Here is my second pass at running my Trossen PhantomX MKII with a Raspberry Pi. I’ve finally decided to give it a name…. “Charlotte.” It’s called “Charlotte.” It’s running a custom c++ port of the Phoenix software developed by Jeroen Janssen, Kurt Eckhardt and Kåre Halvorsen. All the Inverse Kinematics are calculated on the fly using the law of sines on the RasPi. This version is all floating point and standard math libraries are used. Communication to the servos are done with a USB2AX created by Nicolas Saugnier and using a modified Robotis Dynamixel SDK. Power to the servos is provided by the Robotis SMPS2dynamixel. Remote Control is handled by a USB XBee module and Arbotix Commander.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
