Thus far in ME4823, we have conducted essentially all data processing, algorithmic decision-making, and higher-level control on the laptop, and only communicated with the Turtlebot to issue actuator commands (/cmd_vel) and to receive sensor data (/odom, /amcl_pose, /rfid, etc.). In this package, we accomplish two major tasks: (1) Transfer ROS Packages onto the Raspberry Pi Model 3B Single Board Computer (SBC) so that the only means of issuing commands is by establishing a secure shell (ssh) via laptop; and (2) Develop a Control Algorithm in MATLAB’s Simulink to detect an “undersea cable,” which will be simulated by a row of RFID cars taped to the floor. The laptop represents the “manned submersible” and the TurtleBot represents the AUV. The ThingMagic RFID reader represents a towed magnetometer, although field intensity is not measured; instead, only presence of the “magnetic field” or RFID emission is detected. We will remove other RFIDs from the area of operations (AO) to simplify things.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
