After switching our chassis (and nearly the entire robot) to Actobotics, we are painstakingly converting every STEP file from Servocity (https://www.servocity.com/step-files) into .prt and .asm files in Creo Parametric. We need to do this because you cannot preview STEP files in Creo before opening them, but you can for .prt and .asm files.

However, Creo can convert .STEP files into .prt and .asm files, you just have to do them individually. When we started there were 852 files. It takes about 10-12 seconds to convert each one. This is the 5 billionth reason why I will never work for PTC.

By 12/31, our CAD looks like this. We have the chassis, the harvester, and the harvester wall. Due to time constraints, we will not be making everything (like the length of axles, number of axle hubs, etc.) perfect, and will be guess-timating many measurements. This will be OK for the qualifier, because North Texas is a pretty weak region, and the qualifiers are pretty easy to pass with a working robot. Even having a CAD model should give us the PTC design award, and put us in contention for Inspire 1st or 2nd.

By 1/1, we have a robot with wheels, and we added a linear slide and some motor mounts and motors. We also have the sprockets, but we will not be using chains for the CAD.

We also used math cad to make predictions on how the range would be affected by the distance and the horizontal range of the robot.
