Drumming robot

MIDI drum machine to complement live electronic music

Similar projects worth following
Robotic drummer for a concept electronic metal band. Several bands now have robot drummers and I wanted to join the fun, but with my own cyber-horror style.

For this project my goal is to learn ::ROS, create parts that look organic by using Generative Design functionality in Autodesk Inventor, get experience with modern servos and linear actuators, and finally build a robotic drummer for my neurometal band. Also see my exoskeleton.

The files are available on GitHub.

  • Getting Dynamixel Pro to work

    Valeriy Novytskyy06/26/2020 at 18:34 0 comments

    The basic test with Dynamixel Wizard on a Mac was successful, but I still can't get it to work in a Linux VM, or on the Pi.

  • Prototype Parts

    I got laser cut parts to prototype one arm, now I just need to get screws to assemble all of this, hook up actuators and servo to their driver boards, and driver boards to Raspberri Pi.

  • Robot Hot Spot

    Valeriy Novytskyy06/17/2020 at 05:15 0 comments

    Today I finally completed the setup of the Raspberri Pi as a WiFi HotSpot. Now I can connect to the robot's WiFi network and control/monitor the robot operating system running on it.

    Since I had to come up with a name for the hot spot, I am officially calling this robot "Str1ker".

    I used the solution in: http://raspberry-valley.azurewebsites.net/RaspAp-Wifi-Hotspot/ to run the hotspot.

    Unlike the countless console commands I tried before, the setup was really fast, actually worked, and give me a GUI interface for configuring the hotspot.

  • Dynamixel Servo

    Valeriy Novytskyy06/15/2020 at 18:28 0 comments

    Today the Dynamixel Pro servo arrived - thanks Robotis!

    I built ROS Melodic from source (there was no distribution for Raspbian on my PI4) but got stuck configuring it as a Wi-Fi access point so that I can connect to ROS master node running there. I'm sure that will be fixed early this week and I can proceed with hooking up servos. I also contacted someone I worked with before to make an arm prototype out of wood before ordering sheet metal parts or making investment casting molds.

  • Actuators

    Valeriy Novytskyy06/12/2020 at 06:07 0 comments

    I went pretty far with the CAD model without validating the design, so it's about time to build a prototype of one arm. Today my order of Raspberri Pi and the two linear actuators came in.

  • Leg Shocks

    Valeriy Novytskyy05/26/2020 at 01:41 0 comments

    Spent really wonderful 2 hours searching for extra-short shocks for the legs. Finally arrived at a golf cart shock on Amazon.

  • Mecanum Wheels

    Valeriy Novytskyy05/25/2020 at 19:03 0 comments

    I am going to try to put 6" mecanum wheels on this thing - thanks McMaster carr! Truly space age stuff here.

  • If it fits, it sits

    Valeriy Novytskyy05/23/2020 at 19:14 0 comments

    Haven't felt like doing CAD lately, going to take a 2-week break - but here are some renders with roughly blocked out legs next to a blocked out drum set. They will have internal spring shocks on them as well, and I am thinking whether I need to rotate the front legs or leave them fixed.

  • Shocks arrived

    Valeriy Novytskyy05/22/2020 at 01:46 0 comments

    I tried to pin down a set of shocks that I can include in the assembly, but they kept going off market. The problem is that they are extra short (for a motorcycle) and extra long (for a bike) so basically I had to order them before all other parts, just so I could depend on a specific part to include in the virtual assembly.

  • Gearbox and Adapter

    Still working to pick the gearbox and adapter for rotating the torso. Doesn't look too unsightly:

Hello! This is such a cool project, thank you for sharing your updates. The organic structured prototype parts look sooo amazing. Can't wait to see it all come together.
