Also they are a bit weak for using in the first couple of joints.</div><div>I am now liking the idea of a water hydraulic cylinder on the first 2 joints & using</div><div>the blue robotics waterproof motor for the last joint, wrist & jaws.</div><div>Ian Juby who is new to Psubs is an expert in robotics. Listen to him if he chimes in.</div><div>Also the motors would need a motor controller that limited the amp draw or you </div><div>could burn them out if they stalled.</div><div>Alan</div><div><br></div><div><img src="cid:1F23E354-D16C-487A-B9D6-4BC0C4DB6715" alt="image1.JPG" id="1F23E354-D16C-487A-B9D6-4BC0C4DB6715"><br></div><div><br></div><div><br></div><div><br>On 25/05/2020, at 3:37 PM, Brian Cox via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br><br></div><blockquote type="cite"><div><div style="font-family:Arial, sans-serif; font-size:10pt;"><font size="2">Hi All,</font><div><font size="2"> Thinking about oil filling this gear motor for a arm I have in mind </font></div><div><font size="2"><br></font></div><div><font size="2"><a href="https://www.alibaba.com/product-detail/90mm-Waterproof-PMDC-12v24v-worm-gear_60771058320.html?spm=a2700.7724857.normalList.40.74ab140ekRVq5Q">https://www.alibaba.com/product-detail/90mm-Waterproof-PMDC-12v24v-worm-gear_60771058320.html?spm=a2700.7724857.normalList.40.74ab140ekRVq5Q</a><br></font></div><div><br></div><div><br></div><div>Brian</div><div><br></div><div><br></div></div>
