SLAM?
 Estimasi Lokasi & Pemetaan secara Simultan
• Explorasi area
• Deteksi & identifikasi obyek
• Obyek lama :
• Estimasi lokasi robot
• Kalibrasi peta
• Obyek baru :
• Pengkinian peta
Riset Sebelumnya
 Estimasi lokasi (Durrant-Whyte & Bailey, 2006)
 Representasi data robotik dalam vektor (Pradhana, 2013)
 Partisi peta SLAM kedalam peta lokal (Chong & Kleeman, 1999)
 Pengolahan data SLAM (Pratama, 2013)
 Pengolahan dengan DW disajikan dalam OLAP (Hammergren &
Simon, 2009)
 Sensor Robotik (Ruckert, 2009)
 Karakteristik sonar (Saleem, 2013)
 Motor Robotik (Pal & Tripathy, 2011)
 Motor Stepper (Singh dkk, 2010)
 Sistem koordinat (Strang, 1991)
 Operasi vektor (Peacock, 2009)
Tujuan & Manfaat
 Tujuan : Menerapkan sistem OLAP untuk mengolah data
SLAM yang mampu :
 Menampilkan peta
 Mengetahui posisi terkini agen relatif terhadap peta
 Menginformasikan area-area potensial yang belum
dipetakan
 Manfaat :
 Menunjang sistem kerja elektromekanik
 Observasi non destruktif
 Interpretasi visi robotik
 Visualisasi kondisi & posisi robotik
Analogi Peta Pegas (Durrant-Whyte,
2006)
Menggambark
an beberapa
korelasi antara
robot dengan
obyek-obyek
di sekitarnya.
Mengestimasi
korelasi antar
obyek yang
satu dengan
yang lain.
Mengestimasi
posisi robot
dan obyek
pada peta.
Metode SubMap (Chong & Kleeman,
1999)
Peta Global,
obyek-obyek
hasil deteksi
sebelumnya
Peta Lokal, obyek-
obyek hasil
deteksi baru
Konsolidasi
informasi,
pengkinian
peta global
dengan
informasi-
informasi dari
peta lokal.
Asumsi
 Posisi dan jarak antar obyek random (tidak teratur)
 Bentuk dan ukuran obyek sama (silinder)
 Robot tidak memiliki sistem navigasi
 Tanpa kompas, tidak tahu menghadap ke arah mana
 GPS, tidak tahu sedang di koordinat berapa
 Drop point robot random
 Sensor & Aktuator robot ideal
Tantangan
 Estimasi lokasi robot
terhadap peta
 Konsolidasi peta lokal
pada robot terhadap
peta global
 Kolom, Baris  Peta
 Data Numerik  Data
Geografis
 Mempertahankan
informasi
