aggrav8d is building a hexapod called SPIDEE-1, i'm watching the progress he makes and now i think it is time to be presented.
You can check the Facebook page for updates and sourceforge for the 3D simulation environment to control and communicate serially with the haxapod.
It is a very nice effort and a plus to open source community so it worths your click.
Christian Smith shows a demo of ball-catching using a custom robot arm at CAS.
The idea is to cover a large enough area in short enough time to be able to do this.
A 'large enough area' has been defined as a 0.6 m by 0.6 m window, based on the precision of a normal underhand ball toss. A 'short enough time' has been defined as 0.5 s, based on the flight time of ballistic objects and the reaction times of the teleoperated system.
In simulations the robot arm can, if started in the middle of the operating window, reach any point therein within 0.3 s, which should be fast enough and also impressive.
Seeing the video with a bad connection sometimes you wont even see the arm movement to catch the ball, that fast!
Complete documentation can be found here.
Lorenzo Jamone, Matteo Fumagalli and Giorgio Metta from the University of Genoa, work on a project called "Machine-Learning Based Control of a Human-like Tendon-driven Neck".
For this purpose they builded James, a robot able to orientate its head as needed by actuating its tendon-driven parallel redundant robotic neck.
In Lorenzo's YouTube channel you can watch other videos of James learning to reach and grab objects but for the whole paper you must look here.
HiTechnic manufactures a range of robotic sensors for the LEGO MINDSTORMS NXT. The majority of HiTechnic sensors are certified by The LEGO Company assuring the highest standards of quality and safety. In this video they use the Gyro Sensor along with the HiTechnic IR Receiver to make a self-balancing remote controlled robot. It can be built using parts from either an NXT 1.0 or 2.0 set and will even work with the large RCX wheels.
Building Instructions and programs in both NXT-G and NXC for download are provided here.
If 10-15 years before someone told you that one day you could make with Lego balancing robots would you believed him?
marcimatz shows us the Virtual Robot Experimentation Platform simulating the Expliner robot. Expliner (which is commercially available from Hibot Corporation is able to inspect very high power lines while power is on, and also manages to overcome spacers and other obstacles on its way. The Expliner CAD model is courtesy of Hibot Corporation. You can watch the robot in action here.
Bill Porter starting with code originally written by Shutter of Arduino forums and after adding analog stick support, rewrote it into an Arduino library.
In the video he demonstrates using an Xbee radio module to control his track robot.
For a sum of the library features and details you can check here.
Laurens provides us with an easy how-to with simple instructions to make an Lego NXT balancing robot. This works with all NXT sets from older to newer. Check his page and start your own lego pendulum robot right away. :)
