AndyMark

The biggest time investment during my internship was the development of the S3 Kodiak, a fully functioning, field legal FTC robot for the 2021-2022 game, Freight Frenzy. The robot was completed entirely by me over the course of roughly a month, at first using existing AndyMark products, and then modified to use new additions being developed in parallel like the TileRiser chassis. A key part of Kodiak's development was tracking the entire design process. A 50+ page document was the final deliverable, detailing things like game analysis, design decision making, fully commented Java code for both teleoperated and autonomous modes, and every stage of the CAD. Kodiak was additionally used to develop videos for AndyMark's "How Do I...?" video series.

The focus of my internship was on concepting, developing, designing, building, and testing the TileRiser FTC chassis. TileRiser is a high-clearance alternative to AndyMark's TileRunner drivetrain, compatible with many of the company's 4" wheels and using the existing S3 system for backwards compatibility with previous AndyMark products. The TileRiser chassis also reduced the complexity from TileRunner significantly, shifting from 2 sets of 2 similar sheet metal pieces to 4 identical sheet metal pieces. TileRiser also implemented new geometry to make the product more robust than its TileRunner equivalents.

The WCD bearing block is intended to be an alternative to VEXPRO's versablock for WCD systems. It fits snugly over 2x1" square tubing and uses the pressure applied by 4 bolts to adhere to the material without the need for mounting holes. The central hole is shifted slightly to allow for "center-drop" drive systems to improve a robot's turning capabilities. The bearing block also features "nut-pockets" that fix the orientation of nuts in place so a wrench is not needed to attach or remove them.

During my internship, I constructed an FTC robot for the 2021-2022 game, Frieght Frenzy, using only AndyMark's S3 building system. Over the course of the project, I identified several key pieces that were missing from the system and developed new products to fill those holes. My work comprises the S3 gussets released last fall.
