Microbit Comparison Cutebot Pro vs Yahboom Smart car vs DF Robot Maqueens

We like the Cutebot Pro. I paid full price for it so I get nothing for recommending it. The other bots that work with Microbit are good also. Some are more expensive and some are less. We will do more comparisons in future videos. All these are programmable with MakeCode. So they are not just toys, they are learning platforms which engage kids and introduce programming, electronics and mechanical engineering. And they are Fun !

Thanks for the comparison! This helps a lot of us teachers. I especially liked the "battery fit" part.

What I want to know is: are the line following ir sensors grey scale or black and white?

[@makecodeandhardware1395]

I have not tested them , Don. Will do that this week. If I read your question correctly; "Does this follow a grey line on white in addition to following a black line on white ? " Watch this channel for the test project.

@@makecodeandhardware1395 actually will the ir sensors return the reflected amount (0 to 1024) instead of just 1 or 0. Maqueen Plus V2 will do that. Which means PID control can be used.

@@jdonwells You may have already seen this program; Don. I see in the Cutebot Pro extension a reference to gray value under 'tracking sensor' so to me this implies that with MB V2 that may be possible, PID control. I have not got that far with the new Cutebot Pro car. We are focused on remote control with BST M_Bit app and donated cell phones. Thanks for the input. Very interesting question. tinyurl.com/3fcd23h5

@@jdonwells , see my latest video, Don; for the answer. (spoiler : YES 0-255 ) But I don't know about PID control.

@@makecodeandhardware1395 I have a slide show to explain PID control. docs.google.com/presentation/d/1QdxlaT2WuEbwisWb3d1CxsuiMVr19kL6_wUgoftC0sw/edit?usp=sharing PID is something engineers actually use. It is an advanced topic. I teach at a high school so I like to push the kids.
