I built this format with the lego Robotics Invention System, when I was 12.I was exploring alternatives to Sojourner's 6 wheeled model, combined with self-leveling system of NASA's Crawler-Transporter, emulating theories of locomotion of insect nervous systems using pneumatics. https://t.co/U9CHorpB9g
I'm really impressed with advancements in motor and motion control systems since then. It wont be long until we can build stuff like that with 3d printers.https://t.co/pNirf1li5d
I actually came up with this method of self balancing via a pendulum while investigating ways to get a 2 legged walking robot. Using a pendulum to find 'level' was a meme going around lego circles in my youth.https://t.co/uvONwQAEiH
Dynamic pendulums are fascinating.https://t.co/uDlh0a62uM
This was published about a year and a half before I got my RCX kit at Christmas.https://t.co/Ed3RM9RzAN
I learned to code "Not Quite C" because I needed to use it to have the RCX brick send out IR pulses to the light sensor to measure distance to the stabilized inverted pendulum. Another motor controlled valves for pneumatic system to control 'hips'.BEAM robots were so cool.

This talk discusses the problem of hips and how they lead to twisting motions. They solve the challenge of 2-legged walking robots without pendulums.The resulting absurdity is adorable.https://t.co/FgE0eoXGSM https://t.co/nwdsZlwODN
This isn't to say they don't understand pendulums. They have an older TED talk discussing the nature of pendulums in locomotion that influenced much of their work.https://t.co/uO0C78RDMG
But I think the more amazing thing to me is how quickly someone is able to build a 3d-printed one. https://t.co/nf10QTXCoK
BEAM robots are really cool.https://t.co/82aGkvTNhn

I was 16 years old when I figured this out while trying to build a lego robot to walk in 2003. Trying to help my disabled grandmother as a child, and now using what I learned 20 years later to help my self. Funny how that works. https://t.co/FjBHkMH5Fw
A friend of mine danced to "pendulum slam" once. It was really funny and made me laugh."We're marooned on a small island, in an endless sea,Confined to a tiny spit of sand, unable to escape,But tonight, it's heavy stuff" 🎶https://t.co/3PYuvbTBZM

I had one of those little rubber dart cannons from the cyber slam lego kits. It was one of the first 'guns' that lego ever included in their sets.https://t.co/G7RWLdQ7mM
You can also make a remote controlled lego cannon that you can aim by waving one wiimote around while using another to get feedback.https://t.co/kEwJqUmdgX
