Ozobot Bit (and Evo)

I’m working through an evaluation of the Ozobot Bit and the Ozobot Evo. I’ve had these for some time (since 2016) and I’ve tried to start some Ozobot themed races. The information on the Ozobot Bit and the Ozobot Evo is all online, and I don’t feel that there is a central place that a text-based learner can go to find the information. What I’m going to spend some time on is a navigation around the Ozobot Bit, then the Ozobot Evo, admittedly with some repetition.

So we start with the Ozobot Bit.

If I recall correctly, first there was the Ozobot Bit 1.0 then there was the Ozobot Bit 2.0 then there was the Evo.

The Ozobot Bit provides some great, core capabilities, and has a lower price point than the Ozobot Evo.

REVIEW: OZOBOT BIT 2.0

Instant Engagement for All Ages
Turn the Ozobot Bit on, calibrate it, and set it on a line of any color. If the line is wide enough (just about 1/4″ I’d say) the Bit will start moving on the line, and its LEDs will glow in the color of the line that it is following. Kinders can ooh and aah over it.

Color Based Programming Language
What the Ozobot introduces that I haven’t seen elsewhere is a color based language. Communication in pictures, shapes, sounds, written symbols, have been around for a long time, but I don’t think I’d heard of a color-sequence based language before. I suppose some IQ test may have included pictures of color sequences and sample “what next” multiple-choice questions.

Color sequences that represent instructions such as “timer”, “go fast”, “tornado” are pre-programmed in 2-4 colors. Blue, red, green and black.

Note: Variations in color instructions. I have seen conflicting instructions for the color sequences, but I think this may have been due to a change from the early instruction set.  I will test the instruction set at this location and record the behaviors in a video in this post.
