The Challenge was to use two motors and two servos to make some sort of dancing robot arms

Dancing Arms ~ with Sophie Hankin

We decided to use the accelerometer in two RP2040 and pair it to our servo motors on an axis to have the arms respond to the motion of the boards.

<aside> 💡 Now we have our idea, what do we need?

Components to get started

• Arduino RP2040 Nano
• Arduino Nano Motor Carrier
• 3.7 V Battery
• Material for the body and markers to decorate
• Laser Cutter

<aside> 💻 Approach to coding

Challenge is figuring out how to make the servo motor move, then access the accelerometer. Next combine the two.

import time
from motorController import *
from lsm6dsox import LSM6DSOX

from machine import Pin, I2C
lsm = LSM6DSOX(I2C(0, scl=Pin(13), sda=Pin(12)))

board = NanoMotorBoard()
print("reboot")
board.reboot()
time.sleep_ms(500)

servos = []

for i in range(4):
    servos.append(Servo(i))

#if (!PMIC.enableBoostMode()):
#    print("Error enabling Boost Mode");
while True:
    accel = lsm.read_accel()
    angle = accel[2]*180
    for servo in servos:
        reply = servo.setAngle(angle)
        print("Servos position %d" % i)
    time.sleep_ms(200)

    # Keep active the communication between MKR board & MKR Motor Carrier
    # Ping the SAMD11
    board.ping()
    time.sleep_ms(50)

Next we need to figure out the design🤔…

To Nolop we went and cut out some scrap material we found in an attempt to make a humanoid robot

After some successful tests the design was coming together and we laser cut some small robotic arms
