Using Spike Prime acceleration data
Skookumjim posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
A small project has been to try to use the Spike Prime acceleration data and Newton’s Laws of Motion to calculate distance moved by a vehicle. The upshot of working through this has been: . that the Lego documentation is woefully lacking. ..it is not at all clear what the units are although given the the z acceleration is of the order of 989 I imagine that to be gravity in cm/s/s. . even though the hub is at rest it reports small accelerations on x and y. . applying the code ... integrating acceleration over time... the results are inconsistent even at standstill.... more so under movement. It is possible that there is a coding error but unlikely (famous last words!) So.... any ideas gratefully received! Thanks -
[MINDSTORMS] LEGO Mindstorms and Fischertechnik
fotoopa posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Connection Lego and Fischertechnik. By combining both systems we can enjoy their advantages. The data and command exchange occurs on 2 levels. There is a serial duplex connection via the hubE and the DE0-Nano_Soc board. On the other hand, the data lines of the other hubs are also read by the board. The latter can thereby process data in real time and without interaction of the running software. This data can mainly be used by the TXT Controller to display the results on the PC screen. Motor speed, position, sensor color information, distance information and pressure can all be read out. From the Lego side there is no need to write a program. The DE0 board simply listens in real time. The DE0 board responds very quickly ( only a few usec). The connection is via 115200 baud but can be much faster if needed. I now need to work out some protocols to build a large application. Lego-Fischertechnik by Frans, on Flickr With the DE0 board, I have up to 120 inputs available. I can now use those to send to the lego hub and process them there. Commands can also be sent from the lego hub to the DE0 board and so on to the FT Controller. The possibilities are immense. I hope to present a larger project a little later. On the Fischertechnik side, I have a lot of outputs. Now I can already connect 16 motors, 16 servos, various digital outputs, etc. Frans -
On Wednesday 26 October ("Herfstvakantie Zuid"), Sioux Technologies organizes a 2 hour programming workshop in Eindhoven (NL) for kids in the age of 7 and older. As a tech company, we want to promote technique for children and Lego Spike is a great way to do this. And it is complete free of charge, we will even take care of drinks and food. Please note that the workshop is in Dutch as is the invitation. More information can be found here: https://www.sioux.eu/events/all-events/hot-or-not-the-next-generation-workshop/. You can also use this link for subscribing your kids. Questions? Just leave a message. Looking forward to welcome you and your children at Sioux. Hans Odenthal -
Controlling the Rough Terrain Crane
Skookumjim posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I have for a while wondered about using robotic components to automate/control the Lego Rough Terrain Crane ... this has now happened using the Mindstorms Robot Inventor hub with 5 medium stepper motors and a distance sensor ....while keeping the original power functions large motor to avoid further destruction of the original model. One motor switches turntable rotation, another switches the drive from turntable to jib while a third switches power to the original motor. Two further motors switch the six way gear selector for hook and jib. the distance sensor is used to limit turntable rotation to accommodate the relatively short cable lengths. The resulting construction works well.... the crane can both remote controlled and programmed. https://www.dropbox.com/sh/82vqyjvd2zledp0/AAA736uPmlzo9hL-sIWdGS8la?dl=0 -

I accidentally found this video and it's a very impressive example of what could be done with Lego: -
The fragmentation and its consequences
astral brick posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Summarizing: - WeDo 2.0 - Spike Prime - Mindstorms Ev3 I believe that, since their introduction, automation and then coding were supposed to represent the natural evolution of Technic,however they ended to be confined in the educational niche. Moreover, wouldn't have been better, on a marketing level, to avoid the fragmentation in three themes? I understand that there are different ages and costs but I think that Lego could have stuck with only one sub-brand, whatever it was, then proceeding to diversify. A single sub-brand would have increased the exposure, hence the sales. Confusing marketing, wasted opportunities. -
Entry for CCC Miscellanous For many years the Synneora Rock was dwelled by a lone monk Athios, who had decided to spend the rest of his life meditating and devoting himself to God. When Athios passed away, the rock soon became the center of the country's religious life. Hundreds of pilgrims and the nearby villages inhabitants volunteered to help building a new chapel for the memory of Athios - a man of Faith and Sacrifice. Thea main sources of inspiration were Greek monasteries of Meteora, Zhangjiajie rocks (China) and Ha long Bay in Vietnam. I came across an article about Ha Long Bay and that was when I promised myself to try a new "tilted rock" technique, attaching part of the layout diagonally. I recommend it to hardcore-builders. It was the most extreme rock that I've ever made and that is because it is not really a strong construction and once you put a segment to place, nothing can be done... :) Well, it was fun.
