Battery apparatus for a robot, methods, and applications
A robotic vacuum cleaner equipped with a holonomic drive that can drive in a given direction, e.g., north (assigned orientation), and move in a different direction, while maintaining its assigned orientation or that of any desired portion of the robot, such as an intake, or any other portion of the robot that is needed for a particular maneuver. The robotic vacuum cleaner includes a removable, chargeable battery system including a battery pack having batteries and a battery management system extending across all the batteries of the battery pack. A housing, including a top cover, surrounds the battery pack and the battery management system (BMS). The top cover extends over the BMS and includes a circuit board therein. A connector is at least partially connected to the BMS and extends through the housing. The connector is configured to transmit signals between the battery management system and the robotic vacuum cleaner.
1. A robotic vacuum cleaner, comprising:
a main body having a front, top and bottom;
a vacuum source positioned at the front of the main body;
a plurality of sensor elements mounted to the main body;
a plurality of wheel assemblies that collectively form a holonomic drive, each wheel assembly comprising:
a motor;
a drive wheel connected to the motor;
an encoder;
and a motor controller;
a main controller that receives odometry data from each motor controller in regard to the movement of each respective wheel, and data from the plurality of sensor elements, and provides electronic navigation control to the plurality of wheel assemblies;
a socket including a connector;
a removable, chargeable battery system within the socket on the main body, comprising:
a battery pack with one or more batteries;
a battery management system extending across all of the one or more batteries of the battery pack;
a housing configured to store the battery pack and the battery management system therein, the housing also having a translucent top cover, which extends over the battery management system and which forms a top surface of the main body of the robotic vacuum cleaner when the removable, chargeable battery system is within the socket;
a circuit board within the top cover of the housing, the circuit board including a light source to illuminate through the translucent top cover of the housing, and the circuit board including a touch sensor to control the light source to indicate a charge status of the battery pack when a touch is sensed;
a connector of the removable, chargeable battery system at least partially connected to the battery management system and extending through the housing; and
wherein the connector of the removable, chargeable battery system is configured to transmit signals between the battery management system and the main controller via the connector of the socket.
2. The robotic vacuum cleaner of claim 1 , wherein the touch sensor comprises a capacitive touch sensor.
3. The robotic vacuum cleaner of claim 1 , wherein the-light source comprises LED lights.
4. The robotic vacuum cleaner of claim 1 , wherein the connector is configured to mate with a connector of a charging station.
5. The robot vacuum cleaner of claim 4 , wherein the housing is configured to fit within a slot on the charging station.
6. The robot vacuum cleaner of claim 1 , wherein the housing further forms a back surface of the main body opposite the vacuum source of the robotic vacuum cleaner when the removeable, chargeable battery system is within the socket.
7. The robot vacuum cleaner of claim 1 , further comprising:
a reserve power supply charged by the removeable, chargeable batter system when the removeable, chargeable battery system is within the socket, the reserve power supply to supply power to the robot vacuum cleaner when the removeable, chargeable battery system is removed.
