DS 4WD Robot Chassis

I mean, it's 20 bucks so you can't expect too much, but what you get is a really impressive platform for playing around with robotic possibilities using your Ardiuno or Raspberry. The kit is light on instructions so you'll spend a little time figuring it out and getting it right but I got it done in a couple of hours, including wiring. The wire they send for the motors is thin and stranded, and would have been hard to attach to the terminators at both ends, so I used solid core instead. I used some of the bag of extra nuts and bolts they included to attach my Pi. Nice touch.

I have mixed feelings about this chassis. On one hand, it's made from thin and strong fiberglass circuit board material, and it's got a lot of pre-drilled slots and holes for mounting controllers and sensors to it. You CAN fit both an Arduino and a full sized Raspberry Pi computer. There are all sorts of screw holes and slots to mount other devices and sensors, but aside from a set of holes for a pan/tilt assembly, and a couple holes for some IR sensors, I can't think of anything else that matches. Except that it has the crossed slots for a photo interrupter module for a slotted wheel tachometer--But no mounting hole(s) drilled for it. Also the crossed slots are completely blocked if you install an Arduino in its position, and crowd the Raspberry Pi mounting area. Again, if you do mount both an Arduino and a Raspberry Pi, you'll have trouble finding a spot for batteries and a motor controller. This board would be better served as part of a kit including a matched deck the bottom deck could have holes for AA, and 18560 battery holders, some of the popular motor drivers, and the motors. The upper deck could be layed out for an Arduino/RasPi, and a few sensors. All of that being said, it's strong and should be easy enough to drill through so I'll be using it in my next project.

There are 1 well designed PCB chassis, 4 yellow motors and 4 wheels, plus a bunch of screws and nuts. The assembly and wiring of motors are straightforward if you follow the instruction guide. The board is clean and firm to hold Arduino/Raspberry Pi module securely. The only issue is the rubber around the wheel is too soft. It is only a starter kit. You have to purchase add-on parts more if you want to create more. You need a motor driver and your own modules(Arduino/Raspberry Pi) before purchase it. Anyway, it is a very good gift for children interested in mechatronics stuff.

Did not include chassis...just (the) motors and wheels I bought two and both came the same way...waiting on a replacement but definitely sending at least one back.

A good kit to start out with. We bought this as a starter project car for my kids and I, so we could learn more about Arduino. It comes with a chassis, that can have an Arduino or RPi attached to it, motors and wheels. Also comes with a ton of various hardware for any add-ons you may put on it. You do have to supply your own motor driver and Arduino/RPi. But for the price it's a good starter kit for anyone that already has an Arduino on hand and you can easily get motor drivers from a ton of retailers online.

What you see is what you get, the PCB is sturdy enough to mount your Ardiuno or Raspberry on to build your own robot. It's a easy to assemble and a good starter kit.

I’m missing the wires for the motors, nuts and bolts, and screwdriver... the kit is good, I just can’t get started on it because I don’t have the wires..

Lightweight chassis. Wheels come off and the motors are held on by tabs instead of screwed directly to the board. One motor was broken on receipt and they shipped a new one, no hassle.

Ich habe mir das Chassis für den Bau eines Robot-Cars gekauft und wollte ein stabiles Chassis einsetzen. Positiv: Das Chassis wurde schnell geliefert und ist aus stabilen, beschichteten Aluminium, wie ich es erwartet habe. Es gibt viele Befestigungs- bzw. Installationsmöglichkeiten von Arduino und Raspberry Pi sowie Sensoren (Bohrungen, Aussparungen sind dafür vorhanden). Die Motoren funktionieren einwandfrei. Anlieferung im Pappkarton, zwar ohne Einzelverpackung, aber mit Kunststoffpolster ausgekleidet. Negativ: Der Zusammenbau gestaltet sich etwas schwierig. Die Motorhalterungen sind bei Auslieferung noch am Chassis und müssen mit einer Säge vom Chassis abgetrennt werden. Des Weiteren sind die Motorhalterungen mangelhaft, da die Motoren nicht fest am Chassis angebracht werden können. Das weitere Anziehen der Muttern würde vermutlich das Gehäuse der Motoren beschädigen/zerstören. Das ist ein konstruktiver Mangel und dafür gibt es einen Punkt Abzug. Letztendlich habe ich die Motoren mit Heißkleber fixiert, was aber nicht im Sinne des Erfinders ist. Ein Rad pendelt und läuft nicht rund, so dass eine gerade Fahrt nicht ohne weiteres möglich ist. Grund dafür ist zum einem die etwas schiefe Nut der Nabe und zum anderen ein etwas verzogener Reifen. Ich musste ein Rad nachkaufen. Dafür nochmal ein Punkt Abzug.

Jetson Nanoを搭載したAIカーを安くす作るために購入。ボードも適当にマウントでき走らせることができました。ただモーター4個の個体差と遅さなどで満足までには至らず。安く勉強するにはよい機材になると思います。 ＜追記＞ 購入してから半年が立ち数倍の価格変動に驚いています。今だったら買えないかな。
