This a single axle for our 13" tiller tires. The hub is welded to a steel 3/4" diameter shaft with a standard 3/16" keyway. It is intended to be chain driven. We use this shaft on our snow plow along with 3/4" pillow block bearings.
These wheels and shafts work great with our wheel chair motors. To calculate the speed of the robot just take the output RPM * wheel diameter (in inches) * 3.14 / 12 = feet per minute.
These shafts are made to order and may require a 2-4 business days before shipment.
Steel Machine Key 3/16" x 3/16", 3/4" long. These keys are economical with high strength and will fit 3/16" keyways.
This ATR robot uses custom length sides and 10 inch tires. We have included everything to make it ready to run including batteries, controllers, chargers, etc. It has been fitted with a custom top cover.
2WD self balancing robot! This kit is a perfect plataform for learning Arduino, PID control, serial communications(Serial, I2C, SPI), PWM signals, IMU filtering, etc.
