Great video, I love the modular design so you could update the front, rear and side panels to incorporate other sensors/components as and when required.
This is great, looking forward to the videos! And about the wired connection to a rotating device I was wondering about it myself, looking at surveyor's total station devices which also use lidar in a rotating scope. And after a bit of searching I came upon a connector called a Slip Ring.
You sure have cool projects. I will be watching your build but likely will not build myself. I like to see how much I can do on a shoestring budget. Thanks for the video and look forward to seeing the project come together.
batteries are really expensive to get shipped from pimoroni these days. I tried ordering one (2000mAhr) in august to a uk adress, and they wanted a postage premium of over £41. I ended up buying 2 the same capacity from amazon including shipping for less than half the price of their shipping. I did have to reverse the jst connector pins, though so it is worth mentioning to check that the polarity is correct. I like your vid and robot. my own robot is using a pi zero w with "lego compatible" motors, pimoroni explorer hat, pi camera, and a lego frame (no 3d printer). I have 2 TOF sensors connected, one for the body, and one for the "head", but one went on the blink, so I had to order another one. I'm working on hardware for muliple switch sensors, but it is slow. I'm interested to see how your testing with ROS2 goes. currently I just use python, but I keep the code on my file server. that way I reduce the writes to the sdcard.
I know this videos are like a year old but so far is the most interesting and easy to follow tutorial for start learning ROS2... I have a question, Will be possible to use the Inventor Hat Mini instead of the explorer one?
Hi Kevîn. Nice project, will be interested in building one. Can you give us more details about the exact type of the n20 motors ? I just now checked the pimoroni site and see that there are different models. will the all fit ? Keep your cool stuff going !
It's a work in progress, so currently, the motors are not wired up yet. I want to collect odometry information from the wheels/motors, however, in the first iteration, they will just be simple motors. I've a bunch of 150rpm 6v N20 motors, so that's what I'm using first.
ROS2 seems to have more modest hardware requirements compared to ROS1.. I wonder why a platform capable of running ROS1 can't run ROS2! For example the $500 MIKRIK uses ROS1 on the Orange Pi Zero3 and ROS2 for the for processing (LattePanda Delta 3, Intel NUC, or NVIDIA Jetson Nano, etc). And why don't drones use ROS? From what I've seen, they typically use either PX4 or ArduPilot.. maybe MavRos. Is ROS harder to configure and build on small embedded hardware? I'd like to make a very simple demo, using a BLDC motor and hall-effect sensors for the commutation feedback. Could ROS be used for this?
