I've been working on this mecanum drive platform for the past couple months. Currently I'm using it with my raspberry pi as a remote controllable mecanum platform but that will change once I add some sensors to it.
Video of the platform driving around:
Code related to the project can be found on my github account:
Please let me know if you are building one and need any help.
- raspberry pi
- mini breakout bread board, with pi cobbler
- 4x Continuous servos http://www.adafruit.com/products/154
- adafruit pwm controller http://www.adafruit.com/products/815
- Mini DC/DC Step-Down Converter http://www.adafruit.com/products/1065
- 2x lithium polymer batteries http://www.adafruit.com/products/328
- JST female connectors
- a LiPoly charger
mecanum roller and hub hardware
- 28x R3-2RS bearings http://www.vxb.com/page/bearings/PROD/kit715 http://www.thebigbearingstore.com/servlet/the-996/R3-dsh-2RS-R3-dsh-ZZ-Radial-Ball/Detail
- 56x 3/16" ID washers
- 28x Socket cap screws 10-24 Thread, 7/8" Length, McMaster #91251A246
- 28x Lock nut, Hex Locknut, 10-24 Thread Size, McMaster #90631A011
- 4x round servo arms, ( mine were laying around and came with other R/C servos, will try to find a source for this )
- 1 can on spray on Plasti Dip ( for a higher friction on the rollers )
- print 28 of
mecanum_wheel_nut.STLand 28 of
mecanum_wheel_bolt.STL, I'll be calling these rollers from here on out.
- can be printed in ABS or PLA
- I had to print about 14 at a time, as I had a higher failure rate due to plastic shrinkage when printing many.
- Print with at least one shell, as the external and internal surfaces should be rigid, especially on the nut version ( to prevent the nut from slipping )
- print 2 of
mecanum_base_v3_flipped.STLand 2 of
mecanum_base_v3.STL, these will be our "hubs".
- more instructions soon!
