RoboPad

The RoboPad charging contact system offers a precision,

high current charging solution for mobile robots and

Automated Guided Vehicles (AGV).It is composed of

a charge contacts base that is typically afﬁxed on the

ﬂoor, and a collector unit with extendable contacts,

mounted on the robot. Unlike conventional spring-loaded

contact products commercially available, RoboPad

utilizes high energy magnets to control the connection

and disconnection action automatically, while using no

additional power from the mobile systems batteries. The

magnet’s strong attractive action result in a high pressure,

high quality electrical contact. The magnet’s repelling

function actively forces the pads retractions as the robot

moves away. The base’s ultra-low proﬁle, and the collector’s

extension range, allows for far more compact charging

conﬁgurations over any other charge system, in permanent

factory and business environments.

Description Description There are few commercially available options available today for performing the charging function of a mobile robot or AGV. The majority of them use weak spring loaded copper or brass contacts which use the shape of the contact to ride over the charging pad, creating considerable wear and tear on the system. What is needed is a rapidly connecting, low wear contactor that can supply high current for extended periods and disconnect without creating damaging electrical arcs.

Figure 4. Charge pads located at charge parking To charge, the robot or AGV simply drives over the charging pads on the floor. When the robot’s collector pads are aligned with the base, they instantly extend. By detecting the charge voltage directly, or monitoring the built-in sensor in the charging contacts, the robot can determine when to stop. Current can then flow to the battery to charge it.

Benefits over brush/springs Benefits over brush/springs Conventional charging contacts use spring loaded collector contacts which drag or hang underneath the mobile robot in use. These units have a low floor clearance and tight height tolerance as they must physically slide up a ramp on the base: if they are mounted too low, they will touch the floor or hit the side of the base. If they are mounted too high, the will have weak spring pressure or not make contact at all.
PAGE 6
Hall switch Located on the side of the charging contact housing is a Hall Magnetic Sensor. This solid-state device is located near one of the retractable collector magnets and changes state when the pads extend or retract, providing the robot’s Battery Management System and/or supervisory computer with this important information. Mounting and Wiring Mounting the charging system underneath the AGV/Mobile Robot is the most commonly used option.

Connecting to the hall sensor. On the robot side, the collector contacts unit attaches to the AGV or Mobile Robot with four 4mm screws. Connection to the collector contacts is made with ring lugs and 8-10 AWG wires to the robot’s battery system. For best results, the user’s ring lug must be placed directly over the ring lug that connect to the copper braid on the charging contacts. OK Figure 10.
