I recently 3d printed two hailfire droid wheels, does someone have a list of items and parts I can use as the bearings? I cant seem to find anything but gbc balls. -
Thanks! Did not know that existed in pybricks, I will try it out!
-
is there a way to connect a powered up technic hub to another powered up technic hub? i would like to make a remote control using one powered up hub and control it using another ( I have only 1 remote control and 4 technic hubs along with a bunch of sensors and motors)
-
For some reason my servos arnt working properly and randomly go to extreme positions sometimes, still not sure what is the cause but it happens when using the battery or DC power
-
Can I power the shield with this? its an AC-DC power converter and is pretty old, works pretty well and when tested with a multimeter its accurate It can power the circuits and servos pretty well I will purchase some voltage regulators and capacitors too to keep the voltage stable-ish Here are some images of the current build :D
-
Alright, thanks! technically all I need is a plug that has DC power, cut it open and then solder it to PH2.0, right?
-
I'm getting the shield with a PH2.0 port. I meant is there a USB-A to PH2.0 plug that will work for the shield instead of having to use wall power? And for the wall plug - PH2.0 can I just splice a normal wire to PH2.0 or do I need some special adapter, do they sell wall plugs to PH2.0 so I can program my robot continuously or how would I make one?
-
Do you think I can connect the DC to USB-A instead? And is there a British plug version for the connector?
-
I just received my 10 Geekservos and borrowed an Arduino kit, I'm not sure how to control it yet (after I figure out C++ language ill try) I have a raspberry pi too, will purchase the Arduino Nano soon.
-
Alright, thanks for your help! Ill try and figure out the Arduino soon, just got the 10 motors and will be testing them out with one Arduino I already have.
-
Thanks for the wire, I will think about it For your code, did you use some program to predict the motors to move at some speed and angle repeatedly with many variables? about the gears, my motors are geared 1.4:1 and is there a gearing function in C+ for servos? when setting servos to certain variables, can you add something like [14:40] signifying 14 tooth gear to 40 tooth gear? Also does the board come with a remote control receiver or Bluetooth so that you can send signals from a device?
-
Do you think getting two shields (one PH2.0 and one DC) is worth it then? How long does the battery last on average and is it possible to create a PH2.0 port to wall socket cable? Also, can you control and/or send signals to the Arduino for remote control through the shield? Eg Bluetooth or RF signals (or program wirelessly through Bluetooth like the ev3) Thanks for the code, I'll try to figure it out, I have never used inverse kinematics before so it might be a bit difficult, also when using Arduino/c to code, is there gearing for motors?
-
About this, do I get the PH2.0 connector or the DC connector? And for the wires do I need to power the Arduino itself or does the shield power the Arduino? Also about the video how did you figure out the maths for inverse kinematics, and do you have a video or diagram to help?
-
alright ill use a lipo then, i could get a power bank off Xiaomi but I am not sure how it will last, is there a power cable that I can use from the wall power to the Arduino when testing? instead of using the lipo and having to charge and discharge it constantly. this video btw
-
im buying everything except the batteries and charger since I'm not sure how I like the lipos but if I complete the robot ill switch to them. also for your robot, how did you get the arm at the end to be so precise and travel along a flat line so perfectly? its amazing
-
my first time using arduino and geekservo, not much experience in C but have experience with python I'm planning on making a 8dof rc walker with an arduino that can object detect with 2 ultrasonic sensors /distance sensors, 2 motors per leg hopefully can work made prototype out of only lego and coded with pybricks
-
i found that picture in an online singapore shop i think google searching "rc motor to lego axle adapter" works
-
danggg that is amazing! planning on creating a version based on your 12 dof dog :D were geekservo motors too underpowered for this? also how much N/M of torque do they have
-
very nice model! good job and love the amount of motors crammed into the build lol
-
probably with something like this? some kind of adapter people sell got any suggestions for brands of motors? (1/10th or 1/8th scale)
-
are there any around 100mm tires? that can fit lego maybe?
-
ooh thanks, i dont mind gearing down, i can use metal axles, metal gears/pulleys, geared wheel hubs... etc i dont mind super high rpm so long as i have good control of the torque and good speed to go zooming across flatter terrain
-
i have been wanting to create a brushless crawler/buggy to go off-roading for a while from what i can tell it probably would be either 1/8th scale or 1/10th scale and I need a sensored brushless motor an esc for the brushless motor a receiver and controller for a servo and esc and battery. does anyone have any suggestions? I don't want to use too much gearing if possible and have a single motor
-
ah thats a good solutution
-
pretty cool gearbox design i wonder how much torque it can take though and is there more resistance to shifting when there is load?
