Robot Army : Push Notification Dance

How awesome would it be if you had an adorable little robot bob up and down to let you know when you receive a tweet, message, or get an update on a feed? SUPER AWESOME!  In order to provide a more utilitarian use for our delta robots, we’ve mocked up some example code that scans JSON packets from the internet in order to trigger a response of some sort.

For our first project related update Mark wrote code that causes a delta to dance around every time we receive a new backer for our Kickstarter (our robots should be as happy about that as we are). We let this application run all day on Tuesday to test the reliability of the code, however by doing this we apparently opened a rift of unfortunate irony… and didn’t receive a single backer ALL DAY long. This resulted in one very sad stationary robot and two very discouraged drunk engineers.

The good news is that in spite of our brief plateau, the code DOES work… and our test robot is the first one to know when we receive new support from the world.

Over at SYN Shop… our window display yet again underwent some unexpected trouble. After replacing the outdated arms on our three torture test robots, we left them for the weekend to… well, be tortured. They were working fine until someone from the hackerspace emailed us Monday with news that they were once again in piles. ::sigh:: When I stopped in that night I was pleased to find that this round of failure was not due to their joints, rather the new servo brackets split in half (odd). It turns out these new brackets were a hair too thin, and the PLA does get a little dry over time. The dryness caused the new tighter joints to bind up, which put strain on the brackets and over time cracked them.

Once more I scooped my children into my arms and drove them home to be tuned up by daddy. He figures the solution is… more lubricant (of course).  This is what a torture test is all about though, so I’m glad we’re getting the chance to iron out these bugs.

Anyhow, over the past two weeks since the launch we’ve gotten many requests for more detailed information about our machine. If anyone is curious, here are some specifics about the yellow beast :

What are the robot’s dimensions?  The delta robot is approximately 20cm x 20cm wide, and 20cm tall when at rest (a little less than 8” x 8” x 8”).

What is the end effector’s range of motion?  The end effector can reach a diameter of approximately 28cm (about 11”) and can travel up and down on its z-axis 13cm-15cm (about 6”).

How much weight can the robot hold? The robot is able to lift around 12oz (a can of soda) with its end effector.

How fast can the end effector move? Running at full speed, we were able to clock our delta moving approximately 150mm/sec on its z-axis (up and down), and 250mm/sec on its x-y axis.

Having done this, I felt inspired and drew this a few days ago :

Now that we’re at the halfway point of our campaign… Mark and I are starting to get hungry. We keep reworking our marketing strategy every couple of days in order to reach new audiences. Our plan this week involved making a Facebook page for our LLC and investing in some paid advertising………. you know- the annoying links on the right column that try to profile you (for my demographic its engagement ring ads and stuff to do with babies). I have no idea how this will work out for us, but we figured we’d give it a try.

If you haven’t done so, check out our campaign : Robot Army Starter Kit
