I-Swarm robot is a fully-integrated and functional micro robot. What makes these robots so impressive is the level of integration; they possess a micro-step locomotion mechanism, a solar cell, custom IR communication modules, and an ASIC (custom silicon circuitry) all in a very compact package.

The locomotion unit consists of a flexible printed circuit board (FPC) with three legs that have a piezoelectric polymer actuator multilayer film on top.

Zipitbot robot uses some motors and a dsPIC microcontroller to move around. dsPIC board on top communicates with the Zipit over an I2C bus and client program is able to control the ZipitBot over a wifi link. There is also a USB webcam attached. [via]

This device can successfully crack a lock by trying the minimum number of physically viable combinations. These locks are classified as “manipulation proof” by their manufacturer. More infomation is available at the link below.

This project is a DIY metal hunting robot that uses a Parallax microcontroller to hunt down metal objects while avoiding bumping into objects. [via]

To avoid any collision with other objects (such as furniture), the robot uses an ultrasonic range detector (radar) as well as 2 side infrared range detectors. The radar, placed on top of the robot, searches the area infront of the moving robot for obstacles. If one is located within close proximity (30cm), the radar scans the area (rotates with the use of a motor) for any other possible paths which contain no obstacles within range. The 2 side IR range sensors make sure that if something misses the range of the radar, a side collision won’t occur.

This project is a part of the Biorobotics research activities at the AILab of the University of Zurich. The main objective of this project is to explore the design principles of biologically inspired legged running robots. In particular this project focuses on a minimalistic model of rapid locomotion of quadruped robots inspired by biomechanics studies. The goal of this project is, therefore, to achieve technology for a form of rapid legged locomotion.

This robot is balancing a standard pencil based only on visual input from two “dynamic vision sensors”. These sensors do not rely on a constant background, as shown when rotating the platform during operation. To achieve the balance it uses two servo motors and two Dynamic Vision Sensors one for each axis. These sensors “watch” for changes in pixel contrast, outputting a positive or negative number based on the direction the pencil is beginning to fall. An NXP2103 running at 64 MHz reads in the values and drives the pair of servo motors accordingly. [via]

Following up “The Open Lidar Project – Hack the Neato XV-11 Lidar” post, we are happy to tell you that the unit is hacked by user Hash79. He and several others (including major contributions from user Xevel) managed to crack both the 2.1 and 2.4 firmware’s output data, including distance info, angular data and checksums. The unit takes 360 distance data at 1 deg increments at 10 hz. It can range up to 6 meters. You can follow the whole saga here: http://forums.trossenrobotics.com/showthread.php?t=4470 .

Big thanks to RobotNV and Trossen Robotics (who both donated $100). RobotShop also offered the refund the cost of the robot if it was bought from them, but Hash79 had bought his unit from Amazon.

There is still an outstanding $200 bounty from RoboDynamics for using the unit for doing SLAM navigation from point A to point B in a room.

gallamine @ robotbox.net offers a $200 bounty to the first person that successfully hacks Neato Robotics’s XV-11 floor vacuuming robot’s laser rangefinder and releases open source documentation/drivers for using it on a robot. This type of sensor would be a great asset to small (and large) mobile robots and it’s a steal for the $399 it costs to buy the Neato robot. He want to kickstart the process of documenting how to use it.
