This project was created on 07/21/2020 and last updated 5 months ago.

Description

Janus Jr was developed in the Arduino IDE. It's using the SimpleFOC Arduino library for position control of the brushless motors. The ESP32 hosts a HMI which allows a user to move the end effector in the plane. The correct angular positions of the motors is calculated with the inverse kinematic model of the robot. You will be able to find everything about this robot on Github: https://github.com/byDagor/Five_Bar_Parallel_Robot-Janus_Jr

it is using bldc motors of what type? and also what position sensor are you using? more details on this project would be great. It would make a nice drawbot

  Are you sure? yes | no

I will post more details in the following days.

Silly question: why are these called "five-bar" linkages when all I ever see them with is four bars?

  Are you sure? yes | no

David Gonzalez wrote 07/22/2020 at 21:28 • point

Because the distance between the motors is considered as a bar. So you have: a "fixed bar" between motors, two bars coupled directly to the motors and two bars coupled to the previously mentioned bars. :)

  Are you sure? yes | no
