Step 10: Getting frames to fit... Once all of the frames were built, it was time to get the two main frames sliding together, so the linear rails (drawer slides) and the pneumatics started going together.
In the video you can see how hard it is to control the air, I am using a standard blow nozzle and just shooting air into the input to make sure the frames will move and not be locked together. In the final version, I fixed the flow by adding in a flow restrictor on the solenoid input, make going up and down very smooth.
Image Notes 1. Linear Drawer Rails/Slides that were 8 inches long
Image Notes 1. Air cylinders mounted and ready to be aired up
Image Notes 1. Air line installed for testing in the video.
Step 11: Mounting Components Now that we have the frames built and the air cylinders working together, it's time to really get down to business and start trying to figure out how to shove: (2) Drive motors with 10" Wheels (From Electric Wheel chair) Custom 10" Subwoofer Box Amplifier for Subwoofer Car Radio for powering mids/highs and taking computer input Onboard PC (2) 12v 35Ah SLA Batteries Compressor Air buffer tank Electronics (Solenoid, drive speed controllers, Arduino, power switch, etc) Now if you remember, the Main Stage frame was 28 x 44.5 inches, this means that the drive train frame was smaller, around 25x42" where all of this stuff has to fit. What are we waiting for?! Lets get to it!
