Step 14: A few notes on working with Rhino

This Instructable isn’t the right place to go into a thorough Rhino tutorial, but a few tips might be helpful.

This enclosure was almost completely designed using boolean operations on NURBS surfaces. So the first step was to create a box that was the right overall dimensions (150mm), then boolean intersect it with a sphere that provided the most satisfying curves. To hollow out this shape, it's necessary to create an offset surface or to simply subtract a smaller version. Unfortunately, Rhino won't let you remove one volume from the inside of another volume, they need to intersect. Also, creating an offset surface can have poor topology compared to the surfaces you get from constructing it from scratch. It's essential that the outer layer of the enclosure has good topology for making good connections to all the posts on the inside, so after testing a few different approaches we went with manually constructing a second smaller version from another cube and sphere, and creating the negative space for the single hole out of a cylinder. After boolean unioning the inner portion with the cylinder, we could boolean subtract it from the larger portion and maintain good topology. Later we realized a cylinder would mean that any cap would just fall in, so we repeated this steps using a cone instead so the hole's walls would have a slight tilt.

<p>can you answer me please i am in eighth grade and I am making this for language arts. ASAP</p>
<p>how long did this take you</p>
<p>may price more than 10 k INR</p>
<p>What is the total price of this?</p>
<p>i really like the design. very well made! </p>
<p>ain't there a video for it? i wanna see it moving @_@ please :|</p>
Does someone have the message: &quot;Cannot read property 'HITId' of undefined&quot; when executing app.js ?
<p>Have you ever considered turning this into Wheatley from Portal 2? that is my ultimate goal for this.</p>
<p>I did some computer vision on the raspberry pi. For instance face detection and feature tracking. I am working on improving it until it is not using all of the raspi computation power, which is currently the case.</p>
<p>Great project and instructions.</p><p>Im confused on how the noodle actually processes events. What is the response time? Can I make it automated or does it have to have a real person always?</p>
<p>Response time from Mechanical Turk is around 5 minutes, but if you follow this Instructable in general and then substitute your own Turk form that posts directly you a dtabase/service you have set up, then you can get the response time down much lower (maybe 30 seconds).</p><p>Some basic things can be done automatically (like motion detection or basic speech to text) but we were focusing on the manual things.</p>
<p>Am sorry if i skipped but i found no video of your robot. A video would be really nice.</p>
<p>There isn't a video, mainly because the pictures are more representative :) The video would mostly show it playing sounds or putting pictures on the screen, or doing something more digital with the network.</p>
<p>brilliant!</p>
this is amazing! It never ceases to amaze me what people can do with a raspberry pi - you are a genius
<p>Need a video of the robot please!</p>
Oh,so intreseting
<p>Great job!</p>
<p>Amazing. You should enter in a contest. You'll be sure to win something</p>
Love it.
