PAV(空飛ぶ車)を作りたい
世の中にはPAV(Personal Air Vehicle)
というジャンルがあるらしい。
自動運転とドローンの技術を併せれば
実現可能ではないか。
出遅れないよう流行りに乗っかって「人
工知能」、「ドローン」、「 3Dプリン
ター」、「IoT」、、、やらを何となくかじっ
てみる。
何すればいいんだろう?
自分で描いてみるものの、あまりにダサい。。。
たまらずFusion360が得意な友人にHelp!
プロペラ&タイヤを付けてみる
とりあえずデザイン
とりあえずドローン購入
近年、流行っているドローンレース用の FPV。
こいつにタイヤつければいけるのでは。。。 こんな感じ?
FPVを組み立てて、まずはその仕組みを理解する。 ebay(米国オークションサイト )でパッケージ化され
たFPVを購入。
とりあえずドローン組立①
組み立ての説明書は一切ナシ!
教科書はYouTube!
ラジコンをやっている人からすると割と
シンプルで簡単みたいだが、自分には
かなりハードルが高い。。。
dji等の市販品のドローンばかりで、
DIY用のドローン情報は意外と少な
い。
とりあえずドローン組立②
構成のメインは以下3つ。
①ESC:モーター電圧を変えて回転スピードをコントロール。
②PDB:配電盤。バッテリー電源を各パーツへ供給する。
③FC:フライトコントローラ。FPVの頭脳。
FC(フライトコントローラ)1つとっても様々な種類がある。
中でも一番情報が多く落ちている「Naze32」を使用。
とりあえずタイヤをつける
ドローンのフレームにタイヤをつけて陸走できるよう
にしたい・・・
以下、2択で②を選択した。
①ミニ四駆orラジコンをドローンのフレームに
 そのまま結合する。
②3Dプリンターで専用フレームを自作して
 そこにタイヤを装着。
とりあえずフレームを作る
中古で3Dプリンターを購入(¥15,000) 自作フレーム初号機は、強度がかなり
弱く敢えなく撃沈。。。 (試作継続中)
とりあえずマイコンを試す
最終的に自律飛行するためにまずは、
3軸加速度センサーのデータを取得。
リアルタイムモニタリングを試みる。
リアルタイムは難しかったので、
蓄積したセンサーデータを BIツールを使っ
て分析。機械学習用のネタ探し。
とりあえずDeep Learningを試す
いきなりTensorFlow!とは行けず、まずは、、
Pythonを使ってJupyter Notebookでデータの読み込み。
慣れてみる。。。慣れない。。。
Deep Learningもその仕組みから理解する
ために勉強会に参加しながら精進中。
