This unnamed robot creation by Frosty Orange performing a full 360 backwards flip from a standing position. Not only that, but it sticks the landing. Pretty impressive for a bipedal bot.
How this great Back Flip Humanoid system work?
Performance while maintaining the air that back, we aim to save energy consumption, frosty said. The idea is to change the ratio of bending the knee of the curve of the servo. With the ratio falling to just stretching your legs when burned, its minutes, to give the pretension of the spring. To increase the weight when standing spring.
In the past the knee with elastic links link was independent quasi-linear, This configuration has been synthesized in the middle.

Gesture-driven robots are nothing new, but this robot arm, developed at Japan’s Tsukuba University, stands out with some impressive tech. The system lets humans control the arm by analyzing the movements of their hands and arms based on a video stream (the arm then replicates those movements almost in real-time). (more…)

This impressive early prototype demands an important place within robotics history as the first motorized dexterous robotic hand. It represents one of the early steps towards making robots more anthropomorphic. The Omni-Hand was designed and built in the early 1990s by robot pioneer Mark Rosheim with funding from NASA contracts NAS8-37638 and NAS8-38417. Two prototypes were made. The first was a “test bed” whose features were then incorporated into this complete unit. Both had the same power and control system.

Two day ago, i bought 12 Tower Pro servos type MG 995R Digital High Torque Servo and today the packet arrived.
Specifications :
MG995R RoHS Standard weight- 55.0g
Dimension 40.7*19.7*42.9mm
Stall torque 8.5kg/cm(4.8V),10kg/cm(6V)
Operating speed 0.20sec/60 degree(4.8v), 0.16sec/60 degree(6v)
Operating voltage 4.8-7.2V
Temperature range 0℃_ 55℃
Dead band width 5us
With stall torque 10kg and metal gear, i can easily use it to drive dexhand v2. At dexhand V1, i used Hitec 311 standart servo with stall torque 3kg and the servos work to hard. So, with this MG995R , i believe Dexhand V2 will move better and smoothly.

The machine draws the calligraphic lines with high precision. Like a monk in the scriptorium it creates step by step the text and writes down the bible on rolls of paper.
Starting with the old testament and the books of Moses ‘bios [bible]’ produces within seven month continuously the whole book. All 66 books of the bible are written on rolls and then retained and presented in the library of the installation.
After successfully build the Dexhand ( Dextrous Robotic Hand) , now i am build new dexhand called Dexhand v2. This Dexhand v2 have same construction and system with V1 but of course have little different to improve the Dexhand V2 function, moving and also operating. So, always check back to this post to know the Dexhand V2 progress.
Above photo is Dexhand V.2 where the design similar to Dexhand V.1. In order to improve the mimicking / imitate function to become more close to human Hand, i have change the thumb design and the number of DOF.
Dexhand V.1 have 3 DOF thumb, now Dexhand V.2 thumb increase become 5 DOF. At other fingers, Dexhand V.1 have 2 DOF, at Dexhand V.2 become 3 DOF each fingers ( Index, Middle, Ring, Pinky ).
So, overall, Dexhand V.2 become 17 DOF, where at Dexhand V.1 only have 11 DOF.
