It is based around fours motors, control by a Micro:Bit, via L298N based motor controller/shield. Batteries power, 8 AAs, the motors and a Lithium powerbank to power the Micro:Bit - all included.
More information about the technical details and example software can be found on their site https://www.cbis.education/robotic-car-kit# including further details on the L298N based motor controller/shield, which I found useful for programming it.
I have experimented briefly with programming it in Python (micropython), getting it to it move forward, backward; to the right and left, using the Mu editor.
The code is shown below for those who want to try it:
from microbit import *
def forward(n):
pin13.write_digital(1)
pin16.write_digital(1)
sleep(n)
def backward(n):
pin14.write_digital(1)
pin15.write_digital(1)
sleep(n)
def stopit(n):
pin13.write_digital(0)
pin14.write_digital(0)
pin15.write_digital(0)
pin16.write_digital(0)
sleep(n)
def spinLeft(n):
pin13.write_digital(1)
pin15.write_digital(1)
sleep(n)
def spinRight(n):
pin14.write_digital(1)
pin16.write_digital(1)
sleep(n)
while True:
forward(500)
stopit(1000)
backward(500)
stopit(1000)
spinRight(1000)
stopit(1000)
spinLeft(1000)
stopit(1000)
This thing is quick. I like the feel of it, you pick it up and it doesn't feel like it is going to fall apart; because it comes all assembled - including batteries, it is ready to go. I look forward to trying some more ideas on it.
