JCB JS220 Excavator ------------------------------------ This is the famous JCB JS220 Excavator model as designed by the inimatable Jennifer Clark ( http://www.jenniferclarkbass.com/lego/). It was a tremendous amount of work getting all of the pneumatic hoses modeled, but the results are worth it. Jennifer has already posted a very thorough explanation of the functions and design of this model, so I will not attempt to repeat them here. I'll just list a few statistics: - 3 motors in model (left/right drive, slew), 2 motors in controller (compressor) - 8 pneumatic cylinders ~ 50 feet of pneumatic tubing (including umbilical) - 1708 total parts, 296 tread links A brief synopsis of the renders: - js220-1.jpg: This was rendered while I was still working on the construction of the MPD. It shows my progress on the arm. Default light sources. - js220-2.jpg: Same as above but after more progress on the model. - js220-3.jpg: Completed model with radiosity and HDR lighting. - js220-4.jpg: Nearly same as above but with greater perspective and slight focal blur. - js220-5.jpg: Final. Reflective floor, radiosity level 5, recursive anti-alias, white sky sphere, overhead area light. - js220-6.jpg: Simple render. I just posted this as it is the only image which also shows the controller/compressor. - Blakbird 2009
