Half man, half (ant, beetle, grasshopper, cockroach…), the ultimate dream of creepy sci-fi locomotion. I’m sat here with a 6 legged centaur like image in my head, somewhat like the Scorpion King from The Mummy (exceptional 1999 CGI). Probably about the strangest intro to a post I’ve ever written but hey! It’ll do. This is […]

Today, my Swarmbot PCBs arrived! I’ve put one of the robots together to get a feel for where everything would go and what it would look like so its not too pretty but it seems to be functional and I’ve got the robot working autonomously in obstacle avoidance mode using the front IR sensor. Build […]

Servos are interfaced through PPM with the standard generally being deemed as a pulse between 1ms – 2ms and a period of 20ms. I’ve written code before for the STM32F0 discovery boards to allow servos to […]

Sunday, everybody’s least favourite weekend day at the thought of having another 5 days until time is no longer scarce! I’ve been getting down to a fair bit of VHDL programming, one program I wrote recently was an attempt at a brushless DC motor. I managed to get the outputs 120deg out of phase but […]
