RIght now we use the BaysianMaximization Function In Mathematica to explore the space of Phase offsets and Amplitudes to see how this affects performance of the Robotics Snakes movements [YouTube Video of Snake in Motion][2] #Hardware ##Snake This is a 2 Dimensional Snake Robot that has flexible couplings between each joint so It can rest flat on the surface. There are 8 segments, made using 40mm x 40mm x 20mm metal gear High Torque Servo's that come with the [Roboterra][3] Origin™ Robotics Kit and powered by the RoboCore Board. The is constructed from laser cut MDF, press fit passive fidget spinner / Skateboard Bearings 608zz 8mm x 22mm x 7mm. The design is done in [OpenSCAD][4] and done is a Japanese wood working style, and doesn't use screws, glue or fasteners except for the RC Servo Hub. Design Files here. [https://github.com/johnsokol/OpenSCAD-misc-projects/tree/master/RCservo-snake][5] ##Pulley ![The Pulley System][6] The Pulls consists of an RC Hobby Servo and an optical switch that senses a lever position that moves based on the tension on a string and release more strings as needs till the end of it's travel, just over 8 inches. It then can retract the snake back to a "HOME" Position to restart the next trial. ##Measuring Fitness The fitness of the trial is measured by taking the slope of distance / time. A full run is 20 seconds. If it's reaches the end of the 8 inch travel the time is stopped and reset for the next trial. If it fails to move over some small amount the trial is terminated and results are returned with whatever travel was made. ##Control The communication between robot and Mathematica is done via 2 serial ports in the RoboCore board. The Snake itself is controlled by 2 RoboCores over one USB Serial Interface. The 2 cores are connected VIA I2C interface. #Movement ![Snake Kinematics][7] *note1 The snake moves using passive wheels and diagonal friction against the surface created by lateral undulation, currently these are done using a Sine wave, future versions will use more complex patterns. #Conclusion [https://github.com/johnsokol/WolframSummer2018Project][8] Note1: *Image from Locomotion Efficiency Optimization of Biologically Inspired Snake Robots: Eleni Kelasidi, Mansoureh Jesmani , Kristin Y.

Becker and Javier Garcia. In this simulation, you are some rich gadabout with a limited speed and unlimited turning radius, running for your life. The other player is your chauffeur, with a higher speed and limited turning radius, who has clearly lost their mind. Can you survive? [![homicidal chauffeur][2]][1] [1]: http://demonstrations.wolfram.com/TheHomicidalChauffeurProblem [2]: http://community.wolfram.com//c/portal/getImageAttachment?filename=homicidal.jpg&userId=21530 Ed Pegg 2018-01-23T15:53:33Z https://community.wolfram.com/groups/-/m/t/967268 A new SystemModeler example has been added to the list of downloadable models available on the SystemModeler site, [Binary Counter][1]. Counters can be used for a huge array of applications. They can, for example, be used to count pulses from a sensor attached to a wheel to count the number of revolutions, which in turn can be used to calculate the speed of the wheel. Counters also can be used as digital clocks for different purposes. Another typical use of a digital counter is in central processing units (CPUs), where a certain kind of counter (program counters, or PCs) is used as a way for the CPU to walk through program instructions, one by one, from a memory. Flip-flops or latches are used as basic components in digital circuitry and work as a kind of memory that stores the state of one bit. By using multiple flip-flops, it is possible to construct digital state machines. A binary counter is basically a state machine that just cycles through its states for each cycle of a clock signal. A diagram of the counter component can be seen below. ![Diagram view of the counter][2] The example utilizes a new feature in SystemModeler 4.3. Enumeration types, such as the [logic levels][3] in digital circuitry are now plotted using their discrete levels on the y-axis. This is apparent when plotting the internal states of the counter, for example: ![Digital levels][4] This of course not limited to built-in enumerations. The following custom enumeration type: ![Modelica code][5] Could look like this, when plotted in Simulation Center: ![Temperature levels][6] For more information on what is new in SystemModeler 4.3, check out the [What's New][7] page.

We now have two major categories: Industry Examples and Education Examples. ![enter image description here][2] When you click on one of the topics, say [Mechanical Engineering][3], you get to a page dedicated to that topic: ![Mechanical Engineering Domain][4] For pages with educational materials there are difficulty legends to guide you. There are of course examples that are suitable for more than one level. When you click through to an example, you get to the individual example page, where you can read about the example, see videos, interact with CDF dynamic content, or download the full model. The full model can also contain a Mathematica notebook with analysis and design material. ![Individual example page][5] When you find an example that you want to share on social media, there are new share buttons to make that easy. I hope you like the new pages and take a minute to browse through the examples!

The ball and beam control problem has been added as a new example model at the SystemModeler industry example page, [here][1]. ![Diagram of ball and beam][2] Inside the downloadable model, you can try out different parameter settings. Two different control schemes have been provided together with the model, a PID controller and a LQ regulator. The model also comes with CAD models of the ball and beam that are used to animate the simulation results: ![Animation of ball and beam][3] Additionally the download comes with a Mathematica notebook that provides instructions on how to automatically tune PID parameters and calculate linear quadratic gains from the Modelica model. From the notebook, Modelica components are created that are used to control the ball and beam. ![Mathematica notebook][4] Even more control theory related models are available at the SystemModeler industry example page, such as [LEGO Segway][5], [PI-controlled Tank System][6], [Arduino Robot Arm][7], and [Model Inversion Control of a Hoist Crab][8].

You always wanted to play with those motion capture files that you can find for free by the thousands on places like the [Advanced Computing Center for the Arts and Design][1] or the [cgspeed site][2] which contains BVH conversions of the 2500-motion [Carnegie-Mellon motion capture dataset][3]. Well, now you can. I have written an importer package for the BVH (Biovision hierarchical data) motion capture format, which you can find as an answer on [mathematica.stackoverflow.com][4]. Just three of the possibilities: Import: out = Import[ "C:\\Female1_D6_CartWheel.bvh"] ![enter image description here][5] Generate movies: out["AnimatedGIF", "C:\\cartwheel.gif"] ![enter image description here][6] Analyse motion: Graphics3D[ MapIndexed[ {Opacity[0.8], Hue[#2[[1]]/out["FrameCount"]], GraphicsComplex[#1, Line /@ out["Bones"]]} &, out["JointsStack"] ], Boxed -> False ] ![enter image description here][7] etc. etc. Combined with all the graphical power of Mathematica the possibilities for fun projects are endless.
