We present detailed optical photometry for 25 Type Ibc supernovae (SNe Ibc) within d~150Mpc obtained with the robotic Palomar 60 inch telescope in 2004-2007. This study represents the first uniform, systematic, and statistical sample of multi-band SNe Ibc light curves available to date. We correct the light curves for host galaxy extinction using a new technique based on the photometric color evolution, namely, we show that the (V-R) color of extinction-corrected SNe Ibc at {Delta}t~10days after V-band maximum is tightly distributed, <(V-R)_V10_>=0.26+/-0.06mag. Using this technique, we find that SNe Ibc typically suffer from significant host galaxy extinction, <E(B-V)>~0.4mag. A comparison of the extinction-corrected light curves for helium-rich (Type Ib) and helium-poor (Type Ic) SNe reveals that they are statistically indistinguishable, both in luminosity and decline rate. We report peak absolute magnitudes of <M_R_>=-17.9+/-0.9 mag and <M_R_>=-18.3+/-0.6mag for SNe Ib and Ic, respectively.
