Embodiment Construction

[0021] figure 1 A remote-controlled demolition robot 10 is shown, hereinafter referred to simply as robot 10 . The robot 10 comprises one or more robot parts, such as an arm 11, which can constitute one (or more) robot arm parts. A component can be used to hold the accessory 11b ( figure 1 not shown, see image 3 ) accessory tool holder 11a. The attachment 11b may be a tool such as a hydraulic breaker (or hammer), cutter, saw or digging bucket to name a few. An accessory may also be a load carried by the robot 10 . The arms 11 are movably operable by at least one cylinder 12 for each arm 11 . The cylinders are preferably hydraulic and are controlled by a hydraulic valve block 13 housed in the robot 10 .

[0022] The hydraulic valve group 13 includes one or more valves 13 a for controlling the flow of hydraulic fluid (oil) supplied to, for example, the corresponding cylinder 12 . Valve 13a is a proportional hydraulic valve.

[0023] The valve block 13 also includes (pos...

Abstract

A remote controlled demolition robot (10) comprising a controller (17) and at least one actuator (12) controlled through a hydraulic system (400) comprising at least one valve (13a) and a hydraulic gas accumulator (440), wherein the controller (17) is configured to determine a fluid flow in the hydraulic system (400), determine if the determined fluid flow in the hydraulic system is above a firstthreshold, and if so discharge the accumulator (440) to provide power to the actuator (12); and determine if the determined fluid flow in the hydraulic system is below a second threshold, and if so charge the accumulator (440) for buffering power in the hydraulic system (400).

Description

technical field [0001] This application relates to powering remote controlled demolition robots and in particular to improved buffering in hydraulic demolition robots. Background technique [0002] Modern remote controlled demolition robots have the problem that they sometimes work in remote areas where they can only be operated on battery power. Or in environments without high power outlets. For example, only 16 amp electrical outlets will work. Because demolition robots sometimes require higher currents to operate, such as during the use of tools, demolition robots will not be effective in such environments. [0003] To overcome this problem, state-of-the-art demolition robots carry batteries to boost power when needed. However, batteries discharge and charge much slower than they discharge. Therefore, the use of batteries limits the operating time of the demolition robot. [0004] There is therefore a need for a remote controlled demolition robot that can operate ade...
