Not only are the Duckiebots amazing to watch but their entire build specification, and even the specification of the layout of the ‘towns’ they drive in, is completely open-source and expanding in design and implementation at the Duckietown website hosted at MIT. Using a common camera module for Raspberry Pi 2 in conjunction with rviz software, the entire robot build and subsequent curriculum for teaching with them are available here; note the links are Google Docs (with some being edited online while I am typing this!) with ‘static PDF’s of the latest available edits also available for teacher-types looking for static content.

Adafruit 16-Channel PWM / Servo HAT for Raspberry Pi – Mini Kit: The Raspberry Pi is a wonderful little computer, but one thing it isn’t very good at is controlling DC Servo Motors – these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these signals, pop on this handy HAT! It adds the capability to control 16 Servos with perfect timing. It can also do PWM up to 1.6 KHz with 12 bit precision, all completely free-running. Read more.
Adafruit DC & Stepper Motor HAT for Raspberry Pi – Mini Kit: Let your robotic dreams come true with the new DC+Stepper Motor HAT from Adafruit. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control. Read more.
