This shows the carambot driving around autonomously by using the ultrasonic range finder together with the pan servo. The algorithm used is pretty simple (see Python snipped after break).
This is work in progress, so see it fail . What you see in the video is an update about the robot I am currently working on. It uses a Carambola MIPS SoC which communicates to a MSP430G2553 on a TI Launchpad through serial line. The Launchpad runs a “special” firmware I am currently working [...]
Range finder on server pan tilt looking funny . The servos are driven by a Launchpad with MSP430G2553, as well is the ultra sonic range finder. The range finder is a SFR05. I am planning to implant that PTRF (pan-tilt-range-finder) into carambot to make it drive autonomous.
I wrote up my learnings on how to drive a servo in a little tutorial. The tutorial describes how to drive two servos (e.g. for a pan-tilt unit) through a PWM signal on an ARM Conrtex-M3. The example firmware described uses “libopencm3” as a basis. See the video below to get a glue what the [...]
