SDS MK4i Swerve Modules

AndyMark is proud to offer the most popular swerve drive solution on the market today. AndyMark is more than just a passthrough distributer we are offering a bunch of value add features including:

• We are a one stop shop where you can buy the modules, motors, encoders all in one place on one order.
  • SDS Modules are even valid for use with PDVs!
• We are offering the option to assemble the modules for you so you can hit the ground running
  • CANcoders shipping with the assembled version include pre-soldered wires for a true plug and play experience.

The MK4i module inverts the motors on an MK4 module to a lower position where they are out of the way and better protected. Overall height and center of gravity are therefore lower. The MK4i module also moves the wheel further into the corner of the chassis for a wider wheelbase which results in a more stable robot. Because the wheel is moved into an area the frame would typically occupy, the MK4i includes a secondary plate to properly box in the chassis.

Other Highlights of the MK4i module include:

• On-axis steering encoder (zero backlash, module can be disassembled/reassembled without resetting encoder offset)
• All plates made out of 7075-T6 aluminum
• All steel gears
• All moving parts are protected under top plate
• Includes secondary plate to box in frame
• 10-32 mounting holes on main plate for other robot subsystems
• Encoder guard to protect the steering encoder
• Same frame-to-floor height as previous Swerve Drive Specialties modules
• Same L1 - L3 drive ratios as the MK4 module
• No 3D printed parts
• Cable-tie “nubs” keeps cable-ties in place
• Bottom and top mounted chassis options
• Includes wheel tread cut-to-length, drilled, and pre-installed on wheel
• Includes all hardware, including hardware to mount module to robot
  • As of July 2023 mounting hardware is #10-32, this change is reflected by an "a" in the part number.
  • As of December 2023 Modules use all "V3" components The part numbers for these modules end in a "b". See assembly guide for details

NEO V1.1, Neo Vortex, Falcon 500, and Kraken X60 motors are compatible with the MK4 module. CIM motors are not compatible with the MK4 due to their larger diameter. The MK4 module is available with the appropriate pinion kit for any of the above motors.
