate acceleration, this high initial torque at zero speed is crucial.
✅ Completely open-source and programmable

Cons:
❌ Not as extensively tested in high-speed combat robotics as BLHeli
❌ For best combat performance, some ESCs might need to be adjusted further.
 
Overview:
In the field of combat robotics, AM32 is the newest and most reasonably priced option, especially for small to medium-sized bots. It was created by Alka Motors and is ideal for drive motors in robot crawlers and wedge-style combat robots because it performs exceptionally well in low-speed, high-torque applications. AM32 is a highly recommended choice for novice builders because it is still being developed and supported, unlike SimonK and BLHeli.

Best for:
• Small to medium combat robots
• Crawler-style robots that require immediate torque
• Builders seeking an affordable programmable ESC


​4. VESC: The Most Powerful ESC for Advanced Combat Robots

Pros:
✅ Complete with features like telemetry, real-time data logging, and FOC (Field-Oriented Control)
✅ It can control both brushed and brushless motors, making it a universal ESC for weapons and drive systems
✅ Provides precise control and tuning for exceptional performance

Cons:
❌ More expensive than AM32, BLHeli, and SimonK
❌ This device requires manual parameter setup and is not plug-and-play
❌ More difficult to set up than other ESCs


Overview:
The most sophisticated and feature-rich ESC for combat robotics is VESC. With VESC, you can adjust every element of motor performance, including torque control, RPM limits, and regenerative braking, in contrast to other ESCs that concentrate on simple PWM control. It is not a plug-and-play solution, though; you have to manually set up the settings for every use case.

Despite its higher cost, VESC is the best choice if you're building a high-performance combat robot.

Best for:
• Highly precise advanced combat robots
• Systems of heavy weapons (such as flippers, hammers, and spinning drums)
• Builders who require the greatest amount of motor performance control


Which ESC is Right for Your Combat Robot?

 FeatureSimonK BLHeli AM32 VESC 
 Price Low Medium Low High 
 Ease of Use Easy MediumEasy Complex 
Features  BasicAdvanced High Torque  Full Control
 Support DiscontinuedStopped Active Active 
 Best for Basic BotsMid-tier Robots  Small Crawlers High-end Robots


​Which ESC is Right for Your Combat Robot?

• AM32 is a good choice if you want something simple and inexpensive
• BLHeli is still a good option if you need more features and don't mind tuning
• Select VESC if you want the most potent and adaptable ESC but be ready to invest some time in its setup


​Final Thoughts

Your budget, degree of experience, and performance requirements will all play a role in selecting the best ESC protocol for your combat robot.

ESC vs. VESC vs. ODESC: Simplified Guide for Choosing the Right Controller

When building a robot, drone, or electric vehicle, choosing the right motor controller is crucial. To help you choose the best option for your project, let's simplify ESC, VESC, and ODESC.

What is an ESC?

It represents Electronic Speed Controller. Its function is to regulates motor speed, direction, and braking (usually brushed or brushless) & its ideal for Simple robotics, RC cars, and drones. Its Reliable, small, and reasonably priced for simple uses. But the drawbacks are it has few features and customization options.


What is a VESC?

    It represents Vedder's Electronic Speed Controller. The purpose is to create an open-source, highly configurable motor controller. It's Ideal for High-performance uses such as robotics, electric skateboards, and customized electric cars.


  • Pros:
    • Fully programmable (using tools like VESC Tool).
    • Supports smooth acceleration, torque control, and braking.
    • Excellent for high-current loads and precise motor control.
  • Cons: Higher cost and steeper learning curve for beginners.


What is an ODESC?

ODESC stands for Open-Source Dual Electronic Speed Controller. It is developed for high-power applications requiring dual-motor control or more complex robotics & ideal for autonomous vehicles, combat robots, and devices that need synchronized motors.

  • Advantages:
    • Offers dual-motor support along with customization similar to VESC.
    • Frequently has improved durability and heat management.
  • Dis-advantages: Typically, bulkier and more expensive than standard ESCs.


Key Differences at a Glance

Feature  ESCVESC  ODESC
 Customization LimitedHigh Very high 
 ApplicationsSimple devices  High-performance Advanced robotics
Cost  Budget-friendly Moderate to high Higher-end
 Motor Types Brushed/Brushless Brushless (advanced) Dual Brushless/Brushed

Which One Should You Choose?

  • If you're building something basic, like a drone or RC car, go for an ESC.
  • For projects requiring high current, smooth control, or precision (like e-skateboards), choose a VESC.
  • If you are working on combat robots, dual-motor systems, or heavy-duty robotics, choose an ODESC.
