High degree of challenges as there are so many limitation factors on system and complex mechanical design. , need to replicate the Steampunk style in movie design with old school cable operation steam excavators exteriorly.
the cable operation, mechanically in the movie is only done by 3d CGI animation, not only impossible to replicate it all in reality, it also can't be accurately controllable in a scale down size , we want to achieve that the both arms not only fully functional on performance, also powerful enough can distort something like in the movies. So it needs to build very firmly mostly by stainless steel. So each arm weight around 100kg
flexible enough to perform all the movement replicate from movie design (total 14 moving articulation and nearly 10 more visual moving parts, event the old school cable operation has been visually replicated, not installed yet when the video is shot), simple enough to detachable for safety transportation to a different city. And easy to re-assembled too. client request additional sound effects coordinate with has risen top platform replicate one key movie scene, and smoking steaming efforts. In an already crowded internal space.
as the robot vehicle need to ship to different city later and being constructed in different factory, 2 arm need to be easily detachable. The wires and control system must be simple and detachable too. Use too many stepper motors would be a nightmare and unreliable to maintaining too. so the arm articulation still uses cylinder power, but needs to hides leverage inside the arm, which without a triangular layout, it was inefficacious and very complex to design mechanically.
challenges are continuing struggle balance between following contradicting design and engineering requirements:
small enough to hide inside the arm, but also powerful enough to waving 100kg arm with extra power to distort things.
Two robot arm builds by computer precision cutting stainless steel and aluminium, not only reconstructs the actual mechanical function accordance with excavators in reality, the details also decorated to reproduce the Steampunk style in movie design. with old school cable operation steam excavators exteriorly. so can not use exposed modern Hydraulic System Boom Cylinder. Which is most efficacious leverage system.
Very carefully elaborate thousand pieces of parts in the design and construction process, that can work together under complete integrated operation of compact complex mechanical equipment.
