Ascension – Wall Climbing Car

Tyler Madden, EEMarc Mitchell, Project Advisor

Abstract

Ascension is a remote controlled car that can climb any wall and theoretically even drive on the ceiling. Inspired by Disney’s VertiGo , Ascension doesn’t use vacuums to hold itself up, rather it uses controllable thrust vectors as its entire source of movement, has custom suspension and wheels, and is remote controllable for distances of nearly a mile.

Design

Results• Proof on concept - autonomously adjusts to counter gravity

in any given orientation

• Reads in commands from the user

• Motors properly adjust based on user commands

• Counters gravity if no user commands

• Suspension properly adjusts

• 3D printed mounts, wheel,

shocks, and frame

• Shocks allow for a smooth

ride and keeps bounce

through the system low

• Pro Trinket 5V reading the

long range receiver for user

commands

• Pro Trinket 5V reading 9-

axis-inertial measurement

unit to determine orientation

in space

• Motor speed controlled

directly with flight receiver

given user commands

• Motors mounted with servos

that rotate on two separate

planes to allow 2 degrees of

freedom

• Servo mounted beside the

motor allows rotation about

the roll axis

• Servo mounted on the

support allows rotation

about the pitch axis

• Together with the 2D

readings from the IMU, a 3D

thrust vector is created to

propel Ascension

• Two electronic speed

controllers, ESCs

• Converts the dc source from

the battery into a 3 phase ac

source to power the

brushless motors

• Speed of the motors will

vary based on the applied

voltage, 0 – 11.1V, user

controlled with the

transmitter

• 12V power supply from

ESCs to buck converter to

power all communications

with 5V and 2.5A

Ascension incorporates a Pro Trinket 5V processor as the master device and reads from a flight

receiver and 9-axis inertial measurement unit. It also uses two high torque airplane motors which

provide more thrust than low torque motors, two propellers, and a carbon fiber chassis for a

strong, light, and flexible frame.
