What is OpenOdometry?

OpenOdometry is an open source odometry module created by FTC team Primitive Data 18219. This module has been used either in CAD, as a starting point for designing a similar odometry module, or has been built for the robot by nearly 500 teams. What is unique about OpenOdometry is that it features a design where the omni wheel used for tracking is sunk into the plate, enabling it to be fit into a 43mm wide GoBILDA channel easily with an overall width of around 40mm. In addition it has a robust design, with 5mm thick plates and the durable REV Through Bore Encoder.

How can I get access to the OpenOdometry module?

There is an access form which asks for some basic information so we can keep track of how the OpenOdometry module is being used, allowing us to continually evolve the module. After completing the form, we will email you STEP files of the CAD and a configurable Onshape link for the V3 OpenOdometry CAD. This configurable CAD file allows you to easily change aspects of the 3D-printed parts to match your printer's tolerance. In addition to providing the CAD files, we are also happy to 3D-print the parts for you if you are unable to do so and we are always available to help or answer questions.

What resources are available?
