Researchers at Zhejiang University in Eastern China have unveiled a pair of table-tennis-playing humanoid robots that have been in development for 4 years. The bipedal twins stand 160cm (5’3″) tall, weigh 55kg (121 lbs) and possess approximately 30 degrees of freedom (7 in each arm). The right hand holds the tennis racket, while the left hands are equipped with three fingers that can grasp and serve the ball. They are able to automatically track the speed, direction, and position of the ping-pong ball using an overhead camera that captures the action at 120 frames per second. With a reaction time between 0.05 and 0.1 seconds and an accuracy to within 2.5cm, the robots were able to successfully rally against each other as well as human opponents.
This is actually a temperature logging System with 8 temperature sensors ( only 4 shown in diagram for simplicity). values of all the sensors are sent via serial by AT89C51 to pc. Software “DAQ System ” takes these values and show them on its front panel, and also logs them to the data base “daq.mdb”. We can set some parameters like set point, low limit and high limit. When temperature of some sensor increases beyond set point ,the heater which connected to controller (specific for that sensor) will be turned OFF ( ON in opposite case ). High limits and low limits are for alarm. when temperature goes above high limit or below low limit the alarm will be turned on.
The source code for the project is written in Visual Basic and C-language. You can download the vb-code , c-code, schematic, and if you don’t have a cross compiler then you can directly burn the HEX file on to your chip DAQ System.zip

Y axis that has already finished forced to be dismantled because of trifles. It’s cause by 2mm problem. So, how the 2mm can make the big trouble so that i’m must dismantle and redesign the Y Axis?
At above picture we can see that at left and right of screw rod haven’t same distance. Left side 17 cm, right 17,2 cm. The difference only 2mm but…..that is a problem. This 2mm will make the Y axis moving with not stable and doing zig zag.

Now, i’m working on my CNC project, an Inexpensive CNC Project. As we know, most of the CNC parts is expensive and hard to find in some countries. With a little creativity and imagination, we can make the cnc with same function but different and cheaper parts. So, here’s what I make.
As you can see at above images, some parts maybe you know and not usually used in making a CNC, but we can used it. These parts is:
In 1986, Honda began the Humanoid Robot Research and Development Program. Keys concepts were “intelligence” and “mobility”. Honda started with the basic idea that the robot “should coexist and cooperate with human beings, by doing what a person cannot do, and by cultivating a new dimension in mobility to ultimately benefit society”. This provided a guideline for developing a new type of robot that would be used in daily life, rather than a robot purpose-built for special operations such as manufacturing.
Like every inventors, they always start with making simple sketch on a paper Read more…

Honda has developed a five-fingered hand powered hydraulic mechanism. Mechanisms applied in the brake master cylinder are using a car. Five fingers working in conjunction with a motor, can grasp objects of different shapes. Since you want to be equipped with smaller motors at each joint. Combines the strength and dexterity as a robot hand for a few know how to keep working.
Japan’s National Institute of Advanced Industrial Science and Technology (AIST) has build new Homanoid called HRP-4. This humanoid is the latest HRP Series with high density packaging technology. The HRP-4 is primarily designed for use at R&D facilities at universities and companies.
Each day work accidents, car accidents and disease are factors which no one is free from suffering so you can lose a hand.
Today other high technology prosthetic arms can cost total up to $59,000 after surgeries, therapies, maintenance, etc. In other words technology is out of reach for the Mexican market, and this is the unattended market that the project seeks to fulfill.
Usually, if we build a machine, it must have a special function. Here you’ll see very funny machine where the machine purpose is only to turn it self off. Very useless right? So we can say, The machine live just to turn it self off..LOL. Just check video below and you’ll know what i mean….
