The UBTECH Robotics Walker S2 robot battery swap demonstrates a robot that can operate indefinitely.
The robot has two battery packs, thus allowing one to be removed and placed in the charger before a fully charged pack is taken from the charge station and placed in the robot.
Uses: Factory floor automation, assembly line co-worker, logistics material transport, quality control inspection, battery swapping and maintenance tasks [2].
Battery pack specifications:
- Total energy = 2.3 kWh
- Nominal voltage = 48 V
- Power demand
- Average = 1.5 kW during operation [2]
- Peak = 2.2 kW under load [2]
- 2 hours active operation per battery charge [1]
- assuming this is a single pack => average power demand = 1.15 kW
- Charging
- 90 minutes for a full recharge
- 3 minutes for autonomous hot‑swap exchange
- Operating Temperature
- 0 °C to 45 °C optimal
- survival −10 °C to 60 °C
