Spider Summary Report

The Spider Summary by mroxo7

Contribution of Team Members and Other Info

We hope to have the finished 3D printed parts within the next couple of days, in time for the presentation this Friday, the 13th. Since the spider is close to being completed we will display the contributions of each team member and the approximate total hours spent. The division of labor for this project was the following:
Chris Tiani-programming of spider, designing of spider in blender, blog post (16 hours)
Chris Beale-designing of spider in solidworks, blog posts, project summary report  (14 hours)
Mat Roxo-designing of spider in solidworks, blog posts, project summary report  (13 hours)
Devin Westmacott-designing of spider in solidworks, project summary report  (12 hours)

The total amount spent on parts for the spider was about $50. The purchases made include: 30 micro ball bearings, 15 servos, and the RF M4 receiver and remote. The group still needs to purchase screws/bolts to put all the parts together; we estimate this will be less than $10. We are waiting until the parts are finished printing, so we can get the correct sizes.

A final blog post for the project will be made once the spider is completely finished and functional. This post will include pictures of the completed assembly, a video of the spider in action, an assessment as to how well it works and what improvements we would make based on its performance.

Parts are all finished now. Here is an image of what we hope will come out of the 3d printer.

and a nice render, the actual scale will be something like 10 inches long with almost a foot legspan if all goes well.

Project update and code

Unfortunately, our servos still have not arrived, and may not for some time. If the servos do not arrive within the next couple of days we will just buy them from an electronic store. We have completed as much of the programming as possible, since it can only be completed once the servos arrive. The code for the spider is shown below.

Note: anything to the right of the "\" symbol indicates the comments.   

This code causes 2 motors to be able to toggle independently between the left state and right state. There will be a lot of changes for the final spider, but this is a proof of concept for the isoMax forth multitasker; it works very well. Another post including the update on the servo situation and the final coding for the spider will be in the near future.
