Buddy 1 is a basic test of rov operation, mainly a user experiance
project. Camera recently changed to refit for retrieving pop cans.
Buddy II is an implementation of buddy I able to carry batteries
and its own onboard computer. The idea is to have a webcam streaming
video over an 802.11 connection.
- K7-500 on a K7M motherboard
- 2 x 108VDC motors
- 2 x sunbeam gearboxes (1 modified, 1 awaiting modification completion)
- 2 x 6" lawnmower wheels
- 1 webcam (will be replaced with videocamera/capture card when proven out)
- colour video camera
- 1 10/100 pci ethernet card (will be used until operation proven out)
- 2 250W inverters awating modification to become HV motor drivers
- transistors for inverter mods
* modified gear boxes (1 done, 1 at 80% complete)
* inverter modifications
* design for computer/PWM interface
* software for I2C controlled pwm for Atmel Tiny13
* linux software bits
Buddy III is a walking version of buddy II. currently consists of a computer model and 1 leg. Grid on floor is 10cm
- frame wire
- 18 gearmotors
- 5 feedback potentiometers
- 18 servo boards (obsoleted)
- K7M motherboard
- 23 Li-ion batteries
- 13 1.4" shaft 1K to 20K linear taper potentiometers
- 14 cell phone Li-ion batteries
- sample ATtiny13's for servo control
- major kinematics software
- completion of I2C PID PWM servo software
[All servo's to default positions]
This is a collection of junk that was assembled because there was nothing else better to do.
built for lack of nothing better to
do, 'the dog' uses a 386 running a qbasic control program under dos. it
bumps around into things. This is not the origional or proper battery
This was put togethor as a test platform for the lawnmowing robot
that nearly destroyed the workshop due to a software bug. This was
meant to use the same configuration as for lawnmower, so that the
software could simply be copied over when it was refined. It was never
used. It did not even obtain its sensors. p.s. dont use 1.5V rotissory
motors to drive such a large robot, gears strip easily. Uses "stacking"
Concept: Effectivly buddy II with the ability to navigate bush. Tracked? Possibly a 'skidder' design...
mini test platform for line following and such.
This little piggy went to ebay.
Built for a competition held by the Vancouver Robotics
Club, line following, did well but didn't win anything. Uses 12V of
Li-ion batteries. Discrete logic control. Currently being revised with
- IR ranger and PIC 16F627 control
- homeing to charging station
This is a tilt and pan project, mediocre success. Picture taken in a mirror.
This is the camera responsable for all the bad photos you see here on this site.
Started because I had the parts, and it was decided an arm would
be usefull around the shop. Then it was decided to build a 18 axis
hexapod, nolonger have enough gearmotors. Project under conditional
halt. Capable of turning and moving up and down
What is better than an office robot to bring you coffee when you need
it, take away your dirty cups, and come when you online order it to!
Major halt on this, turns out that using modified bicycle chain as tracks didn't work too well. This is all plexiglass.
System uses 1 motor with two clutches and two brakes.
These images are 640x480, so if you view them standalone, you get a bit of a zoom in
The pipebot if design for carrying a camera down 8" (20cm) pipe. Its under halt for lack of external interest.
Goodies for this robot include "signal-over-power" with high voltage AC power, for long distance, 2 wire teathering.
Basic idea is that there would be a 1Khz or so high voltage AC across
the power lines, with "DTMF" control codes modulated onto it.
This is a set of two stepper motors with gear boxes. wheels can ride up the side of the pipe without traction problems.
Thats most of the robots as of Dec 29 2004.
