Robotic vehicle
A robotic vehicle has legs and propellers to enable it to walk, fly, and or swim.
1. A robotic vehicle comprising:
a body;
a plurality of legs, each leg being moveably coupled to the body and having a propeller rotatably coupled thereto; and
a controller operable:
in a first mode, to cause the plurality of legs to move relative to the body so as to provide motive force for walking the robotic vehicle; and
in a second mode, to cause the propellers to rotate relative to the legs that they are coupled to so as to provide thrust for flying the robotic vehicle and/or propelling the robotic vehicle in a liquid.
2. The robotic vehicle of claim 1 , further comprising at least one additional leg moveably coupled to the body, wherein the controller is operable, in the first mode, to cause the at least one additional leg to move relative to the body so as to provide motive force for walking the robotic vehicle.
3. The robotic vehicle of claim 1 , wherein each leg comprises:
a knee joint;
an upper leg portion moveably coupled to the body and the knee joint; and
a lower leg portion moveably coupled to the knee joint so as to be moveable relative to the upper leg portion, and wherein the controller is operable to cause the lower leg portion to move relative to the upper leg portion.
4. The robotic vehicle of claim 1 , wherein at least one of the legs comprises a wing portion, and further wherein the controller is operable in the second mode, to cause that wing portion to move relative to the body so as to influence a fluid flow around the robotic vehicle.
5. The robotic vehicle of claim 3 , wherein at least one of the upper leg portions comprises a first wing portion, and further wherein the controller is operable in the second mode, to cause that first wing portion to move relative to the body so as to influence a fluid flow around the robotic vehicle.
6. The robotic vehicle of claim 3 , wherein at least one of the lower leg portions comprises a second wing portion, and further wherein the controller is operable in the second mode, to cause that second wing portion to move relative to the body so as to influence a fluid flow around the robotic vehicle.
7. The robotic vehicle of claim 4 , wherein one or more of the wing portions are arranged to act as aerofoils.
8. The robotic vehicle of claim 1 , wherein each leg is moveably coupled to the body by way of a four degree of freedom joint.
9. The robotic vehicle of claim 1 , wherein at least one of the legs has, at a distal end thereof, a manipulator element for manipulating objects.
10. The robotic vehicle of claim 1 , further comprising a filament dispenser for feeding out and/or retracting a filament.
11. The robotic vehicle of claim 10 , wherein the filament dispenser is operable to sever the filament.
12. The robotic vehicle of claim 1 , further comprising a substance dispenser for dispensing a curable substance.
13. The robotic vehicle of claim 1 , further comprising a pair of substance dispensers for respectively dispensing first and second substances that, upon combination, become curable.
14. The robotic vehicle of claim 13 , further comprising a pair of arms moveably coupled to the body, wherein each of the pair of substance dispensers is fixedly coupled to a respective one of the arms.
15. The robotic vehicle of claim 12 , wherein the substance dispenser or substance dispensers comprise spray nozzles.
16. The robotic vehicle of claim 1 , further comprising an arm moveably coupled to the body and having, at a distal end thereof, a manipulator element for manipulating objects.
