Mechanism Enhances Tendon's Pulling Capacity
A ratchet device commonly found in garages can be invaluable for tightening tough-to-reach bolts in everyday home projects. However, a unique ratcheting actuator was developed by Chronova Engineering for an unconventional application: assisting in the pulling of tendons.
This cutting-edge machining project required the creation of a mechanism designed to pull and release tendon fibers. Precision was crucial for bio-mechanics research, as the tendons needed to be pulled and released to accurately measure the movement of the fingers or toes. The distance pulled by the actuator would then be compared with the actual movement.
The use of this actuator in biomechanical or robotic systems could potentially help improve the treatment of people with impairments, although in the present case, the "patient" being studied is a chicken's foot. The manufacturing process involved multiple watch lathe operations and pantographed patterns.
A combination of custom and commercial screws was used alongside a peg gear, cams, and a high-performance servo to create the complex ratchet mechanism. The system could be easily controlled using an Arduino, allowing it to perform its function effectively.
The ratcheting actuator, despite its unusual application, showcases exceptional machining capabilities. As a result, it remains an intriguing piece of machinery with far-reaching potential.

- Incorporating an Arduino for control, the ratcheting actuator, with its complex mechanism combining commercial and custom screws, peg gear, cams, and a high-performance servo, can be considered a fascinating example of technology integration, even among other gadgets.
- One could argue that the unconventional application of the ratcheting actuator, rather than being limited to home improvement tasks like tightening Arduino-controlled gadgets, holds significant potential for biomechanical and robotic systems, thus broadening its horizons in the realm of technology.
