Asimov wrote "a robot may not injure a human being, or through inactivity allow a human being to come to harm," but some of our robotic war machines are already challenging that. As a counterpoint, let's take a look at the bots that were created to help care for us. The softer side of bots, if you will.
The Rescue Octobot
As part of a broader European research initiative into building a full-body octopus robot (why?...why not!) Italian researchers have made a breakthrough  in producing an artificial robotic arm that's unlike most you've seen before: It's a pseudopod! The idea is that the amazing gripping powers and incredible flexibility of an octopus tentacle would be extremely useful for many kinds of robot manipulators. The trick was to build the arm out of softish silicone and embed steel and nylon cables inside it.
Ultimately, octobots could be hugely useful in search and rescue operations in watery environments--being able to maneuver into very cramped spaces, and grasp and maneuver (firmly but gently) anyone who needed rescuing.
An early prototype is shown here:
The Soft-Skinned Robot
Most android robots, unlike octobot, tend to be hard things made of plastic and metal. This causes problems when they have to operate in human environments, where our own softer bodies are at risk of injury when something goes wrong. Which is where Japanese robotics startup Touchence  enters the story: They've designed a synthetic skin, called ShokacCube, which is actually a touch-sensor embedded in a soft pliable material. Strapping it to the outside of the robot's body acts as a cushion to protect anything the robot impacts (and the robot itself) while also providing touch feedback data smart enough to detect if you're stroking it or pinching it.
The most obvious implementation would be in health care robotics, where robots will interact and in some cases move patients around in hospital care situations.
The Nurse Bot
In the future, nursing robots may do many things in hospitals--perhaps even administer medication to patients. But to start, the earliest implementations may involve helping the social needs of patients, making them feel less isolated. One way to do this is via telepresence, and that's roughly what iRobot is getting into with a newly announced  partnership  with InTouch Health. InTouch already operates in the telepresence telemedicine game, and with iRobot's success in other markets the two firms really could make a big impact.
Work will center on the iRobot Ava  "mobile robotics platform" and most likely result in a sophisticated robot able to roam around and allow a remotely located doctor to interact with a patient via webcam-like chats. In terms of bringing specialist advice to patients from far away, this could be revolutionary...but it's also easy to imagine Ava roaming the wards at night, allowing nursing staff to check in on patients.
The Jedi Lightsaber Bot
We couldn't do a whole "Week in Bots" without showing a cool, more menacing robot in action--so here's some research into smart robot arm movements by Stanford researchers, and their experimental robotics course. JediBot is designed  to use pre-defined attack patterns, and when it detects an impact it'll react to move its sword out of the way, which is challenging compared to the usual precise movements of robot arms. In a defensive mode, the robot sees the attacker and sword using Microsoft Kinect, in order to work out the best defensive moves to make.
Fun! Until you remember how deadly Star Wars' droid commander General Grievous  was...
