  3. 3. 一見なんの変哲もないミニ四駆
  4. 4. じつはBluetoothラジコン!
  5. 5. プロポ風のAndroidアプリ
  6. 6. GitHubにて公開中 https://github.com/lipoyang/BluePropo
  7. 7. システム構成 Android DC モータ 駆動輪 ステアリング DRV8830 Bluetooth モジュール RC サーボ GR-KURUMI Vbat 3.3V UART Bluetooth PWM I2C バッテリー 単3型×2セル バッテリー 二輪駆動なので 正確には ミニ四駆ではない
  8. 8. なんとか走ったけど… http://youtu.be/NkjMt1KF-MM ミニ四駆にしてはおそすぎる
  9. 9. 問題点 モータードライバの損失 →アルカリ乾電池2セル(3V) では電圧不足 →LiPo電池(3.7V)に変更
  10. 10. 改良版の実体配線図 BlueMaster GR-KURUMI DRV8830 DC Motor RC Servo LiPo Battery Switch Silicon Diode x 2 昇圧回路の入力を 3.3V以下に 落とすため
  11. 11. 改良後の車体
  12. 12. 使用コンポーネント一覧 ミニ四駆 レーシングミク 2012ver. アスチュート (スーパーIIシャーシ採用) マイコンボード GR-KURUMI (RL78/13Gマイコン) Bluetoothモジュール 浅草ギ研 BlueMaster DCモータードライバ DRV8830モジュール (ストロベリー・リナックス製) ラジコンサーボ 京商 KS-23 (3.9gサーボ) LiPoバッテリー LiPo電池 3.7V 1400mAh (OLIMEX製) ステアリング機構 アルミ材などで自作 その他 スイッチ、ダイオードなど汎用部品
