MIT's Modular Robotic Chain Is Whatever You Want It to Be

Evan Ackerman for IEEE Spectrum:  As sensors, computers, actuators, and batteries decrease in size and increase in efficiency, it becomes possible to make robots much smaller without sacrificing a whole lot of capability. There’s a lower limit on usefulness, however, if you’re making a robot that needs to interact with humans or human-scale objects. You can continue to leverage shrinking components if you make robots that are modular: in other words, big robots that are made up of lots of little robots. In some ways, it’s more complicated to do this, because if one robot is complicated, robots tend to be complicated. If you can get all of the communication and coordination figured out, though, a modular system offers tons of advantages: robots that come in any size you want, any configuration you want, and that are exceptionally easy to repair and reconfigure on the fly. MIT’s ChainFORM is an interesting take on this idea: it’s an evolution of last year’s LineFORM multifunctional snake robot that introduces modularity to the system, letting you tear of a strip of exactly how much robot you need, and then reconfigure it to do all kinds of things.   Cont'd...

ST Robotics - R17HS-6, the 6-axis version of the high speed R17 variant

The 6-axis version of the R17HS high speed variant of the R17 robot is now available. As is our policy the 6th axis is an optional bolt-on module. At the same time we have made it even faster and new software eliminates shake and greatly improves repeatability as this video shows. Please see https://www.youtube.com/watch?v=3wG0MeiJ-yE. The video would seem to imply a repeatability of 0.01mm but we are sticking with 0.2mm in the spec. The motor specialist was able to tune the motors from the other side of the pond. My first reaction when we put power on and entered the first commands was to jump back in amazement (and maybe an expletive). Tip speed is now 3m/s; that's 3 times as fast as its nearest competitor yet costs half the price. I love it when a plan comes together.
