Product Description

Robotic arm for Arduino IDE

The servo servo is mounted on the robot arm. The structure has a certain range of motion, which may be smaller or larger than the range of the servo servo. This kit does not include batteries, you need to bring your own

When debugging, be careful not to block the motor. Pay special attention to this when debugging the manipulator gripper.

Pay attention to the line sequence when connecting the servo motor to the controller. Do not insert the wrong positive and negative poles.

The servo servo control line: usually red is positive, black or brown is negative, yellow or white is the signal line.

Designed for beginners and professionals to learn arduino, robotics, programming and electronics.

Flexible arm claw

This robot kit provides 4 Gear Servos of 180 Degree which can easily control the robot arm claw and make the robotic arm move flexibly that can grab objects in any direction. You can program the servo to adjust its angle.

Joystick Control

The 2 Joystick modules allow you to control the robot arm in different actions.

Be careful when connect the module to the servo Shield. Follow the assembly guide and project 5 instructions.

Bluetooth APP control

KEYESTUDIO robot arm are able to use either Android or iOS system APP to control the robot arm via connecting BT-24 module.

Very happy with this little bot
I’ll start with the wiki. The arm comes with a parts list in the form of a pamphlet within the box. There is a QR code on this that will take you to the Keyestudio wiki and on this page you will find a search bar. I believe I searched something like “4DOF Arm Kit” and some suggestions came up (make sure you select the V2 instructions).Very cool little robot arm, the provided code works great and if everything is plugged in correct; runs flawlessly. The “arm” unit comes preassembled so you’re basically just going to be attaching that to a base you put together and coding it to work.Biggest problems are the weird 18650 batteries you’ll need to get to use the provided battery pack.This is one of those devices that will do WEIRD things when undersupplied (like whip or spin around all crazy) These batteries are 4.8V-5V rechargeable batteries (so a 9v battery won’t do if you want to drive all 4 motors simultaneously) I also ran into trouble with the servos; after 3-5 minutes of use (only occasionally being driven) they started seizing up and about 2 days later I have only 1/4 servos still working. (the others spin freely in the casing and get very hot but do not actuate the gears inside anymore.) Hard to say if this is standard quality control or if this was the weird 18650 batteries frying my servos *shrug* either way; learned a lot and have a lot of questions I’d like to go find the answers to.Final thoughts: if you were going to order this, consider picking up some extra metal geared servos and 18650 batteries or a suitable replacement battery pack.**UPDATE**Replaced the 3 broken servos with new motors. Works great now. My base servo has a little “Jig” to it (visible in the video, this is the only keyestudio servo still on the bot so these servos must not have great QC). Link to replacements I used included below. They all work and fit the build. The final tip I can give you is to make sure to test all your servos actuation between 0-180 before running this thing. Specifically the forward and back and up and down servos are placed in such a way that they are sometimes in competition if not installed correctly which will break them. All in all: 4/10 on difficulty for most people, 3/10 on quality of included parts, and 5 stars because this was all very fun.(https://www.amazon.com/MG90S-Servo-Motor-Helicopter-Arduino/dp/B01JY3H4MA/ref=mp_s_a_1_2_sspa?keywords=9+gram+metal+gear+servo&qid=1659280156&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFLOFMxQjZJRjEzVUcmZW5jcnlwdGVkSWQ9QTAxNTQ4ODhJNE5WUElWRkdKSVYmZW5jcnlwdGVkQWRJZD1BMDU5NTkxNDJLNVVLN1I3MzJYUlgmd2lkZ2V0TmFtZT1zcF9waG9uZV9zZWFyY2hfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==)

Reviewed in Japan on September 19, 2020
まずパッケージが綺麗でしたので、写真付で。
この手のキットはパーツリストすら提供されていない物が見受けられるのですが、これはパーツリスト添付。しっかりチェック出来ました。
組立の説明書はオンライン供給ですが、添付されていた書類記載のQRで飛んでも目的のページには行けませんでした。検索方法が書かれているので、その手順に従って探す必要有りです。説明書の記述はとてもわかり易いものでした。
組立時には、サーボの角度調整等を行なうのでarduinoへのプログラム書込みが伴います。要PC(windows機)ですね。これは販売ページに書いておくべきだと思いますが。
arduino統合環境を使った事が無い人には若干敷居が高いかも知れませんが、ググれば初心者向けの解説は沢山有るので、心配無いでしょう。
…さて、組み立ててみるか。

ヤスリが必要有りでした。サーボ取付ブラケットの取付穴が若干狭く、削ってやらないと取り付けられませんでした。
長手方向の縁をごく僅か(0.1mm程度かな)削ってやる必要がありました。
また、付属のドライバーは先が小さいので、M3ネジを締めるのは厳しいですね。#2ドライバーを用意しておくと吉でしょう。
最大の問題は電源かな。USB給電ではarduino へのプログラム書き込みしか出来ません。キットは18650バッテリーを2本使用する事を前提にしているのですが、保護回路も無しでリチウム電池を使うのはちょっと怖い。充分な容量を持った7~9VのACアダプターを接続するのが良いかと思います。
まとめておきます。
別途必要な物:
・電源(7~9V)←2A以上は欲しいかな…(追記:5Vで行けました)
・ヤスリ
・#2プラスドライバー
追記:
あまりにも基本的な事で忘れていましたが、ラジオペンチが有った方が組み立ては楽です。結構大量にロックナットが使われていて、付属のスパナはサイズ違いのために使用不可でしたので。
また、インターフェース基板の仕様が不明でしたので、サポートに問い合わせしてみたのですが、とんちんかんな回答が返って来ました。(笑)
アテにはならなさそうですが、レスポンスは速かったので、くじけずに何度か連絡すれば求める答が得られるかも知れない…と言った感じで行くと良さそうです。
9/29追記:
3回質問して、拡張ボードの回路図を送って貰えました。回路図を信頼するなら、ボードに供給する電源は12v程度まで大丈夫ですね。ただし、使用されているコンデンサの値が回路図記載の容量より小さい(多分、コストカットのために他の物と同じ容量にしたんでしょう)など、信頼しきれない部分は有りますが。まぁ、配線パターンは変更していないだろうから、多分大丈夫かと。
