I made a new robot this weekend.  It’s not a biped, but it does use Herkulex servos, which are intended primarily for bipeds.  I wanted to see how well they would work as closed-loop gearhead motors.  (That, and I had a Magician chassis lying around just begging to be put to use.) 

I’ve posted about Herkulex servos before.  In case you’ve been living in a cave, these are a new line of smart servos from a Korean company called Dongbu.  I love ’em — they’re strong, compact, affordable, easy to mount, and smarter than even the Other Leading Brands of smart servos. But until now, if you’ve […]

The other day, I configured four Herkulex servos for use at 57600 baud, so I could communicate with them from an Arduino‘s software serial port.  Here’s what happened next. I had previously started on my own Arduino library for communicating with these servos.  Then my brother, whose google-jutsu is apparently stronger than mine, sent me […]

I recently picked up a few more HerkuleX robot servos from Road Narrows.  I love these servos; they have a great form factor, plenty of power for the price, and all the features you’d expect in a modern smart servo, and then some.  Moreover, they have a detailed, clearly written manual written in good English […]

Dongbu Robot, makers of the Herkulex line of servos and the Hovis humanoid kits, has announced two new servos: the DRS-0401, packing 40 kg cm of torque, and the DRS-0601, at 60 kg cm.  That means the DRS-0601 could lift 60 kg (that’s 132 pounds, for the luddites) with a lever arm of 1 cm, […]

This week I finally found the time to hook up the Dongbu Robot Herkulex DRS-0101 servo that I picked up last month at the VStone Robot Shop in Tokyo.  (If you’re here in the States, you can pick these up from Road Narrows.)  After a few missteps, and some fantastic tech support from Dongbu Robot, […]

Robotis, well known for high-end (and pricey) servos like the MX-28, and popular mid-range offerings like the AX-12s used in its Bioloid robot kit, is now extending its product line down to the entry-level market.  As reported by Lem Fugitt at Robots-Dreams, these offerings include a new low-cost controller board, a plug-and-play LiPo battery, and […]

A low-cost, 3D-printed biped robot design known by BoB is becoming a bit of an internet sensation.  It was posted originally on LetsMakeRobots.com, and then on Instructables.com, where it’s received almost 30 thousand views and over 250 favorites at the time of this writing.  That’s sure to increase since it recently won first or second […]

The brains of most humanoid robots are either an embedded Linux board, such as the Gumstix (or, I predict, the Raspberry Pi); or an ATmega328 (or its smaller cousin, the ATmega168).  The former offers a full Linux environment, running at 600-800 MHz, with all the on-board dev tools, file management, and other trappings that implies.  […]

I’ve met a lot of people who want to get into the hobby, but aren’t sure where to start. There are many different kits (and non-kits!) to choose from. Choosing something too advanced for your time and skill constraints leads to frustration and disillusionment. But a robot too simple or limited can become an expensive […]
