Embodiment Construction

[0058] This chapter describes the creative design of bogie arm 4 and traction counterweight 9（ Figure 1A B), by attaching one or more counterweight modules 13 to the bogie arm extension 12, the gravity acting on the driving wheel 6 and the generated friction can be increased, and the generated gravity acting on the (front) caster 7 can be reduced due to the cantilever effect. Therefore, it is relatively easy to achieve sufficient traction for the intended application on the driving wheel 6 without affecting the safety, and the impact on the overall energy efficiency of the mobile robot 1 is minimal.

[0059] The available traction force of the driving wheel 6 of the mobile robot is directly proportional to the normal force generated by the gravity of the robot on the ground and depends on the friction coefficient between the ground and the wheel thread（ Figure 2A )：

[0060] F T ＝F N * μ

[0061] among μ Is the coefficient of friction; F N Is the normal force.

[0062] The robot d...

Abstract

The invention relates to a basic mobile robot (1) in which the weight on the drive wheels (6) can be adjusted in order to achieve optimal traction and braking performance of the mobile robot (1) for related applications. With the inventive design of the bogie arm (4) and the modular traction weight (9), the gravity acting on the drive wheels (6) and the generated friction force can be increased by attaching one or more traction weight modules (13) to the bogie arm extension (12), while the generated gravity acting on the (front) caster (7) is reduced due to the cantilevered effect. Thus, it is made relatively easy to obtain sufficient traction on the drive wheels (6) for intended application without affecting safety and with minimal impact on the overall energy efficiency of the mobile robot (1). The mobile robot (1) may be configured for various applications, including transporting goods loaded on top of the mobile robot (1), cart pulling or automatic dragging of material within a room.

Description

technical field [0001] The invention relates to a basic mobile robot, which can be configured for different applications, including the transportation of goods loaded on the top of the mobile robot, cart traction or automatic dragging of materials indoors. More specifically, the invention relates to a mobile robot in which the weight on the driving wheel can be adjusted to achieve the best traction and braking performance of the mobile robot for related applications. Background technology [0002] The transportation of goods within a structure or between multiple structures has caused problems to some extent. Today, many transportation options exist as commercial products, such as conveyor belts, pneumatic tubes, universal carts and mobile robots. Mobile robot or automatic guided vehicle (AGV) is a vehicle equipped with a computer-controlled drive system, which allows autonomous guidance between two positions. [0003] A towing Trailer with a towing device mounted on an AGV is we...
