Feetech Chassis on Amazon

The two chassis I got direct from China are now available on Amazon. $15 gets your choice of beautiful aluminum chassis kit with two DC motors PLUS the coveted motor controller board which drives two motors using servo-style pulses. Essentially converts DC motors into CR servos. Mikey Likey. Mine are red, these are blue. I'll have to get blue ones too, I guess.

blue rectangular https://www.amazon.com/gp/product/B06XZC2XDV uses gutted 9g servo-style gearmotors, works fine. Heavy-duty caster seems out of place but works.

blue round https://www.amazon.com/Feetech-FT-DC-006-SMC-Aluminum-Vehicle-FT-SMC-2CH/dp/B06XXS8L1C uses Solarboticsstyle gearmotors in several different gear ratios, 48:1, 120:1 or 256:1 but the description doesn't say which. I favor the 120's myself.

There are a few Feetech offerings on Amazon as well, they look similar. There's a red round with no controller for $15 and a yellow rectangular with low-grade FS90R CR servos, I'd stay clear of those.

  • How do those motors work erco? They look like the low torque, speed demons I have on other critters.

    On the round robot? They all look alike, even with different internal gear ratios. I know exactly the too-fast types you mean, most are 48:1 and very squirrely. AsI mentioned in the OP, I much prefer 120:1 or 256:1 types.

    Prices increased from $15 each to $20/square and $18/round since I posted.

    Apparently I'm manipulating the world of robot high dollar finance.

  • Not surprised by the price increases. This brings them closer to Adafruit, and helps them absorb the high failure rates of those motors.

    They really are crappy motors, in case you didn't know!

    I saw that too. Should have ordered at $15! But my hands are pretty full and project back-up is increasing...

    Guess I'll just keep watching...
