Re: Lego-Fischertechnik.

The WeDo 2.0 motor being detected and used by the Spike: Believe me, they are all compatible. I own them all :-) Surely a photo like this is convincing. This means that this extension cable would fit on the Mindstorms 51515 hub : https://www.toypro.com/nl/product/7355/electrisch-verbindingskabel-mi...

Re: Lego-Fischertechnik.

How do you change the sensor mode then? I know some sensors have something like a "report everything" mode which may be what the spike enables by default. But not all sensors support that.

Re: Lego-Fischertechnik.

Please try to read e.g. a distance or raw RGB color information from the color sensor. This will imho only work if you change mode. The old motors work on the new controllers. Actually the motors sold with e.g. the city hub in the batmobile IS one of the old wedo2.0 motors. I have read those too an...

Re: Lego-Fischertechnik.

You cannot do much with the sensors if you only listen to them. All the sensors support many "modes" like e.g. the color sensor that can either sense colors or ambient brightness or even distances and much more. The motors can e.g. sense speed, torque, angles and much more. But the controller needs...

Re: Lego-Fischertechnik.

You don't need anything between the TXT and the LEGO controllers for this. The TXT is able to directly interface to bascially all the LEGO controllers, either via USB (e.g. to the Spike Hubs) or via Bluetooth (to the Technic and City Hubs). And also all older LEGO controllers like the Boost, WeDo 2...

Lego-Fischertechnik.

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. ...

Re: A trampoline project

I'm going to close this topic now. Robots should continue to help me for the new projects from now on. Intention is to make FT and Lego work together. At least the software is similar. Linking both groups will be fine with the help of extra 3D printed blocks. If there are results I will make a new t...

Re: A trampoline project

Why are there six wires, shouldn't four suffice, as GND and V+ can be shared between the two sensors? And have you considered a design where the wheel is enclosed within the building block to make it more compact? Yes 4 wires are sufficient. There is a practical reason why I use 6 wires anyway. All...

Re: A trampoline project

I have some delay to make a video of the trampolines. The reason is that I have to add 2 extra motors at the top of the input module. The balls need to fall slightly off the center of the first trampoline to take a stable direction. I need to be able to adjust the X and Y direction of the falling ba...

Re: A trampoline project

Thanks Rubem! Looks great! it's always a pleasure to follow your posts and see your progress. Will you post a video at some point? Yes a video I would love to make. Currently the test program is ready to set all trampolines. The next task is to measure all the positions of the trampolines for the 9 ...

Re: A trampoline project

Complete setup of 4 trampoline modules and 9 Funnel capture units. The input of the balls is still done manually at the top left. Via an XS motor, a ball is passed by the program. At the exit where the balls come down there is a hall detector placed. This signal can be used to finish further action ...

Re: A trampoline project

First test program to control and adjust already 3 trampolines. The settings to go via 2 trampolines to an output funnel with the balls is not easy. With the right adjustments I managed to get most of the shots correct. Now I can make the position optimization of the funnels. Especially driving shar...

Re: A trampoline project

The first trampoline module is assembled and tested. This module contains 2 XM motors each with a quadrature encoder that has 32 pulses per worm revolution. The base rotation consists of a gear of 58 Teeth. This makes 58x32 = 1856 pulses per full revolution available. This corresponds to a rotation ...

Re: A trampoline project

Thank you Rubem! I am now performing tests to determine the proper drop height of the balls and the position of the trampolines. The rebound of the balls is never really even, which makes it difficult to move from one trampoline to several others. I have now made an dual additional adjustable guide ...

A trampoline project

I have started a new project with trampolines. Four modules are foreseen. Each trampoline is set up in a rotating position. The whole thing is also set up on a turntable. The hinge point of the trampoline lies exactly in the trampoline surface. Because of this, there is no shifting of the center poi...
