We present the results of our new CO survey of Very Low Luminosity Objects (VeLLOs). The observing targets for the VeLLOs were newly selected from the Herschel Science Archive catalog of the faint point-sources having an internal luminosity less than 0.2 L?. This resulted in the most complete catalog of 445 VeLLOs from nearby star- forming regions. We used a TRAO-14m telescope (angular resolution of ~47” at 115 GHz) to search for an outflow activity in the observable 158 targets in the northern sky in CO and 13CO J=1-0 lines in OTF mode. So far, we observed a total of 183 VeLLOs over ~5 x 5 arcmin^2 area for each source in a RMS of 0.3 K and a velocity resolution of 0.12 km/s. In this presentation, we will report the observing results of the outflow search in the VeLLOs and discuss implications regarding the mechanisms of low-mass or brown dwarf formation.
