Anthrophex – Update 8-10-17

Its been a ton of time since I last did any updates on the ol’ human sized hexapod! I finally decided to go for dedicated motor controller ICs (Allegro A4950) as opposed to a discrete solution. These chips were pretty expensive (~£27 for the entire board…) driven by an STM32F030 once again generating software PWM. […]

I was originally going to use flex sensors on the joints to measure the angle of each joint but after […]

Anthrophex: Part 2 – The build

Anthrophex: Part 1 – The design

Half man, half (ant, beetle, grasshopper, cockroach…), the ultimate dream of creepy sci-fi locomotion.
