Making your own Kuka robot using EV3

Facebook EV3 group member Pi Ksar has shared with us a pretty neat robot arm made out of LEGO MINDSTORMS - I asked him a little bit about himself and describe his project:

Hi, I’m Pawel, 37 married, from Poland

background : electrical engineer
work : global consultant – 270 days per year in travel
hobby : modern technologies, history, traveling

Always dreaming about having own Kuka style robot. Because of flat space I cannot buy real one. So decision about building my own was made. Why Lego ? Because it’s flexible system and many spare parts available. First attempt was 2 years ago with NXT 2.0 but without luck – I need at least 6 motors to be controlled. So waiting for EV3...

...When EV3 appeared – bought a few sets.
Now available at my workshop :
-       4xEV3 unit, 16 servo motors, 8 touch sensors, Gyro, more sensors from sets
-       Lego Technic : Unimog, 4x4 RC, large buldoger and few more for parts
-       All parts IR : XL motors, remotes, servos

Current robot features :
- 6 axis movement
- Compressor and electropneumatic valve for claw installed in robot base

What I want to do soon :

Robot working like KUKA, with all smoothness. Plan is to install Gyro sensor to control claw, to keep it automatically in horizontal position. General robot is made to practice programing.

One of the application that will be possible is drink making.
To that set will come peristaltic pump (made from Lego) for liquid dosing, glass sorter….will see.

Any other ideas also welcome.

Celebrating MINDSTORMS with a Remix - Part 3

The ROBOTMAK3RS continued their celebration of the 25th Anniversary of MINDSTORMS through these Fall and Winter remix projects. Each ROBOTMAK3R was tasked with selecting one LEGO set of their choice and combining it with a MINDSTORMS set. Below are the five amazing models they came up with. Braill3 by Jerry Nicholls Braill3 is an EV3-based LEGO Braille bricks reader. This robot uses its fingertip, made from three touch switches, to read messages written using the LEGO Braille bricks and will speak out what it detected. If it sees a simple maths problem it will attempt to solve it and give the answer as well. To learn more about the process of creating this machine, read Jerry's blog . Braill3 can be viewed here . Set Review: The Braille Bricks set is well thought out. The ratios of the letters is suitable for general use and the addition of some punctuation and arithmetic operators is excellent. There is a card showing what bricks there are and their quantities, but no form of sort...

Celebrating MINDSTORMS with a Remix - Part 2

The ROBOTMAK3RS continued their celebration of the 25th Anniversary of MINDSTORMS through these summer and fall remix projects. Each ROBOTMAK3R was tasked with selecting one LEGO set of their choice and combining it with a MINDSTORMS set. Below are the five amazing models they came up with. Remote controlled material handle r by Jozua van Ravenhorst (aka Mr Jo) This remix combines the LEGO Technic Material Handler (42144) with MINDSTORMS EV3 (31313) It uses the power of pneumatic cylinders to move objects around. By using a bluetooth remote control, very precise movements can be made with this model. Touch sensors in the base chassis prevent the turret twisting the cables that go through the turntable to much. The program has several protections to prevent over pressurizing the system for each of the 3 individual pumps and valves that control the 2 booms and claws. The real version of this machine is mostly used in waste material sites to bring the material to machines that sort and...

Celebrating 25 Years of MINDSTORMS

In celebration of the 25th Anniversary of MINDSTORMS, we take a trip through history. Please also visit ROBOTMAK3RS Community every week as we highlight different projects all through 2023 in celebration of the anniversary. Some of the early history is based on the content shared by Coder Shah in our MINDSTORMS EV3 Community Group . Some of the text and links may have been edited from his original posts for consistency and clarity. 1984 - Kjeld Kirk Kristiansen watched a TV program called "Talking Turtle," where MIT professor Seymour Papert demonstrated how children could control robot "turtles" using LOGO, a programming language he developed. 1988 - The collaboration between MIT and LEGO resulted in LEGO TC Logo in 1988, which allowed students to control LEGO models using computer commands. The video shows Papert demonstrating TC Logo. 1990 - LEGO TC Logo was hampered since the robots you built had to be tethered to a personal computer. LEGO and MIT...
