Piwars 2020 The Roof Rack
The State of The Robot
When this video was recorded, I was building the camera mount for the robot. I’d realised I’d need to adapt the robot to different situations, and I wanted to make it field adaptable.
I’d attempted a pantograph type folding assembly, sliding carriage types - all in my head and on paper. None weere quite right. My intent was not to need a screwdriver to make these changes in the field, and just use a few choice Lego parts to make the different modes the robot could be in.
I used Fusion 360 to prototype these ideas, and printed the first attempts at frictin fitting, something that was not Lego, and came to the conclusion that making something Lego compatible with the Technic system would be easier and give me far more flexibility. It means I can consider Lego for building more complex mechanisms and interfacing them with my robots. Mixed mode.
I designed and made an adaptor for Lego Technic Pins that bolts to the top of my lunch box. I printed this on my Flashforge Finder 3D Printer. I nicknamed this part The Roof rack. And it works a treat.
