Real-time Motion Planning with CollisionIK
Log from Crash
Motivation One major barrier to a fluid creative workflow with robots is the often stilted sense-think-act loop. Every time through the loop the robot first gathers information about the environment, crunches the numbers to generate a plan, and then...

Physics Model
Log from 2021 HDP Dream Team: EJA
To predict how our robot may perform in the real environment, a physics model would be useful to understand the forces at play. The calculated results serve as data points that can be verified experimentally to see how they differ in the real world....

Initial Work
Log from Health Maintenance Robot
I uploaded a video where I ramble about my intentions of building this robot.I mention some of the parts I plan to use with the robot and give a general overview of my plans.Here are a couple of photos of the two tread sections I've built so far.The...

Autonomously locating targets
Log from Firefly — A Low-Cost Flying Robot to Save Lives
The third component of Firefly's algorithmic layer deals with the problem of autonomously locating a target—like a trapped victim after a disaster or the source of a fire in a burning building—by combining multiple different sensory inputs. The problem...

Validación de la selección de motores
Log from Desarollo de Un Robot Hexapodo-UVG MT3005
Como podemos validar nuestra seleccion de actuadores? Para poder validar la seleccion de nuestros Servo Motores tenemos que analizar la estructura desde un punto de vista estatico. El criterio para nuestra seleccion debe de esta basado en el torque minimo...

Efficient Sonar Gridmaps in Python
Log from PyRover
One foundational challenge for a lot of hobby robotics is navigation and localisation. We can access cheap sensors in the form of IR and sonar, which give distances to solid objects. We can use IMU's and wheel encoders to estimate distance and direction...

Absolute encoder shootout
Log from Drumming robot
The winner for this specific application (measuring angles on robot arms for inverse kinematics) is the 6mm hollow D-shaft potentiometer from P3 America: https://p3america.com/np24hs-r10k-l2-d5/ https://p3america.com/rh24pc-e-r10k-l2-d5/ Despite the...

Proximity sensors working!
Log from 1 Inch Rover
So some progress, parts showed up and I have them working on the bread board. I got the TCA9548A and VCNL4010 break out boards from Adafuit. These will be the basis of the robot sensor system.You can see the 3 VCNL4010's on the right there. Currently,...

IMU processing (part 1)
Log from Build your own TurtleBot 3 backbone
Hardware integration IMU used for this project is the MiniIMU-v2 from Pololu, it incorporates several chips that offers 9 degrees of freedom, allowing a complete attitude estimation. magnetometers, LSM303, 30Hz Output Data Rate, 1.3gauss scaleaccelerometers,...

Solution #2: Theory and Implementation of Graph SLAM
Log from Multi-Domain Depth AI Usecases on the Edge
First, I have analyzed the computation of Graph SLAM step by step and then implemented the algorithm efficiently.Assume a robot in the 2D world, tries to move 10 units to the right from x to x'. Due to motion uncertainty, x' = x + 10 may not hold, but...

Subsystem - Mobile base
Log from [2021] Aina - Humanoid plataform ROS robot
Hi guys, in this log I intend to explain a little bit how the mobile platform works, so as usual this subsystem will be divided into two main topics: hardware and software, but before that lets see a video! Software One of the main concepts in...

Step 10. All Hardware and Software Updated: UV Rerflector & OpenCV
Log from UV Sanitizing Autonomous Robot
This is a nice project and I have updated it. Below you can see the particular goals: Developing a reflector to concentrate the energy of UV lamp on an object: backless stool;Making the Cascade Classifier of a backless stool u other object; andUsing...

Motor Sizing & Wheel Selection
Log from LabRATory Telepresence Robot
Hello All!In this post I am hoping to showcase some of the design work that goes into motor selection. If you are curious about this process, I highly recommend the free resources available at the California Mechatronics Center . This company...

Pixelium Illuminatus
Log from Cardware
And other arcane mutterings. After meeting a dead-end in AIMos with the image recognition based on pixels, I realised I'd have to find a way to either make them triangular to use Euclidean math on them, or, find a way to make Euclidean math work on polygons...

Project Log 2: The artificial skeleton.
Log from DIY Mech/Exoskeleton suit.
Monday 22:25, 28/11/2022 - I'm procrastinating One thing that I forgot to talk about on the previous project logs is that the structure where the entire machine sustains itself is as important as the controls, the energy source and the actuators. And...
