Harvey Mudd Combat Robotics Tutorial Bot

This repository contains the finished CAD model of the tutorial bot. Information on how to lead the tutorial is in this file.

Looking through this and creating the bot yourself before leading the tutorial would be smart.

First half of the tutorial

Estimated time, 1 hour

In the first half, everyone starts by remaking several part files.

1. support_bar: walk everyone through this one, as it's the first part.

2. 6_inch_wheel: Here we learn about rotating around a line, and also get to look at the material picker in detail.

3. top_plate: The countersunk holes need to be in the right place, people can cut any design they want into the material. Before, cutting the design, have everyone check the mass of the plate. After, recheck the mass.

4. wedge_piece: This is the hardest to sketch. Several angle dimensions are necessary, and figuring out how to get the right angle both ways is a bit tricky. Additionally, have everyone initially make their wedges steel, then after measuring the mass switch to titanium..

5. The rest of the pieces don't add much to learning about the robot, so we'll give those in the next tutorial.

Second half of the tutorial

Estimated time, 1.5 hours

In the second half, everyone assembles the parts together into the finished bot.

1. Everyone needs to download the repository here, and then delete the file robot.SLDPRT

2. If people made their own designs in the first part, they can replace those files with their own

3. Everyone creates a new assembly and imports the bottom plate, nut strips, and support bars in, using the thumbtack tool.

4. People attach all those parts, learning about concentric mates and coincident mates.

5. People import the rest of the parts and attach those using concentric and coincident mates.
