From the projects' kickstarter ($104,217 pledged of $5,000 goal):

uArm is a 4-axis parallel-mechanism robot arm, inspired by the ABB PalletPack industrial robot arm IRB460. ($185 for complete black kit and a gripper)

The basic design is Arduino-controlled with 4 degrees of freedom. Three servos on the base control the main movement of the arm and the mini servo on the top moves and rotates the object. The end-effector of the arm is always kept parallel to the ground.

Right now we have already developed a Windows application that allows the uArm to be controlled with keyboard or mouse. 

With some basic controlling skills, you can use basically any input device to control it, for example, we have also used other remote controller to control the arm. With our imbedded inverse-kinematics algorithm, the uArm can be precisely controlled using coordinates. 

We have also written an Arduino library specifically for controlling the uArm. So if you are familiar with Arduino, you can program it directly with Arduino IDE. By calling different functions, you can easily move uArm to your desired position without doing tons of hard math... cont'd

New KUKA Robot: KR 3 AGILUS Maximum performance in minimum space

Great advances often start with small steps - in manufacturing cells measuring only 600 × 600 mm. Here, the KR 3 AGILUS is in its element. Particularly in the case of small parts and products which must be produced in a minimum of space. KUKA expertise, concentrated into the smallest of spaces, is setting new standards for the 3-kg class. The lightweight robot masters various tasks with agility, dynamism and maximum precision, leading to high flexibility in production - even when it comes to extremely narrow spaces.
