  • GitHub project setup

  • This week I setup project management Kanban board on GitHub:https://github.com/01binary/drummingrobot/projects/1Last sprint I had a lot of trouble finding shock absorbers for the arms and the torso. Today I finally found RC car drive links that I can...
  • UBC student prototype

  • This picture shows my first metal arm (three years old?, center left), two of my wood robot arms (from a year ago), and the prototype UBC student engineers just delivered. It runs a beaglebone black and has two identical sections. The idea is that three...
  • Numa: 18 DoF Mech Warfare Quad

  • Hardware details4DoF per leg 16 AX-12A servos in the legs, 2 AX-12A servos for the camera/gun turret Axon MCU Tristate buffer allows Axon to control the Dynamixel servos. Can use either Xbee communication, or serial port communication 11.1 V LiPo battery...
  • Hardware selection

  • Specification expected linear speed for a 40mm wheeled robot -> [10mm/s; 1m/s] transformed into wheel rotational speed -> [XXRPM; XXRPM] To match spec, we need to paid attention motor's type. For our application, three type of motor would have been OK...
  • Firmware design

  • First, we want an using firmware with the minimum of features: bring the food from the plate to the mouth at the user’s mouth clear out the plate save the mouth position Our strategy is to learn every position that the robot should reach during the meal...
  • LibreServo

  • This project was born as a necessity of mine to build a biped robot with intelligent servos to be able to “feel the muscles” to walk more human like. In the past we had OpenServo, and I think this project inherits something from it, but...
  • Serial Communication on a Hacky Afternoon

  • This might be one of those things we probably did on a lazy afternoon. Or evening. I don't remember. Coming up with ideas when drowsy... Half asleep, half awake. When we got to our senses, we realised had a bunch of code that did the job well, but didn't...
  • On the road again!

  • Tenacity is back on the road!(carpet), fresh from what turned out to be an almost 3 month(-ish) refit.  A good bit of consulting work came barrelling out of nowhere right after the start of the New Year, so I've spent most of the past couple months...
  • Detecting carpet

  • I have started working on autonomously detecting surface unsuitable for a vacuum suction cups. Bellow is a video of robot walking straight until it fails to grip on a carpet and then turns back:As you can see at the end of the video robot fails to grip...
  • Technology readiness level 3

  • This week naminukas reached technology readiness level 3. I was controlling robot with one hand and filming with the other so video is not award winning but it is the first time robot demonstrates all 3 operating modes (walking, driving, climbing):There...
  • New rotation motor & source on GitHub

  • Over the past few weeks I found another, cheaper servo that's still strong enough to rotate the arm:https://www.gobilda.com/5202-series-yellow-jacket-planetary-gear-motor-188-1-ratio-30-rpm-3-3-5v-encoder/It has a built-in encoder, 100N of force,...
  • New Project: Phoebe TurtleBot

  • While my understanding of the open source Robot Operating System is still far from complete, I feel like I’m far enough along to build a robot to run ROS. Doing so would help cement the concepts covered so far and serve as an anchor to help...
