SZDoit Professional Metal Tracked Robot Tank Chassis for Arduino/Raspberry pi Project, Track Smart Car, Robotic Frame for Robot Project Graduation Design YP100

Directions were not the best as others have mentioned. I like that it is all metal except for the idler wheels which I think are ABS and the tracks. Yes the tracks are too long but you can easily remove the pin and make them fit snug. I just ordered the ts100 with shocks. Looking forward to building that one. I would buy another and I may for a halloween project.

Nice kit, but instructions lacking. No locking nuts, washers or thread lock. No info on the motors or in the kit. Some of the screws were substituted. Extra screws provided. Does not look like the motors can be removed without partial disassembly. If it was a bit wider that would not be a problem. I chose this model because it does NOT have a suspension and needed more stability. I very much like that parts are available. The tracks are plastic, but it looks like metal is available. Overall, a good deal.

Looks like a very cool thing. Can’t wait to assemble it. But WHERE IS A DETAILED INSTRUCTION/ASSEMBLY MANUAL?EDITED/CHANGED TO INE STAR. ASSEMBLED BUT..: THE TRACKS ARE WAY TOO LONG. HELP!!! THIS THING IS USELESS TO ME!

Terrible instructions...don't put the wheels on first as suggested, as you'll just have to pull them off again to access the screw holes for body assembly.Terrible selection of screws/nuts (should've been nylock nuts, and countersink screws require countersunk holes).Too cheap to provide extra screws, and inevitably there's at least one with bad threading.Some genius thought it was a good idea to remove the stickers from the motors (adhesive residue still present), because it's not as if the motors' electrical specs might be useful to anyone building a robot.One bad bearing, so of course now there's a wheel which doesn't roll smoothly.Body panels are okay, but chipped paint due to being bagged together.This kit should be priced closer to $20, maybe.

used as base on a robotic project, works well, tracks are plastic and dc motors produce allot of emf noise, ended up isolating them and the motor driver with opticouplers to stop it resetting my i2c devices other wise love it

The plastic tracks aren't great but other than that you get exactly what you order. I do need to contact support though, because unless there is something I'm missing the tracks are about 2 inches to big and just hang too loosely over the support rollers.

can not the battery box it come with can not find this type of batteries in use they use 3.7 volt not 1.5 or 9 volt
