Superb review, Jim!

The app has been released now: https://play.google.com/store/apps/details?id=com.lego.retail.mindstorms

Hey Jim, I received the set directly from LEGO to film an unboxing video as well as creating other videos. I am part of the ROBOTMAK3RS family and we are allowed to start posting content as of October 8th, 2020 - 8am CET. A lot of other videos are being published here as well. I am looking forward to your review! I don't have the technic hub. The technology used is almost the same as the SPIKE Prime set.

Next week, October 15th, the new LEGO MINDSTORMS 51515 Robot Inventor Kit is going to launch. Curious about what’s in the box? I had the opportunity to unbox a set to give you already a glimpse of all the new goodies. Check it out ! #mindstorms #robotinventor #robotmak3rs

Hello fellow Mindstormers! It's been a while, but I'm back with a new robot. Within our local Robot Community we decied to start some Lockdown Challenges since we are not able to meetup online. Our first challenge was to create a robot that doesn't fall from a table. Pretty easy, right? Here is my attempt: If you want to try it yourself, post your version in the comments below ! Regards, Brickobot

Lovely robot. Also an interesting technique to use studded parts to connect the Technic beams to each other. Any reason why you do this?

This is a one day build? Wow!!

Probably between 40 and 60k, some are set, but the biggest bulk comes from bricklink and LUGBULKs

How on earth do you build that compact

Amazing build! Will you be sharing the LDD?

Beautiful! How is the sideways stability?

I like the studfull cab a lot more that the studless. Blends in perfectly with the red outtriggers. Beautiful work!!

Stunning model, beautiful mechanisms, love every part of it!

Such a masterpiece! Well done Effe!

Love it!

It should be possible: https://play.google.com/store/search?q=EV3&c=apps&hl=nl_BE Although, I can't find any source code.

Very good replica of the topline cabine!

Hasn't your EV3 been shipped yet? Where did you buy it in Belgium?

Combine python & EV3! https://github.com/topikachu/python-ev3

You can download the instructions for the core models as PDFs from here. http://robotsquare.c...44-instruction/

Yes, the intention of this mechanism was to put a can on top of a shelf. The arm will open when the you place the can back on a higher platform than were you have picked it up from. I have tested this myself and it works without a problem.

I have no idea what you are trying to do, but it seems that a subroutine is a valid option if both motors have to run at the same time. You might consider reading this: http://bricxcc.sourc...XC_tutorial.pdf Or look at the mindboards forum for more people to help you.

Cute SkidSteer! Good job!

Marvelous

I'm not sure if I understand your question correctly, but from what I see in your program you are trying to control both motors at the same time. I have made 2 simple programs for you. I will explain them more in detail. task main () { RotateMotor(OUT_BC, 75, 360); RotateMotor(OUT_BC, 75, -360); } You had already found the 'RotateMotor' function, so I guess you know what it does. You're program might work, but it is not very efficient. You can declare 1 or 2 output motors in the function. As stated in the program, I control motor B and motor C at the same time. you could also use motor A and motor B or... It also works with only one motor for output of course. RotateMotor(OUT_A, 75, 360) Let's now move on to the same program with synched motors. task main () { RotateMotorEx(OUT_BC, 75, 360, 0, true, true); RotateMotorEx(OUT_BC, 75, -360, 0, true, true); } Let me explain the different functions between brackets: OUT_BC: defines the motors that you are using 75 : motor speed (number between 0 & 100) 360: degrees that you want to turn 0: the difference between motors, but if you use a 2 wheeled robot, this should be set to 0. If you for example set this value to 50, one motor will turn 180 degrees and the other one 360. 'true': tells the motors that they should be synced (basically this should always be set to 'true') 'true': tells the motors to stop at the end of the program. If set to 'false' the motors will not stop at the same time. You should always set this to 'true' to have a accurate robot. I hope this helped you out. And I hope my explanation is understandable. If you have more questions, just ask :)
