An advanced DIY robot platform featuring active shock-absorbing suspension and high-grip rubber tracks for all-terrain exploration. Ideal for Arduino, Raspberry Pi, and ESP32-based autonomous tank projects.

The Tank Robot Chassis Kit with Shock Absorbing Suspension is engineered to bridge the gap between indoor toys and rugged exploration platforms. Featuring an 8-channel plastic tension spring system, this crawler ensures that your sensors and electronics remain stable even when the terrain is not. This Probots™ Lab Verified  suspension setup allows each wheel to move independently, maintaining maximum track contact and grip on uneven surfaces, which is critical for autonomous navigation and mapping projects.

Industrial Build Quality and Reliable Locomotion Durability is at the core of this chassis, which is constructed from high-strength reinforced plastic mounts to withstand the rigors of heavy-duty DIY projects. The dual high-torque DC motors are pre-installed in a precision gearbox, providing the necessary "heavy-lifting" power for payloads up to 1kg. To ensure long-term reliability for your controllers, we have designated this kit as Probots™ Logic-Safe . This means the motor specifications are verified for compatibility with standard 3.3V and 5V logic drivers (like the L298N or TB6612FNG), preventing back-EMF spikes from damaging your sensitive ESP32 or Raspberry Pi boards during high-load maneuvers.

Seamless Integration and Instant Project Deployment We understand that time spent troubleshooting hardware is time taken away from coding. That’s why this kit supports Probots™ Instant-R&D , featuring a top plate with pre-drilled M3 and M4 mounting holes specifically spaced for the industry-standard Arduino Uno, Raspberry Pi 4/5, and Jetson Nano. The integrated battery holder (supporting 9V or AA configurations) is strategically positioned to maintain a low center of gravity, significantly reducing the risk of tipping during steep 30° climbs. Whether you are building a surveillance bot with an ESP32-CAM or an AI-driven obstacle avoider, the hardware is ready to work right out of the box.

Strategic Project Evolution and Future-Proofing This chassis isn't just a frame; it’s an invitation to grow your engineering skills. In our  Unlock New Capabilities (Project Evolution) framework, this kit is the perfect upgrade for makers who have outgrown 2WD acrylic kits. It introduces the complex mechanics of differential drive and track tensioning without the prohibitive cost of industrial-grade metal tanks. By mastering this platform, you gain the skills needed for advanced robotics, such as dead-reckoning with encoders or FPV (First Person View) outdoor exploration. It is a robust, versatile foundation that ensures your project won't just move—it will conquer.

Specifications:

  • Dimensions: 185mm (L) x 97mm (W) x 50mm (H)
  • Suspension System: 8-way active spring-loaded independent damping
  • Locomotion: Dual high-torque DC Motors (Integrated Gearbox)
  • Track Type: High-grip interlocking engineering plastic tracks
  • Chassis Material:  Plastic 
  • Power Compatibility: Integrated 2x AA or 1x 9V Battery Holder 
  • Mounting Holes: Pre-drilled for Arduino Uno, Raspberry Pi, and Ultrasonic Sensors
  • Climbing Ability: Up to 30° incline (Terrain dependent)

Key Applications & Projects

  • Autonomous Exploration: Build a rover that navigates gardens or rocky paths using GPS and Lidar.
  • Surveillance Bot: Mount an ESP32-CAM or Raspberry Pi Camera for a low-profile, "stealth" indoor monitoring tank.
  • Rescue Robotics: Prototype a mini search-and-rescue vehicle capable of traversing debris.
  • AI Vision Tank: Use a Jetson Nano to perform object tracking while the suspension handles the bumps.

Project Evolution 

  • The Starting Point: If you have already mastered basic line-following on a 2WD acrylic car, this is your next logical step.
  • The Feature Upgrade: Moving to this chassis unlocks all-terrain mobility. You are no longer restricted to tiles; you can now experiment with grass, gravel, and small obstacles.
    Effort Level: Intermediate.
  • Requirements: You will need a dual-channel motor driver and a microcontroller to begin.

Virtual Technician & Wiring

  • Safety Warning: Always ensure your motor driver can handle the 9V input. Do not connect motors directly to microcontroller pins.

Basic Pin Mapping:

  • Motor L (+/-): Connect to Driver Out 1/2
  • Motor R (+/-): Connect to Driver Out 3/4
  • Battery Holder: Connect to Driver VCC and GND (Ensure common ground with MCU).

1 X Tank Robot Chassis Kit with Motors & Battery Holder - Shock Absorbing Suspension DIY Crawler

Frequently Asked Questions (FAQ)

  1. Does the kit come pre-assembled?
    No, it is a DIY kit designed to teach mechanical assembly and robotics fundamentals.
  2. What is the recommended operating voltage for the motors?
    The motors perform optimally between 6V and 9V DC.
  3. Can I use a Raspberry Pi 4 to control this?
    Yes, there is ample space on the top plate. Use a buck converter to provide 5V to the Pi.
  4. Are the tracks made of rubber or plastic?
    They are made of high-strength engineering plastic segments for durability and low friction.
  5. How does it turn?
    It uses "Differential Steering" (skid-steer). To turn left, stop the left motor and run the right motor forward.
  6. Can it climb regular stairs? No, it is designed for obstacles up to 2-3cm and inclines up to 30 degrees.
  7. What motor driver is best for this?
    The L298N or the TB6612FNG are excellent choices.
  8. Does it include an Arduino board?
    No, this is the mechanical chassis and motor kit only.
  9. How much weight can the chassis carry?
    It is designed for a payload of 500g to 1kg for optimal suspension performance.
  10. Is the suspension adjustable?
    The springs are fixed-rate, but you can adjust track tension by removing or adding track links.
  11. Are the motors noisy?
    They are standard geared DC motors; the tracks produce a characteristic "mechanical" sound during movement.
  12. What is the shaft diameter of the motors?
    The gearbox output is a standard 4mm D-type shaft.
  13. Can I add encoders to these motors?
    The stock motors do not include encoders, but there is space to mount external optical encoders on the wheel axles.
  14. Is the chassis waterproof?
    No. The motors and battery compartment are exposed. Avoid wet conditions.
  15. What size battery fits in the holder?
    The included holder fits 2x AA batteries or a 9V snap;
  16. Are the tracks replaceable if they break?
    The tracks are highly durable, but individual links can be swapped if needed.
  17. What is the ground clearance?
    Approximately 12mm-15mm depending on the payload weight.
  18. Can I mount a robotic arm on it?
    Yes, a lightweight acrylic or 3D-printed arm can be mounted on the top plate.
  19. What tools are required for assembly?
    A standard Phillips head screwdriver and a small wrench (included in most batches).
  20. Why are the tracks slipping?
    Ensure the tracks are properly tensioned. If they are too loose, they may jump off the drive sprocket during high-speed turns.
