Abstract
This page describes (as a 'hack') how to modify the Ardumower Chassis to run up higher slopes with it (tested up to 30 percent). This works by
- turning the front drive into a rear drive and so requires to reverse the drive direction (so front is back and back is front)
- optional: modifying the tire profile (give it more grip)
- Modify tire profile OR
- Off-road version (sand etc.): A bicycle tube or U-form rubber is added around the tire
Needed parts
- cup
- acrylic glas sheet (1mm)
- rubber band (U-form)
Turning front drive into rear drive
- on Ardumower PCB, swap right motor cables with left motor cables (so left motor is right motor and vice versa)
- on Ardumower PCB, swap polarity of each motor by swapping motor (+/-) pins (so turning forward is turning backward) NOTE: for brushless motors, swap two arbitrary phases (U,V,W) to swap motor polarity
- on Ardumower PCB, swap odometry cables (so left odometry is right odometry and vice versa)
- mount battery charging pin at chassis handle side
- disable ultrasonic sensor
- move perimeter coil from old front to old back side (if using perimeter sensor)
- use BumperDuino as bumper sensor
New rubber tires (optional)
For even higher traction, one can use pushcart tires from the shop. Using a 3d printed adapter one can mount them onto the Ardumower clamping element. NOTE: The trick here is to first insert the long screws into both printed adapters, and then rotate the adapters until they fit onto the tires.
