SourceRoboticsToolbox 1.2

Python module for Spectral BLDC motor controllers

Source Robotics Toolbox

How to install?

pip install SourceRoboticsToolbox

How to use?

This lib was created to simplify the control of your robot with Source robotic line of motor drivers.

Pairing it the with Spectral-BLDC lib allows you to write extremely simple yet capable code for robotic control.

Some features it offers:

• Sector homing

• Robot joint mastering/calibration

• Converting encoder ticks to joint position and speed

• Converting joint position and speed to encoder ticks

• Radian 2 degreee, degree 2 radian position and speed manipulation

Skeleton sketch

import SourceRoboticsToolbox

import time



# This is represents encoder ticks where your joint should be at 0 rad

# Usually you know that joint position from your robots DH table / kinematic diagram

Master_position = 14000 

Joint_reduction_ratio = 6 # Joint has reduction ratio of 6:1



Joint = SourceRoboticsToolbox.Joint(encoder_resolution = 14,

                                    master_position=Master_position,

                                    gear_ratio = Joint_reduction_ratio,

                                    offset = 0, #Change If your motor is not at 0 rad at master position 

                                    dir = 0) # Change joint direction



current_motor_encoder_position = 10000 #This emulates the data you would get from your motor encoder

# Init flag; used to run .determine_sector once

Intial = 0



while True:



    # This will give you Joint position in radians 

    # NOTE that joint position is value after the gear reduction of your actuator

    position_values =  Joint.get_joint_position(current_motor_encoder_position)

    print(position_values)



    # This will perform sector homing and determine the sector motor is in

    if Intial ==0 :

        Intial = 1

        Joint.determine_sector(current_motor_encoder_position)



    time.sleep(0.5)
