Description

  • Analog encoder pair for Tamiya Twin-Motor Gear Box (only config. C)
  • Includes two encoder PCBs, two Encoders wheels and two cables
  • Designed primarily for DFRobotShop Rover
  • 16 counts per rotation


The Encoder Pair for the Tamiya Twin Motor Gearbox allows you to add a pair of encoders to the popular Tamiya Twin-Motor Gear Box . Note that the encoders can only be used when the motors have been assembled in configuration C. The encoders were designed to be used on the DFRobotShop Rover, but can be used on any project. The encoder PCB needs to be glued (a dab of hot glue is ideal) to the gearbox, and the white encoder disc is press-fitted onto the 3mm hexagonal output shaft.

Works as expected

Product works as expected. I'm using them to add encoders to continuous rotation micro servo motors and they fit perfectly with a little hot melt glue. I had to discard the plastic encoder wheels and printed my own using address label paper to stick to the servo horns. I agree with other users that they should come with right angle headers or straight pins unsoldered. The non-standard pin wiring is also a minor pain to rework. Should have a digital output instead of analog output.

Not bad

The encoder wheel is very fragile - you can break it just by dropping it on the floor. You may need a Schmitt trigger (or a comparator) and/or some low-pass filter to get the output signal ready for a microcontroller. It's a bit too expensive for a simple circuit like that. Other than that, it works great

Works as advertised

This encoder pair is nicely built overall, I got it working with DF Rover right away. How to incorporate encoder data into your code is another story. Depending on your goals you may need some (a lot) of experimenting with the code. So, first of all, I'd suggest to buy and attach a Bluetooth Bee to the rover to monitor encoder data (and other parameters) wirelessly via a serial port. Secondly, after some of that experimenting and/or re-assembling the rover a few times you may realize that one of the encoder PCBs got loose. After one such accident I decided to glue the encoder PCBs (not the wheels) with 5 min epoxy instead of hot glue. Whatever works ;)

Fonctionne comme prévu

Le produit fonctionne comme prévu. Je les utilise pour ajouter des codeurs aux micro-servomoteurs à rotation continue et ils s’adaptent parfaitement à la colle un peu à l’état fondu. Je devais jeter les roues codeuses en plastique et imprimer les miennes avec du papier pour étiquettes d’adresse à coller aux guignols. Je conviens avec d’autres utilisateurs qu’ils devraient être livrés avec des en-têtes à angle droit ou des broches droites à dessouder. Le câblage des broches non standard est également une douleur mineure à retravailler. Devrait avoir une sortie numérique au lieu d'une sortie analogique.

Pas mal

La roue codeuse est très fragile - vous pouvez la casser simplement en la laissant tomber par terre. Vous aurez peut-être besoin d'un déclencheur de Schmitt (ou d'un comparateur) et / ou d'un filtre passe-bas pour que le signal de sortie soit prêt pour un microcontrôleur. C'est un peu trop cher pour un circuit simple comme celui-là. À part ça, ça marche très bien
