Robot Battery

[Azalee Freas]

Itshould have at least the most basic li-ion charging circuit, that includes overcharge protection. If mine starts acting up I plan to install in-line volt/current monitoring to see what it actually does.

A quick search for INR18650 MH1-4S1P-SC shows AliExpress has a replacement battery. It fits the Xiaomi vac which is the company that makes the Wyze robot vac.

Unfortunately they seem to be the only place to buy one.

Replacing the battery is easy. Remove the roller brush cover and you will see 4 small Philips head screws holding a cover down. Remove these screws, lift the cover off, pull the battery out, and disconnect the plug from the vacuum. Installation is the reverse of removal.

Andrew made this battery powered robot to demonstrate motion made from household supplies for the Boy Scout Engineering Merit Badge. I love scouting! Merit badges are like mini high school courses with a seasonal reward ceremony. Here is his $1.00 robot he made with the motor from a battery operated toothbrush from the Dollar Store. The rest of this post is Andrew written. Here is how to make a robot!

Note from Mom** An adult should always help with a hot glue gun. I keep a cold glass of water near by. If hot glue gets on fingers or if you accidently touch the tip of the glue gun, you can immediately immerse the area into cold water. It will harden the glue so that it can be removed with minimal abrasion. The initial reaction is to take a swipe at hot glue as soon as it touches skin- this smears the area and makes the burn larger. I repeat this safety lesson each time the hot glue gun gets plugged into the wall!

Buy a battery operated toothbrush at the Dollar Store. You might as well buy more than one because you can make all kinds of robots with them. My Crayola Scribble bot is only one type. You can make robots from many type of materials, however in this case, you will need a 3 inch pool noodle. You can also purchase pool noodles at the Dollar Store during spring and summer.

Robots with silly faces or dressed up are crazy. Find odds and ends of decorations to use for your robot around the house. You will need to use a hot glue gun to hold the decorations to the pool noodle. School glue and a cool glue gun did not work for us. When you have all this assembled, create a personality for your robot!

Pull off the bottom of the toothbrush. This is the area where you will either find a battery or you will insert a AA battery. Look up inside the toothbrush and you will see a spring. Behind the spring is a motor. Tap the toothbrush end on a hard surface until the battery unit and motor falls out.

Insert the taped motor into the hole in the center of the pool noodle. If if is too tight, use a knife to shave the hole bigger. You should probably make sure you have an adult with you. Push it down inside so that only the end of the on/off compartment shows.

The oscillator spins so quickly that it transfers energy to whatever it touches. You can feel the energy, either in your hand or teeth, and it is the same energy that oscillates the robot in a circle.

I would like to let everyone know the AliExpress part number circulated above worked for me and arrived the fastest. I ordered it on Feb 20, it arrived on March 3. (11 days) to transit from China to Syracuse, NY with the standard shipping offer. Quite impressive. I placed a duplicate order in parallel from another seller on e-Bay for the same part, also shipping from China and it was a few dollars more, but it has not arrived yet. (22 days and counting). The promised delivery dates for both were mid-March to the end of April. But AliExpress seems to have their shipping process down and appears to be delivering product much quicker than promised.

Thank you whizzysyr. I ordered my battery from AliExpress on March 3rd. The delivery ETA is early May. Hopefully it will arrive sooner. Good to hear the replacement worked well. Thx for the heads-up on the possible battery charging issue on first use. Agree about Wyze not providing this easy direct battery swap as an option, It sounds lke a no brainer.

A cordless vacuum I have, on first use they wanted you to use it until depleted (turns off on its own), then charge to full in order to calibrate the charge percentage. It has a removable battery pack, so maybe the battery has a fuel gauge type chip that keeps track.

Appreciate the immense details in the thread above and am leaning towards getting a new battery but was curious what any of you are experiencing following battery replacement regarding life of charge during a task.

Thank you

Agreed - curious that this new battery supposedly uses the 18650 cell size and is a perfect size and fit for the original 3000mAh battery. Not sure I understand how this new battery can then be rated for 6000 mAh

I'm just starting my adventure with robot programming as a junior engineer. In the past I used to be in contact with ABB and OTC robots, and now my job is to program the Kawasaki FS20N polishing process for the new company. I have two problems and I kindly ask for help.

One of the employees accidentally just typed in the "exe" command (without program name after "exe") and approved it. The robot moved forward and the J5 axis bent and damaged the pneumatic spigot. We quickly stopped the robot in an emergency and replaced the spigot with a new one. After restarting the robot, a "W1013 encoder battery low voltage [Servo(0)]" error appears on the computer screen and a red error light on the control cabinet keeps lighting up. After deletion it, I tried to put the robot in the starting position manually, but the robot is behaving strangely. In a kind of "base point" control the axes do not work properly. The robot moves in different axes and directions than I control. What battery should I buy and where is it located to replace it? Is it enough to change the battery and it should be working again?

I wrote the program about a month ago and it worked without problems. The boss asked me to back up the program for fear of losing data. So I downloaded the programs from the robot's memory to a CF card (the first time I had one in my hands ) and took it out. Out of curiosity I turned on the program without the card and it turned out that it worked, so I left it like this, without the card inside. It turned out that after one of the sub-programmes was done, the polishing discs stop working, even though the robot is still making the right moves. What should I do? Is it enough to upload the programs back into the robot's memory? I can insert a screenshot of the program here.

If the collision applied enough force to the wrist assembly (dependent of variation of model), sometimes the gear pulley attached to the motor shaft rotates (tapered fitting) is also forced around - this causes the physical wrist to mechanical spin - resulting in JT5 being out of mechanical zero.

Therefore, JT5 should be inspected by removing the side cover for any further damage (take care in there, belts are located for JT5 and JT6 and are not finger friendly.....so no touchy touchy until you have isolated the power during inspection).

Oh my mistake, I'm still learning all the different models. I don't want to high jack this post and can contact my distributer. Id be looking for a Zx series, RD series, and a RS series Zeroing and motors instruction manuals

Today I got the betteries and I wanted to replace them. I tried to set up the robot so that each axis was in the 0,000 position and and noticed, that axis 3 and 6 don't move in "plus" direction. I am 99% sure that gears are not broken. My hit was really light. Do you think the reason is low encoder battery or it may be more serous problem? Should we call the service guys?

If there is any zeroing data loss, it is probable that the encoder values will be different than to what it was calibrated before, therefore these 'new' values will be used to calculate joint angles and probably exceed either the minimum or maximum software limits.

Check out this guy. He replaced his original battery pack with better batteries for his Gibson Robot. The originals have a terrible shelf life and loose power quicker than the metal based batteries mentioned in this article. They also cost around $60 bucks. He describes how he replaced the originals with batts. off the shelf for a better experience. Let me know if anyone else has had a similar experience: =1130. I'm thinking about going this route with my Ebony, 2009 Les Paul ROBOT.

I know this is an old thread but, I did the same thing and it works great! $5 pair of NiMH AA batteries on Amazon, some hot glue, solder and electrical tape. My 2008 Wine Red LP Robot Studio works like new again. Took about 15 min at a leisurely pace. I'd considered the "un-robot" procedure but given that there a no issues anymore, I might just leave it be until a tuner or something else fails.
