Hyperdolly: Kickstarter Version vs. HY‑01 — Full List of Upgrades

Although the overall design of the HY-01 remains familiar to the original Hyperdolly presented on Kickstarter in late 2023, it has been substantially re-engineered internally. Below is a complete list of improvements introduced since the Kickstarter batch.

Hardware

Core Electronics

• Arduino platform replaced with ESP32 (modern, pre-certified wireless module)
  The new architecture delivers significantly faster interface response, lower control latency, improved power efficiency, and a fully FCC-compliant wireless foundation — essential for proper global scalability.

Remote Control

• Power source redesigned (2×14500 3.7V → 3×AA 1.5V)
  Standard AA batteries are globally available and easier to replace on set.
  
• USB power input added (5V / 2A)
  The remote can now run directly from a power bank or external supply, allowing extended runtime and battery hot-swapping without interruption.
  
• Redesigned strap hook mount
  More accessible geometry.
  

Motion & Mechanics

• New soft wheels
  Made of 45A Shore hardness polyurethane, the tires provide an optimal balance between motion stability and performance on imperfect floors.
  
• Worm gear backlash adjustment added
  Fine steering calibration is now possible, resulting in more predictable curved motion paths.
  
• Rear wheel alignment refinement
  The unfolded end-position is factory-preset and adjustable, ensuring improved straight-line tracking and trajectory consistency.
• Reinforced motor unit-to-frame bracket
  The structural bracket connecting the motor unit to the main frame has been redesigned for increased rigidity and durability
• Bigger steering angle adjustment knob
  Allows for more comfortable and accurate fine-tuning.
  

Mounting & Transport

• Rubber hook mounts added
  A new mounting option designed for heavy-duty tripods and increased grip stability.
  
• Case interior redesigned
  Improved compartment layout with more secure remote storage.
  

Firmware

• Stepper motor motion engine upgraded
  Smoother acceleration and deceleration curves with 1.3× higher maximum speed.
  
• Battery charge indicator added (dolly unit)
  
• Signal strength indicator added
  
• Sleep timer implemented
  
• Improved Hyperlapse mode with more stable interval behavior.
  
• Multiple bug fixes and overall system stability improvements
