Mechanics and Construction / Re: Robot wheel/omni Directional Wheel
« Last post by Avadon77 on November 08, 2016, 10:07:35 PM »
what are the dimensions of those wheels?

I've never used Omni's and I'm hoping I can get the following answered as well as your questions.

*What are the trade-off's with larger vs smaller rollers on the omni wheels. I see some that have a ton of tiny small wheels and others which only have 3-4 rollers. What is the pro vs con with this?

Once I build it. I thought of going to the Toronto comic on,  show it at the TorontoPropExpo. But I also thought of my old neighborhood, which in fact is the 2nd largest subsidized housing unit in Canada as I understand it. The school I had attended there I think would benefit a lot of kids by way of education and hardwork. We also have a hospital for sick kids, where my daughter will have surgery in a little over a week from now. A lot of prop-cosplay folks do that...GM

That is amazing. What will you do with the armor after you build it? Have you thought of working with kids or sharing your work with them to inspire them? That would get every high-school kid I know excited!

Mechanics and Construction / Appropriate Components???
« Last post by Kate91 on November 07, 2016, 10:41:22 PM »
I am designing a prototype product and would like to use a series of components from Little Bird Electronics in the production. (https://littlebirdelectronics.com.au)
I would need it to, once a button it tapped, initiate wheels to roll until the light sensor sensors light. Then I would need a programmer connected to the light sensor and wheels to stop the wheel movement & start a robotic motor to raise 2.5 - 4kgs, to an 80° angle.
For the same action to happen in the opposite series of events (lower the object and roll back until light sensor, on opposite side of original, can no longer sense light) would I need a different set of programming (i.e. different motors and programmers)?
I use thinking of using the “Tiny AVR Programmer” in congjunction with an "Analog Ambient Light Sensor TEMT6000" as well as the "12V Low Low noise DC Motor” is this the right set of components to be using?

Hi there,
I am a GPS RTK engineer from Tersus GNSS. Tersus GNSS is a start-up company from Switzerland who make least expensive, reliable, centimeter-level positioning accuracy GPS RTK boards for Robotics, UAVs and Engineering, etc. Our RTK boards can be integrated to other host devices or served as an independent GNSS receiver at a very affordable price.

In the past, GNSS or GPS RTK solutions were dominated by giant companies and they were extremely expensive. Tersus GNSS was found in 2014 and has a team of skillful GNSS RTK engineers and professionals. Our passion is to provide affordable, reliable and real-time centimeter-level positioning accuracy RTK solutions for drones and related users. For example, the Precis-BX316, the Multi-GNSS, Dual Frequency RTK Board with Dual Antenna for Heading Check it out.

In the meantime, we offer bundle kit with related antennas, cables which aim to make your application easy and convenient. If you are interested and want to know details of technical specifications, drop us a line to [email protected] for all Datasheets.
Electronics / Sabertooth 2x60 Not turning both motors
« Last post by Praetor on November 05, 2016, 07:48:05 PM »
I am brand new here and I have searched for my answer but to no avail. 

I am running a 2x60 on 2 wheelchair motors.  Using 2 deepcycle 6v batteries in series in R/C mode Using a Dx6e and I think the 617 Rx.

I have double checked my wiring and have run every combination possible with no luck thus far.

Only one motor will turn at any time.  It acts normal when I push the stick around as if I'm turning or going back ward.  There is nothing from the other motor or M2.  Switch servo leads in my channels same thing.  Only M1 works.  What ever motor I put on M1 works and the other doesn't.  I do have voltage at the terminals of M2 but nothing.  I've tried everything I can think of but nope.  Not happening.

Any Ideas

Pablo is a French autonomus rover using motors, sabertooth controller, GPS, odometer, compass ... The goal is to draw large drawings on the beach.
The mission is prepared before departure, the robot aims to trace the path on the sand with the help of a map, a GPS and sensors.
Electronics / Cookid Technology Release the Latest Cookid Humanoid Robot
« Last post by carloliu on November 04, 2016, 01:27:27 AM »
Cookid new release the biped walking entertainment robot---Cookid humanoid robot, all company executives  from Shenzhen Cookid Technology are very optimistic about this product, It represents the overall image of the Shenzhen Cookid Technology Co., Ltd.  Cookid’s goal is to make their robot walk into people’s family life, meanwhile, to integrate UAV, intelligent home system and other existing business effectively, it can also strengthen  Cookid robot’s entertainment  function.

Shenzhen Cookid Technology Co., Ltd started the robot R&D long time ago,  and we will continue to develop future oriented products, we has been in a unique position. The technically for robots development is very difficult, especially in the investment of funds and cost control, Cookid has only a small number of competitors in the entertainment robot. At the moment of Cookid robot’s birth, except of freedom and flexibility such as human walking, Cookid robot have strong intelligent entertainment ability as well, for example , singing, dancing , playing Kungfu, telling story and so on.

To drive the new technology wth the new products is the overall idea of COOKID. The technology is still the most important factor for COOKID robot. The robot technology is now in the development stage, we will develop the robots that can take care of patients or robots that can also be applied to the cause of education, we can cultivate English speaking robot dog, in the future, we can also make Cookid robot communicate with people freely.

As for the size of the robot market, the general manager of COOKID technology said, the robot market is a huge potential market, as long as we break the technical bottleneck and add more particle functions, it will be indispensable in our life just like smart phone.

it is possible to reduce the cost when the market demand is large. But now it seems to be a long time for the mass production of the robots. Although the market price has not yet been determined, but someone had estimated that the price of Cookid robot will be same as a senior car".

When the robot can really go into the human life as we predict that in 2050, the goal which can come true is that the robot can set up their own football team to enter the world cup to play football with real human. . Now IT technology and network technology are developing very rapidly, it is estimated that in 2010 the concept of home entertainment robots will be accepted by more people, then this industry will also have a great development
