[Jim Fong] sent in this demo of his version of the UHU servo motor controller. [Uli Huber] has actually shipped over 2500 controllers for the servo. He doesn’t charge much for the chips, and only asks for something like a token beer in return for his work. I used [Jim]s boards in my mini mill controller, so I know he does good work. This servo controller really is a big deal. It can handle high power, and servo motors are *the* way to build a fast milling/robotics setup.
If you’re into Cons, you might be interested that the first round of Shmoocon tickets went up for sale today – looks like they’re already out, so keep your eyes open if you want to go. It’s a decent con that takes place in DC. I know that I’m planning to be there.
[Coley] sent in this port of jetpack for the propeller uc, but when I started poking around I discovered this sweet hybrid robot platform. A four stroke Robin/Subaru 35cc motor drives a car alternator, providing virtually unlimited (in the robot world) power on demand. Hit the video after the break for a quick R/C demo and an idea of how loud the engine is. Offhand, I recognize the lovejoy coupler that was used to connect the engine to the alternator.
By the way, this bot is featured in the latest Robot magazine, so you can get details there if you hate reading forums.
[Max T] sent in this interesting robot design. I dig the combo motion design. The legs can walk, or the wheels flip out time machine style to roll the robot around. Rather than power the wheels, the legs are used to skate the robot around – like a human on skates.
[Gloria] sent in Gottard. (English translation). This little box is designed to act as a stool – that happens to follow people around, record their conversations and play them back to other visitors as a form of interaction. A set of rotating casters provide seating support, while a pair of gutted cordless drills move things around. An Aurdino handles the robotic functions., and an iBook handles recording and playback. Ultrasonic sensors guide the movement, and a set of LEDs roughly show how full the recording drive is.
