Robot Videos / AUTONOMOUS - Award-winning Sci-Fi Short Film
« Last post by Spacefarer on October 05, 2016, 09:25:14 AM »
AUTONOMOUS is an award-winning Sci-Fi short film that unofficially premièred at the 35th SGAI International Conference on Artificial Intelligence at the University of Cambridge.

It recently won the Silver Award at The Box Film Festival 2016 (UK), and is an official selection in ten more film festivals around the world.

Premise: When a mistrustful rogue, who earns a living by sending “obsolete” humanoid robots to the scrap heap, has a change of heart and decides it's time to call it quits, he stumbles upon a conspiracy that will reveal his life's darkest secret.

Electronics / Choosing the right equipment
« Last post by BS235 on October 04, 2016, 05:28:25 PM »
Hello!  I am new to robot building/automation but have some experience.  I have purchased a motor from Maxon Motors and I am currently trying to use their EPOS2 70/10 positioning controller for this project.  I have been advised to use a PLC as the controller does not possess the capability to do what we need.

The project is very basic but it seems difficult to find a controller with a simple way to integrate this. 
The project:
A small car is captured with wheels on a track.  A motor is at one end of the track, and an idle pulley is at the opposite end.  A rubber timing belt makes a loop.. it starts at one end of the car, passes around the motor pulley, back under the car (unattached), around the idle pulley, and then attaches back to the car. This way, when the motor spins left or right, the car travels left or right on the track.  The motor is driven left or right with a joystick. The user will be able to control the speed  and direction with a slider knob and from pressure on the joystick.  The controller should set software limits to keep the car from traveling off either end of the track.  This needs to be done from encoder positions, not from any external sensors.

So.. this is all relatively simple.  The difficult part is this.. Getting the car to stop at the end of the track at the same position, regardless of the speed it is traveling.  This is simple in controllers when commanding a position to travel to, but I cannot find a controller that will allow you to accept a joystick signal (+/- 10v, pwm etc) and still have speed sensitive end limits. 

The answer I was commonly given is to use a microcontroller to develop a lookup table that would constantly monitor the position and trigger a deceleration at the appropriate encoder count.  This would require a lot of R&D and change drastically dependent on payload on the car.  I know that there must be a simple way of doing it and some expert out there knows it. 

The only other challenge is it must incorporate a dual encoder feedback loop.. but the EOPS2 controller already has that integrated. 

If anyone has some solution to drive this system, I would really appreciate the advice!  Thanks!

Software / 3D Hydrodynamic Simulator

Hello,

I am working on an autonomous underwater robot. The robot's method of propulsion is designed to be inspired by biological forms such as fish and eels. I have been looking into software that would allow me to create an animated 3D model of my design and place it into a water tunnel to determine how efficient it would be in the water.

My question is: does anybody know of any good software that would facilitate this? I have looked at Maya as it has wind tunnels as examples but it is very confusing for a first-time user. I have also looked at fluid simulations on MATLAB but they don't seem to do what I want.

Also, if anybody has any information on a better way to determine the efficiency of the design, I would be happy to listen.

Thank you,

Mark A

We are good now. I used another PC with Norton Anti Virus and the files downloaded just fine.

Thanks

Can you make a Tutorial about making a Robot that can dig for Gold and from the comfort from your home?So, I won't have to go to the river and dig up gold myself?Oh and the robot would have a live video stream (so you can watch it doing its job live) and a tracking device so You Know that the robot is doing its job and you won't loose it

Mechanics and Construction / What materials would I need to make this type of robot?
« Last post by DObluefire on September 30, 2016, 07:47:34 AM »
I'm planning on building a robot that can dig/pan for gold in the river, I joined a robotics club a while a go

But I want to know the type of materials I need here's what it's suppose to do

-Controlled by my voice
-Uses a pan to pan for Gold
- Uses a Shovel to dig up the Gold
- Uses a phone for Camera
-Uses a tracking device so I can track it
-Uses a separate phone, for the voice control (or another Device that can be used for voice control)

It's Hand will be like a Human Hand with Five fingers and all

Electronics / New Advance of AI, Cookid intelligent humanoid robot

When it comes to artificial intelligence, The first thing come to our mind is humanoid robot, not as simple as the industrial robot that made up of intelligent machines but appear in the form of humanoid form that can interact with people.

 

Intelligent humanoid robot is a kind of service robots, why do we say so? Most industrial robots are mechanical arm but family services, entertainment and educational robots are mostly humanoid. Humanoid robot is supposed to give best experience, both in ideology and sensory experience.

 

Humanoid robot is not a pile of mechanical parts and chips, in previous research on robot, it should be able to do housework, use the arm to grasp the object, which is one of the basic functions of the robot. Although there are a lot of research in these areas, from the current technology progress in recent years, we are still facing great challenges in applying robots to do housework.

455

The increasing demand of humanoid robots, the continuous development of artificial intelligence  and hardware make the service robots move from laboratory to home in recent years, and develop from  single functional sweeping robots to multifunctional personal robots.

 

Cookid intelligent humanoid robot is born in such fast changing environment. The humanoid robot like Cookid in China is still a new thing but as people are gradually familiar with smart devices and frontier technology , there must be a broad market prospect on smart service humanoid robots.

 

 

We can see from the  robots movies that the robots usually have their own mentality to answer people’s questions, to think the right answer, to make a relative response. In fact, this is a comprehensive application of perception, cognition and behavior control. The perception is mainly based on vision, hearing and a variety of sensor information processing; The cognition is responsible for higher level semantic processing, such as reasoning, planning, Learning, etc .; The behavior control is how to control the behavior of the robot.

Currently, the humanoid robot has been able to achieve some of the functions,  although it   still in the primary stage, not particularly perfect, for ordinary people, it’s still attractive. Man-machine voice communication, through the dialogue with the robot, people can know about the weather, news, also can make joke with robot, these are some functions that can be realized at present.

Humanoid robots also have a certain body movements, their bodies can be as flexible as human beings, from head to toe, it can be rotated and stretched. What’s more, these humanoid robot with some of the functions also facilitate people’s lives, for example, video calling, taking photo, video monitoring, life reminders and so on.

The future has come, intelligent humanoid robot comes quietly, the new technology will bring endless possibilities for human life, and the world will become more and more exciting.

Hi Al

 I re-downloaded and scanned with AVG anti virus.  No problems were detected.  The web hosting service (Weebly) also scanned the files for issues before posting them.  What anti virus package are you using?

   Regards

Chewy,

Thanks!  I am having issues downloading the two zip files - the computer thinks the files have viruses.  Did you have the same issues?
