Six-legged Robot Teaches Itself To Walk

rabiddeity writes "An undergraduate at the University of Arizona has built a six legged robot from scratch. The robot, which is equipped with sensors on each foot, teaches itself to walk and orients itself via an onboard camera. A similar design might be used to explore unstable environments such as collapsed buildings or rocky landscapes."

      This is similar to a stiquito in only the most superficial way -- its a movable machine with 6 legs. In every other way its different.

      Controls: The stiquito has a single (or sometimes two) actuators, that are placed to mechanically, repeatedly cause the same walking motion. This student's robot has 12 actuators, 2 joints on each leg. This makes the robot much more versatile, but also makes the control problem much harder to solve.

      Learning: A stiquito is dumb -- you attach the SMA to the legs, and put a current through to tighten them. It works exactly the same every time, and you have to put it together in just the right way to make it work. This robot is self-learning (or more exactly, learns through reinforcement). The designer simply creates a fairly simple algorithm that has it try motions and see if it gets it to move in the desired direction, and then learns how to do it over time.

      While I think its fair to say anyone with some mechanical aptitude and knowledge of machine learning could put something like this together, its not exactly a simple feat and is certainly impressive for an undergrad. I don't know of any other self-learning six-legged robots (reflecting my ignorance only), but given the capabilities plus the (likely?) low cost its nothing to sneeze at and could have uses in things like disaster operations.

      The configuration of the robot is not the accomplishment here, its the fact that robot can actually learn to walk on its own. As the article mentions; if a leg is damaged, it an re-learn how to walk without that leg. Most if not all hexapod robots would have a lot of trouble moving at all if one leg, or even two, were damaged. Based on what this thing seems to be capable of doing, that would only only probably mean a few minutes of down time before it started moving again. IT wouldnt have to be manually re-programmed to walk again without those legs. This is great for things like interplanetary robots where a single command takes weeks to transmit, when they dont even know if the robot is stuck until it has no way of getting itself out.

When the terrain is too rough or uneven to roll, it's just a matter of locking the wheels and walking.

I could see where that approach would be beneficial to planetary rovers as well as certain military applications.

      No, for one the hexapod in question is made with Dynamixel servos from Robotis, not the "hobby" servos on the MSR... it's also running a dual-core Atom CPU (Z530 if I remember) vs. a PIC microcontroller, and he is actually using that CPU to do some nice vision processing (optic flow). The MSR is a nice hexapod design, but this newer hexapod is quite a bit more powerful.

      Also the Dynamixel servos are an important upgrade IMHO

      This is because they have digital communication with feedback, so the robot can actually sense its "muscles". The common hobby servos, even the ones advertised as "digital", only have one-way analog communication, so all the appendages are blind... no idea if it has run into something, and no idea how hard it's working. [*] Also, there's no way to adjust controller parameters in the servo, for example to make it soft for interaction.

      But these servos are also a new technology, and the student in question (Matt Bunting) has done some extra (and nicely executed) work of his own in order to interface with them. (I've been corresponding with him about this interface board)

      [*] Actually, I believe some Hi-tec servos are starting to include some funky methods for requesting an analog position check or switching into a digital communication mode, but these are poorly advertised and documented, and require support on the servo controllers which drive them, and even so aren't as well designed as the Dynamixel interface, so it's still kind of moot.

      If you had ever actually tried to build a robot, you would have found that simulation and real life are two completely different arenas. Building a path planning simulator for a "bug algorithm" is trivial. Implement it in hardware and you can't abstract away the noisy sensors, wheel slip, and no localization. The problem becomes Very Hard. The same applies to building a robot which can teach itself to walk, whether it's a hexapod or a bipedal robot. Doing it on a minimal budget when you don't have the resources of a large corporation like Honda borders on miraculous.

      I worked with the designer on optic flow algorithms in the same Cognitive Robotics class last semester, and got to see the hardware and source code up close. It uses OpenCV and Lucas-Kanade optic flow to figure out if it's making forward progress. The legs are built using a 3D printer in the lab. From the number of failed and abandoned projects I've seen, completing a project like this would be impressive even for a grad student. Matt is finishing his Bachelor of Science this semester.

      Brooks is one of the most highly influential authors in the field of robotics, but I've read the Angle and Brooks paper on "Small Planetary Rovers" and it says nothing about their robot teaching itself to walk. Their robot has sufficient sensor input to determine its orientation and position in space, but the paper says this information is used for path planning, not low-level movement. Brooks' subsumption AI in the 90s relied on having layers of programmed behaviors which could override each other. My guess is that Attila was preprogrammed with instructions on how to move its legs: i.e. lift legs 2 and 5, rotate these actuators to these positions, drop legs 2 and 5, etc.

      The cool thing about Bunting's robot is that the robot has no conceptions of what combination of leg configurations results in forward movement. There are probably some prior constraints on how many legs should be on the ground and how many should be lifted, and maybe some information on the range of motion for each leg (although it appears the robot figures that information out itself as well).

      We describe an algorithm which allows a behavior-based robot to learn on the basis of positive and negative feedback when to activate its behaviors. In accordance with the philosophy of behavior-based robots, the algorithm is completely distributed: each of the behaviors independently tries to find out (i) whether it is relevant (ie. whether it is at all correlated to positive feedback) and (ii) what the conditions are under which it becomes reliable (i.e. the conditions under which it maximizes the probability of receiving positive feedback and minimizes the probability of receiving negative feedback). The algorithm has been tested successfully on an autonomous 6-legged robot which had to learn how to coordinate its legs so as to walk forward.

Do remember that universities are having their budgets cut left and right. Might do some good if people were reminded that cool, commercially applicable, stuff can come from them.

    Also, if all you saw was 6 legs, well you didn't look very hard. The reason Intel's interest was peaked was the legs, it was how it works. That Stiquito is a simple device, probably a finite state machine, that just does the same thing over and over. Notice that what it has no sensors, just an on/off switch. You turn it on, it follows whatever program is in there to move forward. Not the case with this thing, it uses its camera to see what is happening, and then figures out what to do. It is actually processing data and adapting based on that. Much, much more complex.
