Ardumower 1.0 Chassis specifications
- Dimension (L/B/H): 60x36x25cm
- Total weight: approx 9 kg (including all components - motors, battery, PCB etc.)
- Adjustable mower motor height
- Mowing motor: 24V DC, 3150 rpm, 140 mNm, 46W
- Mowing disc: 190mm diameter, 3 blades
- Wheels: 250mm diameter
- Free wheel: 125mm diameter
- Gear motors: 2 x DC 24V planetary drive, 31 rpm, 2.45 Nm, 8mm shaft, with integrated encoders
- A rotation speed up to 31 rpm allows to move the robot at sufficient speed (at up to meter/sec = 31rpm/60 * PI * 0.25m = 0.4m/sec using 250mm diameter wheels)
- A high torque (2.45Nm) guarantees that the robot can climb small hills as well (with 2 motors, 0.125 radius wheel, 31rpm = 0.4m/s, acceleration = 0.2 ( 1/2 of nominal speed) see calculator
- Integrated encoders, so it can measure the rotation speed and the distance
- Battery: Lithium-Ion 29.4V
- Max. incline: approx. 30%
- Material: PE-HD plates (8mm) and alumnium profiles
